Library Cards

Free Library Cards

Library cards are free to residents of San Marcos and Hays County. Children from Caldwell and Guadalupe counties, who reside in SMCISD boundaries, are also eligible for a free card. Residential and full-service cardholders may borrow up to 20 items at a time.

Enhanced Library Cards

An Enhanced Library Card is a San Marcos Public Library Card that has a person’s name, picture, and other personal information printed on it. This may possibly be used as a supplement with other documents to prove your identity. You will need to check with organizations/entities with which you would like to use the Enhanced Library Card as part of establishing your identity to determine if/how the Enhanced Library Card can be used for this purpose. 

Enhanced Library Cards are only available to residents of San Marcos or Hays County ages 18 years and older.

Enhanced cards are issued every Wednesday from 2-4 pm on a first-come, first-served basis. If you cannot come during this time, please e-mail with your name, date of birth, and availability and someone will get back to you to schedule an appointment that meets your needs!

Out of county residents may purchase a full-service card for $56.00 per year or $28.00 for three months. For a fee of $11.00, a limited service card is available for 3 months with a loan limit of two items at a time.
