There is a nice bar / cafe at 200 Little Collins St in Melbourne called Stellini, and Frank has allowed me to start a book seat there.
The book(s) are free with the requirement that if you take a book, then you leave a book behind. It would be nice if you signed the books so we all have some history of how often they are returned etc etc. If you felt like sending me an email about the book you take or leave this would be good.
So when your in town, drop into Stellini, say hi to Frank and pick up a free book.
The current book is: Programming Collective Intelligence, Building Smart Web 2.0 Applications
UPDATE: It turns out this is a common idea and there is a web site for tracking books here.
