The book publishing industry is worried that the chaos of the music industry is upon them. Scribd is a web site that--like all tools--can be used for good and evil. It is quite handy for distributing documents widely that you want distributed. The article mentions that the Obama campaign used it for campaign purposes. However, some are using it to upload current copyrighted literary works:

A search of Scribd by The Times yesterday found copies of Harry Potter and the Half-Blood Prince and Ken Follett’s most recent novel World without End among many bestselling titles, raising fears that the piracy affecting the music industry may have spread to books.

Those are probably gone by now. One problem is that the site owners leave it to the publishers to scour the web site to identify their abused works. If informed, the Scribd staff will remove the material. That is quite a burden, it seems, considering that ten more such sites could pop up at any time.
