There is no minimum age to get a library card, but a parent/guardian must sign for applicants under the age of 16. A child must be present to receive a card. Your signature on your child’s application indicates that you accept responsibility for supervising your child’s use of the library. The borrower or guardian is responsible for the card’s security, for any material checked out, and for any charges incurred.
Customers should report lost or stolen cards immediately as well as changes to their name or contact information (address, phone, email).
St. Mary’s County Library cards may be used at any public library in Calvert, Charles and St. Mary’s County as well as any public library in Maryland.
Kids’ Card: A special card available for our youngest residents under the age of 18. The Kids’ Card is available to get library cards to and encourage reading by as many children as possible.

These special cards can be issued to all youth ages 0-17 (cards expire on their 18th birthday).
Children will be able to check out up to five books (no Book Xpress items) and access all of the library’s online resources.
This is a fine free card and neither children, nor their parents will be held responsible for lost items.
Card holders can place up to five items on hold.
Kids’ Cards cannot be used to place holds through MARINA.
A Kids’ Card may be issued regardless of whether the child has an existing library card and whether that card is in good standing.
