Using SELCO Library Swap, Online Libraries can swap any unwanted items with others libraries who may have use for them. You can also sell/buy items on a library point system basis (no cash). As a guideline when pricing items, each library point should be considered as roughly equal to $1. Public libraries can use the swap service at http://swap.selco.info/index.php. School & other SELS/SELCO libraries will have access to this site in September 2011.
