I’m only linking to the program description of the speaker who told us about the transition of the Anaktuvuk Pass school/community library from Dewey to the wordthink system.
The Wordthink system is based on words rather than Dewey. I think it is a good choice for small collections and Anaktuvuk Pass reports more materials checked out. Teachers are finding it much easier and faster to find appropriate materials for their classes.
The transition was made easier because the collection had to be boxed up for a library renovation.
