Borrowing & Getting a Card


Borrowing Periods

The library assigns a borrowing period to each circulating item in the collection, usually one week or three weeks. This period may be extended at the staff’s discretion.


Checked out items will be automatically renewed for six (6) additional circulation periods, unless or until a hold is placed on the item by another patron. Some items are exempt from auto-renewals.

One Card, Infinite Possibilities

Because the public libraries in Allegheny County share resources, cardholders can borrow materials at any of the 70+ libraries in the county and return them to any library in the county. Work downtown but live in Plum, Green Tree, Bethel Park or Franklin Park? Pick up a book over the weekend from your community library, and return it to the library downtown. While you are in the downtown library pick up a CD and return that when you are out in Monroeville for a dinner meeting.

How To Get A Library Card

There are two ways in which to obtain a free library card:

  • Visit the library’s circulation desk during open hours and present personal identification and verification of your current address.
  • Register for a temporary library card online. With this option, individuals 18 and older may reserve materials, but must present personal identification and address verification upon picking up reserved material.


If you are a resident of Allegheny County, you are eligible for a library card, good at Green Tree Public Library, the Carnegie Library of Pittsburgh, its branches and all district libraries in Allegheny County.

To obtain a juvenile library card, applicants must be under 18 years of age. All children’s cards are to be linked to the guardian’s accounts (when possible). 

Green Tree Public Library also offers library cards for residents outside of Allegheny County.

Identification showing name and current address is required.

Expired Cards

All library cards, including non-resident library cards, expire after two years. Library cards in good standing will automatically renew. Patrons who have not used their library card in two or more years will need to contact the library to reactivate their card or, if their record has been purged, apply for a new card.
