Liz, who keeps us abreast of law-related goings-on at one of our local public libraries, points out that LibraryThing now has a LAW Library Thing going-on with lots of law library catalogs making their appearances, including some of the biggies around the county.
LibraryThing is an excellent teaching tool (for grade school on up) and an invaluable cataloging option for many small libraries and especially private collections. It also keeps growing, and growing, as Things tend to do, though not necessarily insidiously.
