The Bigger Picture: Visual Archives and the Smithsonian
Posts tagged with: Preserving Your Treasures
On Monday, October 27th, four of our finest were available on the Smithsonian's Facebook page to answer questions about preserving your own archival collections. The four archivists at the Q&A have specialties in the preservation and organization of audio/visual material, photos, and digital records (email, digital video, etc.)
This is our fourth year hosting this event and the questions have evolved into increasingly digital landscapes. We also have an increased number of resources online to point you to which we embed in the answers below. If you don't see the question you have, feel free to reach out to us in our forums. We enjoy getting to hear from you through this fun event each year!
Q: Effie Kapsalis, Smithsonian Institution Archives (SIA) - To get things rolling, would any of the archivists like to chime in with their favorite preservation project?
A: Lynda Schmitz-Fuhrig, SIA - I find it rewarding to make digital materials accessible again. I really enjoy researching possible solutions when it seems digital files can no longer be used. I recently was asked by a colleague if I could retrieve audio off a CD that had been mishandled by the addition of masking tape on the media (any type of adhesive on optical media can damage the contents. Also avoid writing on CDs/DVDs). Previous attempts to copy the file were unsuccessful, but I was able to access the majority of it by using some special software. Just because something seems unreadable is not always the case.
A: Dave Walker, Center for Folklife and Cultural Heritage, Ralph Rinzler Archives - Some of the most exciting preservation projects we have worked on are the home recordings and impromptu performances captured of artists like Lee Hays and Pete Seeger. A recent tape we uncovered featured Weavers’ singer Lee Hays playing guitar and singing with a little boy he was babysitting. This candid snapshot of sound helps to paint a more complete picture of an artist and humanize him in ways the records he performed on might not.
A: Michael Pahn, Archive Center, National Museum of the American Indian - I love seeing people connect with the materials in our collections, and preservation is an important step in making those connections. If a document isn't stabilized enough to handle, we can't digitize it and put it online. If a motion picture film has shrunk and deteriorated, no one will be able to watch it. Preservation is key to providing access. The most rewarding part of my job is hearing from people, often tribal community members and tradition-bearers, who have deep interests in, and knowledge about, the materials in our collections. NMAI recently preserved a series of silent films from 1923, and were able to share the newly-restored footage with the community. It has been extremely rewarding to hear how exciting people are to see the films, and to learn so much more about them from the community.
Q: Do you have any best practices for storing digital file
A: Lynda - We preserve digital records (both digitized and born-digital). The practices we follow include the files being stored on servers that are backed up regularly. We also have our materials on two sets of LTO tapes. For someone dealing with their own personal digital archive, it is wise to have two copies of the files. Try to store one of the copies somewhere else as well. CDs/DVDs and USB thumb drives have their limitations but can work as a temporary measure. It is important to check the files regularly and migrate them to other media to avoid obsolescence. Hard drives can be a good option. Digital preservation is an ongoing task. There also are cloud-based services, but be sure to read the terms of service carefully. You need to know what they plan on doing with your files and their plan in case they go out of business.
Q: We have two fine art photographs that are showing signs of buckling in their frames. This occurred after relocated to humid southeastern climate from New Mexico. Paper does not seem to be straightening out - can anything be done to re-flatten these two images?
A: Effie - Thanks for your question! Here is a post with some great tips on flattening out archival materials. It is a fairly labor-intensive, elaborate process, so if you need help from an conservator, you can locate one here.
Q: What is the best way to capture and save AVCHD video footage? I've been using Adobe Prelude but am not sure the best codec to use for archival storage and later editing in Premiere Pro.
A: Lynda - Digital video is tricky and is there no consensus on what the best codecs for preservation are. Those creating digital video should go for the highest quality possible: uncompressed and lossless is desirable. Files that are too compressed are difficult to preserve. Audio tracks on the video should strive for a minimum of 48 kHz and a minimum of 720 by 486 pixels at 30 frames per second.
