Ayer Library


If you are an Ayer Library patron with an active CW MARS library card, you can access a large collection of eBooks, audiobooks, and streaming movies, television series, and Great Courses made available through OverDrive.

Libby is an e-reader app available through OverDrive. If you are just getting started with OverDrive, we recommend using Libby. Libby is the easiest way to borrow and enjoy eBooks and audiobooks from your library and is available for Android, iOS (iPhone/iPad/iPod touch), and Windows 10. Get started with Libby or learn more about it. For a free, online tutorial on using OverDrive and Libby, visit Niche Academy

OverDrive is a collection of eBooks, downloadable audiobooks and videos that you can access using your Ayer / CW MARS library card. If you would like to read a book on your Kindle, Nook, iPhone, iPad, Android phone, or other e-readers, smartphones, or computers, you can use the OverDrive Digital Catalog.

When you enter the Digital Catalog, log-in with your Ayer Library card number (barcode on the back of card) and you will be able to access OverDrive ebooks.

CW MARS OverDrive Reciprocal Lending Agreement

You can now use your CW MARS library card to borrow eBooks, audiobooks, and streaming movies, television series, and Great Courses from other library networks in Massachusetts.

In addition to using OverDrive through CW MARS (http://cwmars.overdrive.com/), you can now also log into:

Boston Public Library – https://bpl.overdrive.com/

CLAMS – https://clamsnet.overdrive.com/

Merrimack Valley Library Consortium – https://mvlc.overdrive.com/

Minuteman Library Network – https://minuteman.overdrive.com/

NOBLE – https://noble.overdrive.com/

Old Colony Library Network – https://ocln.overdrive.com/

SAILS – https://sails.overdrive.com/

On the “Sign In” page, you will see a box that asks you to “Select Your Library from the List Below.” CW MARS patrons should choose “CW MARS Patrons” from the list. Then you can enter your library card barcode to log in.

This process is the same regardless of which library network you are logging into.

There is no “single sign-on.” You will have to sign into each library network separately to access that library network’s eBooks and audiobooks.

You can borrow eBooks and audiobooks from the other library networks. The loan periods are subject to the local rules of that library network and not to the rules of CW MARS.

Massachusetts residents may apply for a Boston Public Library eCard.
