Merlin mentioned the CD/cassette set ?Getting Things Done Fast" yesterday. I did a quick WorldCat search (it lets you search library catalogs worldwide). Unfortunately, not many libraries appear to own it. Only 9 libraries have the CD version and only 5 have the cassette version (compared to >1000 that own the Getting Things Done book and >130 that own the Getting Things Done audiobook). Those who live in LA have a good shot though. If the LA Dept of Water & Power library lends to the public, they are the only library listed that owns a copy of both the CD and cassette version. But a glimmer of hope is that the Half Moon Bay library isn't among those listed, so there may be more unlisted libraries out there that own it.

Good luck....
