Taking on board some of the things mentioned by Tracy regarding the Library I have now added the facility for members to offer their own books for loan. (you are not actually donating them to the library, you keep them on your bookshelf until someone wants to borrow them)
As was pointed out on the list there are probably people sitting on useful books who certainly don't want to give them away to the library but would be willing to lend them out if there is some tracking in place.
All existing member accounts have been upgraded, if you have an account the library should have already emailed you to tell you this.
You should see a few new buttons when you log in (some of which only appear when you have added your first book)
Use Add new Item to offer books for loan. When somebody reserves one of your books you will receive an email telling you who wants it. Once you have given the book to them you log in and mark it borrowed with the Item Check Out button. Once the item is returned use the Item Check in button to return it to your collection.
You can specify a loan duration if you want and the Library will then alert both the lender and the borrower when books are overdue.
The Library still welcomes additions to it's own collection.
I want to make it clear at this point, The Librarian (me) and ALUG do not accept any responsibility for books lost. The agreement to safely return the books is between you and the borrower.
