I think that we would be served by some codification of how we handle this library so ...

I suggest:

Anyone wishing to lend a new book to the library should start a new thread indicating that they have the book checked out.

Anyone wishing to borrow should post interest to that books thread and send a PM containing usps contact info and other pertinent contact information to the current holder of the book.

When a holder of a book forwards the book to the next member a post should be made to the thread for that book stating that the book is in the mail and to whom (no personal info in the thread just the members handle is fine) a PM should be sent to the next member in line indicating that the book is on the way and any pertinent tracking (ups, fedex etc) info if there is any.

Anyone holding a book is responsible for monitoring the forum for interest in the book that they are holding and for the postage of forwarding the book to the next member in line

Postage is expected to be cheapest available unless the parties to the handoff agree otherwise.

Should there be more than one member interested in the same book, requests should be handled in date order as recorded in the posts to the thread.

Is this agreeable? Is this complete? Any other suggestions?
