LibraryThing is among booklover sites with loyal audiences that has had success in helping publishers channel galleys to interested readers who are likely to post online/review the books. In October, for example, they’ve had available for request 1,670 copies of 55 titles. Now Sourcebooks is experimenting with an electronic offering: they are allowing up to 2,500 downloads of their recently published IN THE LAND OF INVISIBLE WOMEN to Library Thing members through the end of October.
