MANAGING DIGITAL VIDEOFrom Practice to Theory

"It's a rather rare phenomenon for an established medium to die. They usually expand wildly in their early days and then shrink back to some protective niche as they are challenged by later and more highly evolved competitors . . . but some media do, in fact, perish." …………. Bruce Sterling Dead Media Manifesto

Speaking of the Tape Library (Intellectual)

Speaking of the Tape Library (Physical)

Weeding:

Programs dating back to 1981.

Lightly culled during 2005 facility move. Library is considered a working library and environmental conditions are access storage.

Digital File Generation

Digitizing Program Began in 2007 with the purchase of first file playback system.

Format of programs played.

Data from Leightronix playback logs

Nov Dec Jan Feb Mar Apr

Loss of 1 terabyte of programs

Worst Case Scenario

What we lost

Upside: Didn’t lose much content because we are still a tape based house.Some of the lost content was doomed anyway

Upside: Didn’t lose much content because we are still a tape based house.Some of the lost content was doomed anyway

Depending on set up: Staff Time Another play on old

tapes 3000 hours

What We Gained A fresh start Unique identifiers or a

better naming convention The ability to track

digitized programs though the system

An easier way to count different categories of programs (local, import)

What We Gained (continued) A hard look at our

Collection Development Policy

The impetus to weed an uncontrolled collection

Discussions about access

The American Library Association defines collection development policies (CDP) as “documents which define the scope of a library's existing collections, plan for the continuing development of resources, identify collection strengths, and outline the relationship between selection philosophy and the institution's goals, general selection criteria, and intellectual freedom”.

What We Gained (continued) Discussions about new

content management solutions

The development of a records management schedule for digital files
