Do I need a Library Card Number to access the CW MARS Digital Catalog?
To access the CW MARS OverDrive Digital Catalog, a library card should be obtained from your local library.
Your local library can also help locate your number if you may have forgotten it of if you are unsure if you have a card. If you have forgotten your password, you can reset it using this link.
Note: If you do not currently have a library card but access OverDrive with your mobile number, see Can I continue to sign into OverDrive with my mobile number? below for more information.
How do I sign into OverDrive? / How do I access OverDrive?

- Then click I'll Search For A Library.

- On the next page, enter your CW MARS library card number, (without spaces or dashes) and click Next. Enter your CW MARS My Account password. Click Sign In, then Next. You can now search the CW MARS Digital Catalog.
Can I continue to sign into OverDrive with my mobile number?
Yes, for now.
We strongly discourage using your mobile number if you have a library card number.
Between March 2020 and June 2020, OverDrive instituted the ability to log into OverDrive with your mobile number. The first time you signed into OverDrive with your mobile number, OverDrive would register you for an Instant Digital Card (IDC). IDC signup was discontinued at the end of June 2020.
If you signed up for for an IDC during that period and continue to sign in with your mobile number, we encourage you, instead, to use your existing library card number. If you do not have a library card, you can contact your local library. Your local library can also help locate your number if you may have forgotten it of if you are unsure if you have a card. If you have forgotten your password, you can reset it using this link.
IDCs expire one year from your sign up date. Activity on IDCs will NOT transfer to your library card, so it is beneficial to sign up for a library card as soon as possible.
A Library Card also allows you...
- access to physical material from across CW MARS and the state.
- access to other networks' OverDrive catalogs through LEA (see What is "LEA"? below for more details).
- access to Statewide Databases.
- access to databases and additional e-resources provided by your library.
- uninterrupted access to your OverDrive lending history. If you have a library card, you will not be able to access loans, holds, etc linked to your library card when signed in with an IDC.
What are the lending policies for OverDrive titles?
ebooks, audiobooks and magazines can be borrowed for 7, 14 or 21 days. The default is 14 days.
streaming video can be borrowed for 3, 5 or 7 days. The default is 5 days.
Patrons can change the default by logging into their account settings at cwmars.overdrive.com
Patrons can borrow up to 10 titles at a time and place up to 10 holds. Magazines are always available.
Some titles may have set lending times that are different than the defaults.
Where are my notifications in OverDrive/Libby?
Click the bell icon in the top right. OverDrive will notify you when a hold is ready to borrow.
See My hold is ready to borrow. What now? below for more information.
To manage notifications, click the Libby icon in the top right, and then Manage Notifications. Here you can decide if you want to be notified...
- When a hold becomes available
- When a loan is about to expire
- When a loan has expired
- And more!
Notifications are device-specific, so you can set your notification preferences for each device you use Libby on.
After swiping a push notification, you will be taken to your Reading Journey for that title, which displays any previous interactions and activity you had with that book (notes, highlights, time read, etc.).
My hold is ready to borrow. What now?
If you received a notification, open the notification in OverDrive or Libby, (see Where are my notifications in OverDrive/Libby? above for more information). Or go to your Holds list.
You will have a three day grace period to perform one of the following actions:
- Borrow the title.
- Suspend the hold by selecting Deliver later. This option passes the title to the next person in line while maintaining your place on the waitlist. Once your desired suspension period is over, your hold will reactivate, and you'll be able to borrow the next available copy.
- Cancel the hold by clicking Remove hold.
If no action is taken within the three day grace period, the hold will automatically be suspended as a one-time courtesy for 7 days. If no action is taken a second time, the hold will be cancelled automatically.
I received an email that a hold was ready to borrow, but I cannot find the hold. What happened?
You may be trying to pick the item up from the wrong network or with the wrong card. Alternatively, the hold may have been automatically cancelled.
Ensure you are using the correct library card
- Is your Libby app connected to multiple library cards? Did you sign up for an Instant Digital Card but already have a library card? Do you have a Boston eCard? You'll need to make sure you are signed into OverDrive with the SAME account you used to place the hold. If you have multiple accounts, try signing in with the other accounts to see if the hold appears.
Make sure you are in the correct Digital Catalog
- Check the email for details that may help. Who is the sender of the email? If the email came from a cwmars.org domain, then you need to make sure you are in the CW MARS digital catalog. If you are using a LEA Partner Library, the sender email will be from another domain. Make sure you are in the correct catalog to pick up the hold. For more information on partner libraries, see What is "LEA"? below.
Check to see if you waited too long to borrow the hold
- Remember that you will only have 3 days to borrow a hold once it becomes available. After that, it will be suspended as a one-time courtesy for 7 days. If no action is taken a second time, the hold will be cancelled automatically. If the email is older than 10 days, there is a chance the hold was cancelled by the system.
How do I update my email address associated with OverDrive?
You can update your email address associated with OverDrive through one of the two methods below:
Method 1: Through an open hold
- Note: This method requires an open, unavailable hold. If you do not have any holds at the moment, place a title on hold. It can be cancelled after the email address is updated.
- Sign into the CW MARS Digital Catalog in a web browser, (this cannot be done through the Libby app).
- Click on My Account in the top right, and then select Holds.
- On any open hold, click on Edit Email. This will appear underneath the cover art.
- Enter and confirm your new email address. Click Submit. This will update the email address associated with the chosen hold as well as future holds.
- If you have additional open holds, you will have to edit the email address on those, as well, if you'd like to be notified for them.