Q: What is the best way to store audio tape (temperature, containers. etc.) to maintain integrity of the tape itself? I have nine cassette tapes of my grandfather narrating his life story. I've transferred them to CD and mp3, but I don't know if the original exists, so I'm concerned about keeping the tape's integrity for as long as possible.
A: Michael - Audio cassettes have the benefit of being made of polyester, which is one of the most stable plastics around. The basics for making sure that your audio cassettes last are: keep them in cases, keep them out of direct sunlight, and keep them somewhere in your house where the temperature and humidity do not fluctuate much (so not in your attic or basement). Changes in temperature and humidity have a major impact on the long-term viability of magnetic media. For some additional information, take a look at the Library of Congress' collections care page for sound recordings.
A: Dave - Magnetic audio tape does best in cold dry environments, ideally between 50 and 60 degrees Fahrenheit with a consistent relative humidity between 30% and 40%. You can extend the life of the tapes by keeping them away from strong magnetic sources (motors, electrical fixtures, loudspeakers, vacuum cleaners…etc.) and by storing them vertically, like books. Because the materials and dyes used to create consumer tape boxes are unknown unless tested, it is recommended that the original housing be replaced with enclosed inert plastic polypropylene cans. If stored well, open reel tapes can have an expected shelf life between 35-50 years and between five to 15 for audio cassettes.
Q: I am the head archivist for my college radio station at SUNY Fredonia and we have tons and tons on reels. We are in the process of getting our reel-to-reel machine fixed and I haven't worked with a reel-to-reel before, let alone digitizing old reels. I need to know a few things: what should I be most careful with when digitizing the reels and should I practice using a reel to reel on a separate machine? Also, is there any other advice or direction you can give me? Thank you very much!
A: Michael - First of all, be certain to have the reel-to-reel machine fixed and checked out by a qualified technician. It's the first step in your signal path, and it's going to be in direct contact with your original recordings, so it's very important that it be of a high quality and in tip-top shape. The other important detail is to get your output and input levels set well, which is going to take attention with each tape you digitize. Having the input level set too high, for instance, can result in digital distortion which, besides just sounding bad, is lost data. There are some great, and highly technical, resources online for audio preservation, such as this from Indiana University. Another great resource is the Sustainable Heritage Network, which targets tribal archives, libraries, and museums, but has very useful information for everyone.
A: Dave - Open reel tapes are fairly fragile so you’ll want to make sure to handle them with care prior to playback so as to not scratch or otherwise deform the plastic tape. As Michael suggested, it would be a good idea to have any machines serviced and calibrated by a knowledgeable technician so that you’re able to capture the most amount of information stored on the tape when it’s time to digitize. Before digitizing, you’ll want to put together a digitization plan that outlines what the goals of digitizing the reels are. Definitely check out the Sound Directions: Best Practices for Audio Preservation for a full walkthrough of what goes into audio digitization at Harvard and at IU-Bloomington. Another tip: if you find tapes that shed grey or black particles when handling, it may have the dreaded “sticky shed syndrome” which affects polyester backed tapes and should not be played back until a specialist can treat the tape! Hope that helps and feel free to reach out off-line for more specific guidance at: email@example.com.
Q: Where can I find a good manual to start to work with films archives? I work in a museum in Chile and it's very hard to get some material. Thanks for this opportunities.
A: Michael, A great place to start is the National Film Preservation Foundation's "Film Preservation Guide." Another great online guide is Film Forever, which is sponsored by the Association of Moving Image Archivists. It's focused on home movies, but you should check it out.
Q: Can you recommend me a text or book on how to assemble a catalog of a cinematic file, and if you know some place where I can find good examples of such catalagos.
A: Michael - There are many, many different ways to catalog moving image materials, and there isn't a single correct approach. The Association of Moving Image Archivists (AMIA) put together a publication called the "AMIA Compendium of Moving Image Cataloging Practice." This document pulls together responses to a survey that AMIA sent out about moving image cataloging, and includes guidelines and catalog records from several different institutions, each of which does things differently than the others. The AMIA Compendium is available for purchase from the Society of American Archivists.
