how do i renew a book
First of all, has your account expired and are you using the correct PIN number? If either one of these is the reason you can't get into your account you will need to come to any branch of the HMCPL system with card number or photo ID and anyone at the public service desk can pull up your account, renew your privilege or help you change your PIN.
I don't know if you have ever renewed items online but here is the explanation FYI:
To renew items online, go to the Huntsville-Madison County Public Library website (hmcpl.org) and click on 'My Account-My Catalog.' This will open a screen on which you will see at the top right corner a place to log on. You will click 'Log On' and a screen opens in which you can enter your complete library card number and PIN number. Once you are logged in, click on 'My Account' (also on the top right of the screen). Click on the 'Checkouts' tab. You will see all the items listed that you have checked out. You can click on a box beside each item that you want to renew or you can select all of your items to renew everything, then click the 'Renew' button at the bottom of the screen. Your items will be renewed and the new due dates will appear.
