Lisa That may be the theory; but not the way things necessarily work. At times, it appears that approvals are at random. I've validated books on a Monday and seen them on the system by Wednesday. Yet, as has been mentioned before, other books sit for weeks or months in limbo. There is a definite priority for in-house scanned materials as these may be a part of a special request or project. So, with more work being done in-house, it is only natural that outside volunteer submissions are taking longer. While no one from BookShare seems to want to tackle this question publicly, hopefully they are working behind the scenes to figure out how to resolve the log jam.
