Why Sign In

Your San Mateo County Library eBranch account will allow you to access all the new features we have added to our website. These features include:

  • Save your searches
  • Limit and filter search results more intuitively
  • Save Book lists
  • Save your checkout history. (Must opt in first to Recently Returned)
  • Rate, write reviews, and tag items in the catalog.
  • And much more to come...

Your San Mateo Library eBranch account allows you to choose your own user name and ppin. Your library card number and library card pin will be stored as part of your account information. That means that as long as you are logged in to your San Mateo Library eBranch account you will not have to type in your library card number when you want to:

  • Place holds
  • Renew items
  • Pay fines/fees
  • Access some research databases (Some research databases will still ask for your library card but we are working on getting all of them to log you in automatically.)
