Commonwealth Catalog

commonwealth catalog - search for books, dvds, audiobooks, and more throughout the state

The Commonwealth Catalog (ComCat) provides all the same convenience and features as the old Statewide Virtual Catalog but with a much more modern and easy-to-use interface, including book jacket images and improved search options. Users can easily select their preferred format for an item when multiple choices are available. Hardcover, paperback, large print, audiobooks, and DVDs will appear together in search results.

For promotional materials and graphics for online and print use, visit the ComCat toolkit page.

If your library is in one of these networks, your patrons can now use ComCat to request library materials beyond what's in your catalog.
