Workshop description: 

If someone were to ask an archivist about lignin, chances are pretty good the answer would cover everything from what role it serves in trees to why it's a concern for the preservation of our cultural heritage. In our increasingly digital world, archivists are less secure in their command of digital objects, what they're made of, their inherent vices, and what factors to focus on to keep their archives viable indefinitely into the future. This workshop is an introduction to the basics of wrappers (packages of digital data), and codecs (digital encoding of information). Covered topics include common wrapper (.doc, wav., mp3, mxf), probing and testing tools for archives (JHOVE, DROID), and codecs (ASCII, UTF, TIFF, JPEG, MP3); with a goal of giving archivists a basic foundation for managing digital collections in archives.


About the Instructor: 

George Blood graduated from the University of Chicago (1983) with a Bachelor of Arts in Music Theory. Active recording live concerts (from student recitals to opera and major symphony orchestras), since 1982 he has documented over 4,000 live events, recorded and edited some 600 nationally syndicated radio programs,  recorded or produced over 250 CDs, 5 of which have been nominated for Grammy Awards. Each month George Blood Audio/Video/Film digitizes thousands of hours of audio and moving image collections. Mr. Blood is an active teacher and presenter at conferences, sharing these findings with members of the trade and collections managers, on subjects such as workflow, best practices, metadata, authentication, and interchangeability of digital information. He currently serves on the technical committees of the Association for Recorded Sound Collections and the International Association of Sound and Audiovisual Archives, the Grammy Foundation preservation specifications review committee, and the MXF AS-07 standards committee (preservation specific wrapper for moving image essences).
