The Liberty Library uses an online web-based automation catalog called MILS (Maine InfoNet Library System).

Your library account number is 14-digits. To get that barcode number, use 2494900000XXXX but replace the Xs with your  4-digit account number to the sequence. Contact the library if you need help with your 14-digit number or to reset your PIN/Password.

Our catalog.

Requesting on MaineCat has been temporarily suspended. Can’t find it in MILS, try MaineCat, a Statewide Catalog that combines and links library collections across Maine, and members can request items be sent to Liberty Library.  A single search scans more than 3 million unique titles and nearly 8 million items.
