- Basic primer on how PBS functions, as it explains some of the structure of my project. The public broadcasting service is made up of over 300 member stations. Some stations, such as WGBH in Boston, produce a large portion of original programming available on PBS. This includes shows such as Frontlline, & everyone’s favorite - Masterpiece. PBS headquarters, where I’m based, functions mainly as the national distributor of this original programming. This means they process incoming programs and push them out to the national network via satellite and various digital platforms. PBS headquarters, for the most part, does not produce orginal programming. Finally, PBS has a 20 year old agreement with the Library of Congress to deposit Broadcast Masters of programs after PBS’ distribution rights have expired. This is part of the Library’s mandate to collect programs transmitted to the public in the US pursuant to American Television and Radio Archives legislation. This agreement was put into place when physical media was the primary way deposit items, and due to myriad constraints for both PBS and the Library, approximately 1 deposit has been made in the last twenty years. So, the major takeaway of this early morning broadcast lesson is #1 PBS does not hold copyright to the vast majority of material that exists within its tape storage and #2 that member stations have been sending their Broadcast Master programs to headquarters for distribution and deposit with the Library of Congress on every format you can think of for years. There are also some non-broadcast materials as well, such as season previews, public television closed circuit teleconferences & training videos. Consequently, there are now over 100,000 physical tapes in PBS’ remote tape storage, with more being added every day. This is because though much progress has been made to transition to all-digital workflows, the reality is that most programs still send tapes to PBS, not digital files.
- All of these factors led to my digitization initiative project through NDSR My project has three expected outcomes The first objective is the develop selection criteria for at-risk media in PBS tape storage, and I’ve been mainly focusing on this objective for the past few months. In PBS’ case at-risk media means 1” and 2” tape, as these formats face obselence in both playback equipment and skilled operaters. These tapes are also some of the oldest physical media in PBS tape storage and therefore are most likely to deteriorate beyond saving through digitization. There are over 30,000 of these tapes in PBS tape storage. The second objective, is to develop a digitization workflow for the selected media. This workflow will include both the organization and transport of physical media to a vendor for digitization as well as the receipt, ingest, and long term preservation plan for the resulting digital files. The last goal of my project is to make policy recommendations for PBS. You’ll notice I’ve been referring to PBS’ as “tape storage” and not “archives’. This is because PBS does not technically have a tape archive, as they have not been able to develop & implement archival policy that can apply to over 300 members stations and their standing agreement with the LC. Therefore, these policy recommendations relate to both a standing deposit agreement with the Library of Congress as well as suggestions for future internal PBS policy. Extra slide for other pres – more on policy PBS has a 20 year old deposit agreement with the Library of Congress that requires PBS to deposit programs one year after their broadcast copyright has expired. Due to the age of the agreement, this deposit does not include a discussion of digital file transfer Furthermore, PBS headquarters have been functioning as a “de facto” archive for member stations for years and also has an agreement of deposit with the LC.
- One of the most important things I’ve learned is that reaching out to people and organizations may help you fill some of the data gaps you have in your collection, help you answer certain questions,

One of the biggest takeaways I’ve learned from my project so far is that no collection exists in a vacuum, especially a collection like the one at PBS. One of the best things I did after taking a look at PBS’ internal data & systems was to then turn outward to academic and institutional archives, member stations, and other organizations that hold public broadcasting materials. Talk to people. Tell them what you’re doing. Gain interest & help, potentially even gain a potential use or access case for your digitized materials in the process.
