There are a few more libraries in OZ now using Librarything for Libraries. I love Librarything and use it to search for new authors, reviews and recommendations.
LibraryThing for Libraries enriches the online catalog with Library 2.0. tools
Just as a point of interest, LibraryThing has over 32 million books catalogued and is larger than the Library of Congress!!
They have also made images of book covers of a million books available for anyone to use for free!
