We now offer hoopla!


The Book Drop is OPEN 24/7


Although we’re really looking forward to welcoming our patrons back into our library, it’s clear that we will need to take a step-by-step approach in order to appropriately prepare our building and implement systems to keep both our staff and patrons safe. 

You can place a hold on any library item using the online catalog (login with your library card number and phone number as your password) on our website or by calling the library. After the book is located, you will receive a phone call and given a 2-hour window for pickup, usually within 24 hours from when the hold was initiated.  Just call the library when you’ve arrive in the parking lot and a staff member will place your items on a table outside of the front door for you to pick up.

Curbside Pickup Hours

Due to the high volume of library card requests, please allow 72 hours (3 days the library is open) for processing.  Thank you for your patience!
