Here's the link to "Regional Depository Libraries in the 21st Century: A Preliminary Assessment". I'm pleased that GPO also included related documentation in addition to the document itself.

I agree with John that a "depository library program is a terrible thing to waste" (images of frying eggs run through my mind :-) ). It will take some time to absorb all the documentation, but I'd like to submit one other piece of evidence to the pool: "Government Information in the Digital Age: The Once and Future Federal Depository Library Program".

We've argued long and hard for a 21st century FDLP based on distributed digital deposit and collaborative digital collections (think Napster or Peer-to-peer (P2P) for govt documents!); we've defined our terms and technical requirements (hopefully clearly), shown the exciting possibilities both for libraries and the public (see the FGI library for our related documentation). Only by expanding our ideas about what the FDLP *could* be will we truly create an FDLP worthy of continuing into the 21st century and beyond.