A: Dave - A good place to start might by the “The FIAF Cataloguing Rules For Film Archives “ which covers the recommended basics for arranging and describing archival moving image materials. A hosted version can be found here which also includes some examples that you might find useful.
Q: I already have an MLS from a few years ago but with a focus in public service. How can I now shape a career path to become an archivist?
A: Marguerite Roby, Smithsonian Institution Archives - Hi, check out this great blog post regarding archival career advice. It includes links to several other resources as well.
Q: I've got approximately 150 very old vinyl records taken from my great-grandmother's house post-Katrina that were completely submerged in mud for at least three days following the storm. I've been cautious in my attempts to restore them, fearing the dried mud and dirt particles would scratch and damage the modulated grooves inscribed on the vinyl. Any advice from you guys on the proper way to restore and hopefully salvage an awesome record collection is greatly appreciated!
A: Dave – The records may be recoverable, and we’re glad you've been cautious. Given the dates your great-grandmother's collection may cover, our worry is that some of them may not be vinyl but made of other materials that are more vulnerable to solvents including distilled water! It is first important to identify what you have and sort them based on type before attempting any recovery. Do take a look at the following links, including one written for #presweek and more that get into the nitty-gritty, literally. This article “Preservation Week: Caring for Your LP Records” is a great short overview. The Library of Congress has an excellent tips sheet on caring for audio recordings, scroll down for cleaning recommendations. Do note that is meant for general cleaning, when the type of record is known. Dried mud can be very tenacious, so it may take several sessions to clean a record, starting with a soft brush to loosen the bulk of dirt before wetting. (The brush can also help you remove dirt from the covers.) Do also note that solvents may affect the labels and their adhesives, so take care to work a small section at a time. For disaster recovery in general, do take a look at guides on our disaster page.
Q: I've been making field recordings of musicians performing live in Rhode Island for the past few years and have accumulated days of material; my dream has been to establish some sort of online archive for these recordings & everyone I've talked to has been enthusiastic about the idea but I've been struggling with questions of how to actualize it, i.e. as more than just a dumping ground for files. Would love recommendations of existing online collections (I of course am already familiar with the Lomax archives!) that present material in dynamic ways that highlight interrelation, especially incorporating hypertext, as well as any other suggestions for making such an audio archive as interactive as possible.
A: Lynda - A few links you might find interesting from the National Museum of American History and the Center for Folklife and Cultural Heritage.
Q: I'd like to know what digital tools you use to help tease out the text on difficult to read documents - such as faded documents, or documents where the writing from the backside is interfering, etc.
A: Effie - We have a great summary of some steps you can take to enhance legibility of documents.
Q: I work in college archive that is working to preserve student blogs. How would you recommend going about this especially if the blog is still active?
A: Lynda - If the blog is still active you could capture it at regular intervals. There are both open-source and commercial services that provide web crawling. The WARC format is an established archival container format for web crawls. The International Internet Preservation Consortium has some great information as well. And you can read about our web and social media archiving efforts here.
Q: Hi - we need to transfer DAT audio to hard drive - any advice on this?
A: Dave - The best way to transfer a DAT to a hard drive is by going digital-to-digital. On most DAT machines, the AES/EBU output provides a stereo digital output which can be captured 1:1 in a digital audio workstation. You will need an interface attached to the computer with AES/EBU inputs and will need to clean the DAT machine prior to playback to avoid any errors and dropouts.
A: Lynda - You can also read about our DAT project here.
Q: What sort of degree/education should I pursue to specialize in Audio Digitization? From what I've read, this field is still fairly new and there exactly a direct pathway.
