Information about the ProsLib CD, including how it can be obtained, is publically available at
The Hatstand, an invaluable website and
companion Livejournal for Professionals fans.
The ProsLib Yahoo Group is members only, but instructions on how to sign up should be included at the site.
The Yahoo Group includes, in it's files section, an index of all stories currently on the CD. Stories are posted regularly to the messages and long files section of the group, although they are not archived there indefinitely.
Where the author of a story is anonymous, the story may still be looked up on the index of the ProsLib CD. In some cases, where a writer is known to fandom but does not wish their name to be on the internet, the authors name will also be revealed.
