#nttw4 talk, December 5, 2019, Dave Rice at #nttw4,
#video at https://twitter.com/nttwconf/status/1202509295973216257
Good morning,
During my first full-time archivist gig, I worked with a large audio collection
and, in adherence to the best practices of my community, would digitize audio
tapes to Broadcast Wave Files. I was a new archivist and working as the only
archivist in a media organization so I felt that relief from looking to the
best practices of our communities as a way of reducing my own decision-making
