Many of our clients at Forum One produce large numbers of PDF documents (reports, studies, policy briefs) which then are placed in a "documents" section on their web sites. The challenge these organizations face is then making these documents as widely accessed as possible.
One way to increase attention to documents is to use Scribd, a third-party document sharing site (or in shorthand, "YouTube for documents"). We have had good luck at Forum One using Scribd for our clients.