A: Dave - Digitizing archival audio is an activity which stems from traditional archival practice but one that requires strong technical backgrounds in audio engineering, material science, and digital preservation. For someone interested in working specifically with analog audio media, a Bachelors of Science in Electrical Engineering or Audio Engineering would provide a solid foundation for understanding the principles of recorded sound and would prepare someone for a career in troubleshooting equipment, dealing with problematic media, and obtaining the highest quality transfers. Since the field is still so new, there is no direct pathway for a career in audio digitization but having ample experience recording onto magnetic tape and operating studio equipment is an absolute must. For those interested in archival work, there are a number of universities which offer Masters of Library Science degrees within which someone could specialize in any number of special formats such as moving image film, obsolete photography, digital records, and audio media.
Q: I have an old color photograph from 1956 that had been partially exposed to light while in a frame so that now half the image is mostly white while the rest is very washed out. What is the process to restore old photographs, can old photos actually be restored to close to their original state, and do photography shops do this or do I need to find a SPECIALIST who does this?
A: Marguerite - Unfortunately there is no chemical process that can restore faded colors from a photograph. Your best option would be to scan the image and digitally restore color in a program such as Photoshop. I don't know that you would need a specialist to accomplish this, but you would have to pick up some technical expertise. If that is not a viable option, you can search for photo restoration services online where you can submit your digital file for color servicing
Q: Hello - I had a question regarding CD storage. How does the SIA deal with a large volume of CDs? Do they stay in the original jewel cases are they moved to something slimmer/another method of storage? My collection is getting a bit too large for the space I have and am looking for ways to condense the storage space without jeopardizing the CDs (many are out-of-print classical CDs).
A: Lynda - Be sure to store your CDs standing up as opposed to flat. Tyvek enclosures can be used to save some space and are archival. If we receive a CD missing a container or has a problematic enclosure (cracked, dirty, etc), a Tyvek envelope is used.
Q: I would like to know your opinion regarding cloud-based storage. Is it reliable? Is it a good alternative to a hard drive?
A: Lynda - Cloud-based storage can be a good alternative depending on your needs. You do need to read the Terms of Service from the provider very carefully. You want to note what they will do with the files (can they post your pictures on their website without permission) and what is their plan in case they shut down. Do you feel comfortable letting someone hold your materials? What type of access do they provide (24/7)? Can you easily retrieve/remove your files?
Q: How would I preserve paper/cards from the 1930's through the 1960's? I also have some war ration stamps from WWII, how would I preserve those?
A: Lynda - It is usually best to keep papers organized in archival paper folders and boxes. According to the British Postal Museum and Archive, if it is coated on the back with adhesive known as gum, humidity can cause stickiness and dryness can cause brittleness. Each sheet of stamps should have its own folder.
Q: Also, is there a different way to preserve newspaper?
A: Effie - We happen to have a forum post on preserving newspapers from our conservator on this! Check it out!
Q: I work in an archive with no collection management policy and we have a massive backlog as well as a constant uncontrolled influx of new materials. How do you manage a massive collection? How to you process backlog while capturing new items when they come in?
A: Lynda - A collection management policy is important and a first step. A solid inventory of the backlog and documenting what new materials are coming in would help. Depending on the types of materials, minimal processing might work until a plan is in place.
A: Dave - When dealing with audiovisual material, we find it helpful to reduce backlogs by documenting the peripheral information written on the media housing as the collection gets processed. Without playing back each disc or tape, it is difficult to know exactly what is on the media so any handwritten information (track list, artist info, location, date, tape speed…etc.) can be useful for researchers as they make their way through the collection. This cursory documentation can help to prioritize items for digitization as well. Hope that helps!
A common inquiry I receive from Smithsonian staff is whether it is better to keep their files in electronic or paper format. The best answer to this question is "it depends." There are several factors to consider.
1) How long do the files need to be kept?
Paper files, especially when accumulated over a long period of time, require a lot of physical storage space, but if the space is cool and dry, little needs to be done to preserve and maintain them in the long-term. Electronic files generally require little space, but must be regularly reviewed to determine if they need to be migrated to new media or converted to a new file format to ensure they can be accessed in the future.
