Looking for an ebook you used recently but that seems to have vanished? Let us know right away; we can probably get it back. Our major ebook program is undergoing some changes due to soaring costs and increasing publisher restrictions on usage. A large number of titles will disappear from our catalog this week. The process is designed to leave available anything that’s been used recently, but because of behind-the-scenes technical work, there’s a lag between the vendor’s most recent usage reports and the actual catalog-record deletion. As a result, you may have used a title in the last two weeks and now can’t find it again. Just ask us to recover it, and if our supplier still has it available, we will!
