If you have a Harris County Public Library Card, then we want your e-mail address! Snail mail costs money and is slow, so we would rather send information electronically. So, if you're getting your library notifications via snail mail and you have a valid e-mail address, then contact us and let us change that. If you plan on getting a library card, then please make sure you fill in your e-mail address on the form. Lastly, make sure we have your current e-mail address. If you log into your account on our website you can double check and edit your profile. We don't want your notifications to get lost in cyberspace because cyberspace won't pick up your holds or pay your fines.