2) Does one format have more value than the other?
A common example of one format having more value is documents containing signatures. Signatures are often proof of an agreement or testimony. Traditionally, they have been handwritten on paper documents. These paper documents with original signatures are generally necessary for ensuring the authenticity of a signature and are therefore more valuable than a scanned version of the document. The technology surrounding digital signatures, however, allows for the electronic file to ensure authenticity and a printed copy is not as valuable.
3) Is one format easier to use?
In the 21st century, most documents are created electronically and some just don't translate well into a printed format. All sorts of reports and even the data tables can be printed from a database, but printouts just can't be used as efficiently and the database itself can. Another example is a website. A printout does not allow a user to click on links or even give any indication of where the link goes. Not to mention the audio and video elements of a website do not translate at all in a printout.
The opposite can also be true. It is not uncommon for many different electronic files to be printed and compiled into a single printed document, such as a publication. A user could identify all of the electronic files and then attempt to read them in the appropriate order, but it would be easier just to look at the paper version.
4) In what format are the majority of the records already?
There can be value in having all related records in the same format (paper or electronic), but scanning or printing on a large-scale is time-consuming and potentially expensive. It is often best to choose the format that will require the least amount of printing or scanning. A cost-benefit analysis should always be done prior to converting files to a new format. Leaving existing files as is and documenting which files are paper and which are electronic may be a reasonable alternative.
In some cases, there may be significant benefit to maintaining files in both formats. One should be designated as the official copy – the format that will be maintained and preserved – and the other as a reference copy. An electronic version of a document may be suitable to maintain locally for quick reference or electronic searching while a paper version designated as the official copy could be stored off-site and retrieved if needed. Electronic files designated as official copies may be printed to create a paper file that can be easily browsed.
The decision to maintain files in paper or electronically is not an easy one, but by thinking it through and asking the right questions, a solution can often be found that will meet everyone's needs.

Welcome to Throwback Thursday! This holiday season, I hope to inspire you to take a trip down memory lane to the land of erstwhile and bygone days of the family photo album. What better time to pull these one of a kind treasures off the shelves than during the family festivities! Recently over the Thanksgiving holiday, I rediscovered my own family’s quasi-prehistoric, long-forgotten photo albums. As I flipped through the pages looking at photos of my mom, tan and beautiful on a beach somewhere before I was born, or at my younger sisters giggling at birthday parties, and awkward middle school outfits and family photos, I thought what a great gift it would be to share this album with my siblings. If only my parents had used a digital camera- then I could just click and share! So simple, right?
And yet, even though with the ability to share my digital photos so easily, they are scattered throughout the internet, on computers, phones, flash drives, and attached in emails. Not to mention the preservation issues with digital images. Perhaps this is why it is refreshing to view these unique hand held albums of carefully chosen and collected photographs that tell a story in a cohesive pattern.
So, this holiday season, if you too have the urge to dust off those family photo albums and share them digitally with your loved ones, then this post is for you! Or better yet, digitize them, and then create a physical copy to give as a holiday gift, just like the original. You could even supplement the facsimile with your new digital photos to add to the legacy! To help you, my colleagues and I have assembled some useful tips on how to digitize your family/travel photo album or family book (or even your grandmother’s handwritten cookbook) and make a physical facsimile:
- Here is our recent answer with links on how to digitize your family photo album or historic book and create a physical facsimile, from our Collections Care Forum.
- The New York Times also answered some questions about how to scan your photographs and photo album in this helpful Q & A session.
- May I also suggest you take the opportunity of viewing the full-length television program Jefferson’s Secret Bible while it is still available for viewing on the Smithsonian Channel. Your object may not be as technically complex, but it is still a fascinating story and instructive opportunity on creating a physical facsimile.

