Military Library Card
Active duty U.S. military personnel can take HCPL with them wherever they are stationed

If you are active duty military personnel, you can access downloadable media and our databases. If you do not already have a library card but are still in the Harris County area, you can get a library card by visiting one of our branches. For active duty military personnel, a military ID may be used for the purpose of obtaining a library card even though military IDs do not show a mailing address. APO addresses supplied by the applicant are acceptable on library accounts for military personnel. Library cards are free for everyone. If you are not currently in the Harris County area, you can get a library card online using our Military Library Card Application.

TexShare Library Card
TexShare Card allows you to checkout materials from participating public and academic libraries across the state

Harris County Public Library participates in the TexShare Library Card Program sponsored by the Texas State Library and Archives Commission. The TexShare Card Program provides free reciprocal borrowing privileges to registered borrowers of member libraries, academic and public.

The TexShare card allows HCPL cardholders to borrow materials from other participating libraries in the State of Texas. Only currently registered HCPL customers in good standing (no overdue or lost books, and no library fines) may get a TexShare card from Harris County.

TexShare Cardholders visiting from another library system will be asked to provide proof of mailing address, issued HCPL library cards, and allowed full HCPL borrowing privileges with the exception of Interlibrary Loan.

Only HCPL customers registered for 90 days in good standing (no overdue or lost books, and no library fines) may get a TexShare card from Harris County.
