You can place a hold and have the book sent to the branch you visit. Just select the “Place a Hold” button from the left side of the catalog screen. You will need your library card and pin number. Your pin number is often the last four digits of your phone number, but library staff can look it up for you if you have your card.
If the item is available it will take a few days to get to your branch. If all of the copies are checked out it might be a long wait depending on how many other people have asked for the same book. If you can’t wait for the book, and can’t visit another location that has it in stock please ask a librarian to recommend another book to help you.