Method 2: Through the LibbyApp website.
- From a web browser, go to libbyapp.com, (this cannot be done through the Libby app).
- If not currently signed in, follow the steps to sign in. The process will be similar to signing into the Libby app on a mobile device.
- Click the Libby icon in the top right.
- If you have notifications, they'll appear on the top. Click through them until you see a notification card that reads Manage Notifications. Click on this link.
- On the Manage Notifications screen, scroll to the bottom until you see a link that reads "Fix this?" or "Change this?". Click this link.
- Enter your new email address and click Next. The email address associated with Libby will be updated.
- Optionally, update your notification preferences as desired. Note that Libby offers more email notification options than OverDrive. The chosen email address will be used for all preferences marked "Email Notice".
Note that an email address updated using Method 2 will not connected to the email address in Method 1. Because of this, it is possible to have one email address attached to holds in OverDrive and another attached to notifications in Libby. Please keep this in mind if you are still receiving notifications at your old email address.
I was asked to verify my card when picking up a hold in Libby, and now I'm stuck in a sign-in loop; what do I do?
If you receive a message stating that you need to verify your card and are unable to borrow the loan after verifying, you should be able to fix this using one of two methods:
- Patrons experiencing this loop sometimes report a second CW MARS card attached to the account with the same number. Un-linking the additional card may help.
- Click the Libby icon in the top right.
- Go to See Library Cards under CW MARS.
- Click on Actions on one of the cards, and select to Remove Card. Restart your app and try to borrow the item.
- If this doesn't help, you can remove both cards, restart the app, and add the correct card back. Note that if you remove both cards, you may lose your place in your audio and books.
- Alternatively, you can uninstall and reinstall the app. Downloaded items will be removed from the device when the app is uninstalled, but they will stay attached to your card. Once the app is reinstalled, you can re-link your card to the app, and you loans and holds will return. Note that you may lose your place in your audio and books.
I am getting errors in the OverDrive/Libby app. How do I fix them?
For example, you received an error stating "Session Expired", and signing in again does not resolve the error.
The easiest fix is to uninstall and reinstall the app. Downloaded items will be removed from the device when the app is uninstalled, but they will stay attached to your card. Once the app is reinstalled, you can re-link your card to the app, and you loans and holds will return. Note that you may lose your place in your audio and books.
Why does CW MARS only own one copy of an ebook when there are so many holds on it?
Several publishers have recently announced changes to their lending terms that restrict libraries’ ability to purchase materials. We are not always able to purchase a title (or extra copies of a title), even when we know there is high demand for it. In the meantime, we probably have the title you want in a different format, or we are happy to help you find other, similar authors or titles while you wait. Contact your local CW MARS member library for assistance.
What publishers have placed restrictions on content, and what are the restrictions?
Blackstone Publishing placed a restriction on libraries in July 2019, requiring that libraries must wait to purchase select Blackstone eAudiobooks for 90 days after the books have been released to the public.
Macmillan Publishing also announced that as of November 1, 2019, libraries will be permitted to purchase only one eBook copy of newly released titles for the first 8 weeks the book is available to the public. After 8 weeks, libraries may purchase additional copies. During the 8 week embargo, patrons may see long holds queues and wait times for these titles.
What are libraries doing about publisher restrictions on econtent?
CW MARS libraries have joined many other libraries across the country in objecting to these changes. In a recent letter to John Sargent, CEO of Macmillan Publishers, CW MARS libraries expressed their dissatisfaction with the new terms.
What can readers do about publisher restrictions on econtent?
Library users are encouraged to contact the publishers directly to voice their opinion about these changes and their impact on reading.
Why doesn’t my library own more eBooks?
The price that libraries pay to publishers for eBooks is higher than the price charged to consumers. In many cases the publishers charge the library more than the cost of a print copy. We purchase titles on a weekly basis as budget allows.
How do you decide what content to purchase?
Content in our digital collection is demand driven. We purchase requests for new titles submitted by our patrons. We also purchase additional copies of high demand titles to keep holds queues down when budget and publisher rules allow.
Why doesn't my search return any results?
Check the spelling to see if that is causing your search to not find results. The search results will return titles that are in the catalog and/or that are available in OverDrive, but not owned by your library. Some titles are unable to be purchased due to publisher restrictions or titles only being available to individuals and not library networks. Sometimes we will be unable to purchase additional copies of titles due to publisher restrictions (this happens around movie releases or promotions).
Can I donate ebooks I have purchased to the library?
Under current copyright and digital rights restrictions, you are unable to donate eBooks to the library for other patrons to use.
How do I request a title to be purchased?
Titles available to buy in OverDrive but not yet purchased by CW MARS can be requested for purchase.
Titles not in our digital catalog will display a Recommend button. Click this button to request the title for purchase.
If enough patrons request the title, it will be added to the digital catalog, and you will automatically be added to the waiting list once it becomes available.
What is "LEA"?
LEA stands for Library ebooks and audiobooks.
Massachusetts Library Networks are collaborating to bring you LEA, a new and innovative way to gain access to more eBooks and audiobooks. Powered by Overdrive, LEA makes it possible for you to search for eContent in all Networks regardless of your home library.
With LEA, you can access eBooks, audiobooks, and more from libraries across the Commonwealth using your phone, tablet, or eReader. There are 345 partnering libraries with an estimated collection of over 350,000 eBooks and audiobooks!
If you don't see the title you're looking for in the CW MARS Digital Catalog, use your library card to sign in to another Library Network and find it there. Information on borrowing material from participating libraries is discussed below.
