Can you help me find a resource?

I usually have problems (In a work environment) of lending a book out, and then the person I lend it to lends it to someone else who then...

In my worst example, I had 2 text books that I brought in for a student use, he leant them to another girl that came into the lab... I asked when my student was leaving to find out where the books were, and then when I was leaving the lab, I asked the girl who had them... who did the... wait, when I moved I brought them back in to give to you...

So then it turned out that once they were brought back in I wasn't around, and another girl borrowed one of the books and the staff scientist borrowed the other...

This is of course borrowing that took place for several months each set of people.

My husband uses Library Thing and loves it. It has a tags feature that he really likes. I think the tag feature could be used to track who has it checked out.