Holiday family traditions are some of the things that people look forward to throughout the year. For my family, that would be the annual Christmas party. This is an unusual tradition in a Jewish family that emigrated from Russia at the turn of the 20th century.
That's my Grandmother, Sally, on the lower left, her 4 brothers and sisters and her mother. It was her younger sister, Frankie, on the upper left, who started the family tradition that lives on today. As an adult, Aunt Frankie lived in New York City and before she got married she shared an apartment with a roommate from Chicago. As the story goes, one year the roommate could not get home for the holiday. Aunt Frankie decided to throw a party for her and invited her own extended family, which at that point lived in New Jersey and New York. The party has been held each year since then.
I'm not sure in exactly what year that first party took place, but in 1939, my mother attended the party. She is the second on the left in the first row.
And at the 1940 party this picture was taken of my Grandma Sally, her 4 brothers and sisters and their spouses in front of the Christmas tree.
Grandma Sally is in the middle of the back row with her husband, David, to her right. Aunt Frankie is wearing the pinafore and her husband, Wally, stands behind her. Nearby is the piano which was part of the entertainment at the party for many years.
In 1982, this picture was taken of Aunt Frankie's extended family. Aunt Frankie is in the middle row on the left with her children, grandchildren and in-laws. Frankie's eldest grandson, sitting on her lap and making a silly face, now has a child of his own as does his brother on the far right. Cousin Francie, one of Aunt Frankie's daughters, on the right with her arm around the boy in red pants, now hosts the party. Even after the passing of Sally and Frankie's generation, we still celebrate on Christmas Day along with the four generations of family that live in an ever-widening circle from Massachusetts to Virginia to California and points in between.
There are many traditions that are part of this family gathering. For example, we always have a Christmas tree and when Hanukkah and Christmas coincided, we light the candles on the menorah. The menu has remained fairly unchanged over the years. The feast includes turkey, stuffing (with and without nuts), beef tongue (don't knock it till you've tried it), baked beans, a chopped cabbage salad (served in the same huge bowl), cranberry sauces of various kinds, and of course a variety of delicious desserts.
There are other elements that make this tradition so rich including shared stories of past parties, family recipes and cooking rituals (the preparation of that chopped salad begins days in advance). Cousin Bill, Aunt Frankie's son, wrote and recorded a story for a public radio station one year that we listened to together during the party. We have also heard music, poetry and comedy records and there were even a few years where some of the cousins performed magic tricks. All these things are part of the history of a family tradition. There have been many photos and videos taken over the years to record the parties and we love to look back at images of past gatherings. Sharing our memories brings great pleasure to us all.
Preserving these traditions takes some effort in collecting and organization. The Archives has written about this before and it seems timely again.
Here are a few ideas about saving stories, recipes and video/audio recordings:
- Create a journal. Tell the story of an event. Share it with other members of the family to capture more details. Including information about who, where and when comes in handy when you want to recall some detail from a previous event.
- Write down and share recipes. Take pictures of food (tablets and smart phones are great for doing this). Write down a recipe and save it on your computer. Include information about who made that dish, its origins and family memories and stories associated with it.
- Make video/audio recordings of people singing, telling stories, reading poetry, or in the case of my family, doing magic tricks. It is easy to download these files from a camera/smartphone/tablet to your computer.
- Scan paper documents/pictures. Today's all-in-one printers make it easy to scan a document. And there are hand-held scanners that allow you to copy images/documents from a book or album.
- Save these files on a computer and organize them. It is good to name and group files by date, location or name so that you can find them later.
- Make backup copies in a different place, for example on a hard drive, flash drive, CD/DVD, or the cloud.
- Save hard copies of select files. Pick the best, or most favorite and print them out. Create a scrapbook that can be shared.
Taking a little time and effort will help to preserve family traditions and create a legacy to share. Remembering the sounds, smells, tastes, laughter and warm feelings bring us together again over the miles and the years. So, pass the turkey and the beef tongue and don’t skimp on the chopped salad!
