CASE STUDY: American Archive Digitization

pdf-downloadIn 2011, the Corporation for Public Broadcasting selected Crawford LIFT to provide digitization service for the American Archive Project. A substantial undertaking, the task as outlined was to digitize 35,000 hours of audio and video content across 55,000 tapes, and transcode another 5,000 hours of born digital content from approximately 100 stations from across the nation.


There were a lot of challenges to overcome during the span of this project, but the team at Crawford Media regards challenges as opportunities to learn. One of the project’s initial hurdles was the need to hold the majority of the content in-house, simultaneously. Space in our temperature-controlled, secure vault was reallocated to handle the additional capacity. All told, fifty-eight pallets and hundreds of additional boxes of tapes were stored to ensure safe, efficient availability to our migration team.


Once a strategy to house the assets was outlined, the Crawford LIFT project team had to determine how best to label the thousands of objects from various different locations. In order to alleviate organizational headaches in the scanning process, station-specific barcodes were printed and shipped to each location.


The project team then transitioned to the task of getting the assets to the Crawford facilities. Because materials from stations in Unalaska, Alaska and Guam – locations where truck freight transport was impossible – were part of the project scope, Crawford elected to transport the assets as luggage on passenger flights bound for Atlanta. For those stations in the contiguous U.S., climate-controlled pharmaceutical trucks were used in a series of three runs to transport the tapes to the Crawford vault. The logistical strategies worked to save approximately $85,000 over the term of the project.


After the magic of shipment was done, it was time for the migration team to get to work. To handle the various analog formats, Crawford set up a series of tape bays. Allocated for the project work were three bays for video tapes, two for audio tapes and a transcodel bay for born digital.  The BagIt container bundled up to 27 objects for each source asset, including the media essence files, closed caption files, SAMMA migration logs, technical metadata files, and checksums among others. Nearly 1.5 million pieces of information were generated and tracked during the migration.


Along the way, the team uncovered priceless gems like Robert Frost reading a selection of his poems from WFCR, a Frank Zappa interview from KGNU, an Ayn Rand speech from WFCR, and three long-lost tapes from KQED that were actually interviews with film director Akira Kurosawa, Francis Ford Coppola and George Lucas.


The massive digitization project has enabled the American Archive of Public Broadcasting to grow into one of the most educational and culturally diverse archives in the country. Crawford is proud to have provided the workforce and technology to realize this ambitious project for the Corporation for Public Broadcasting.
