Loading Ebooks on Patrons' Devices

If possible, patrons and staff should use product websites or apps to read ebooks (whether borrowed from the library or purchased). However, many platforms do not meet the needs of print disabled readers. In these cases, print disabled readers or someone on their behalf (such as library staff) may remove digital locks in order to load the books onto another device or using different software.

Please note that this process has been fully tested for purchased ebooks, but not for library or rented ebooks. If you are having any issues, please contact us.

Similarly, if you have any suggestions for improvements or have found a simpler method to remove DRM from ebooks, please let us know.

Legal Note and Digital Locks on Audiobooks

These actions, specifically to help make books accessible for print disabled readers, are allowed under the Copyright Act Section 41.16.

While this means that digital locks may be removed from audiobooks as well, the process is more involved and may need further research depending on the platform. Please note that some platforms, such as OverDrive, do not have digital locks on their audiobooks, so may be transferred to other devices, loaded in other software, and burned onto CD without any further steps.

If you have questions about digital locks on audiobooks, please contact us.
