Here's an introduction from the website:
"Discover, request and review new books. NetGalley is an inexpensive and green way for publishers to share their digital galleys securely. Professional readers—reviewers, media, bloggers, journalists, librarians, booksellers and educators—can all use NetGalley for FREE to read and request galleys they want to review."
I already have my eye on a couple galleys I want to read. But alas, the age old dilemna...too many books and not enough time to read them all. Wish me luck!
