Library Database needed

Hello there,

I'm looking for a application to use as a small book database for a library. I've looked around and tried things like "book collector" and the likes, though it looks nice its not quite what I need.

I would like a database that on one end you can edit/add books and things that you would expect to need for a libraries database. However, i could like a way to lock down the system so that it can't be edited. That way people could view the database without being able to change anything.

A way to check out books and return them would be nice too

THANKS!
