This app great for librarians for two reasons.  One, it saves a lot of time in searching the inside of a book for the publisher, year of print, etc.  Two, it can save a lot of time for librarians who are writing scholarly articles.  Now if only they had an app that retrieved a book's metadata......hmmmm.  Anyway, here is the link in the appstore for easybib:
