Tarulli, a collection access librarian at a public library in Canada, shows public library professionals in all roles how to expand the library catalogue into an online social space and community platform, extending it beyond its role as an inventory and part of the library's physical space into a next generation catalogue. She examines what the elements and features of these catalogues are, with an example from the U. of North Carolina; common concerns regarding them; how they can be used to enhance core library services, such as readers' services, collection development, youth services, and reference; and how frontline staff and cataloguers can collaborate to make the catalogue a tool that benefits the entire library community and provides local information, discovery, and sources. She also addresses factors involved in deciding whether to acquire a social catalogue and how to experiment without investing fully, marketing, and the role of mobile devices in the future, and includes the views of professionals.
