OER Tools

The materials in this LibGuide were drawn from the following searchable hubs for law OERs:


Other sources for finding OERs and affordable course materials:

  • MOM (Mason OER Metafinder) - federated search of 22 OER sources, including several that focus on older materials. Currently also searches the National Emergency Library, which will only be available tmeporarily and is not recommended for long-term use/adoption (you may want to exclude this from your search)
  • MERLOT material search - discover many of the same law materials, presented with user ratings/comments
  • OER Commons - includes video courses, law materials focused on paralegal education
  • Directory of Open Access Books (DOAB) - Directory of Open Access Books is a joint service of OAPEN, OpenEdition, CNRS and Aix-Marseille Université.
  • Center for the Study of Public Domain (CSPD) Publications - The Center for the Study of the Public Domain at Duke Law School promotes research and scholarship on the contributions of the public domain to speech, culture, science and innovation.

Tools from Platforms with Law Content


Getting Meta

In exploring the casebooks and other OERs listed in this guide, consider the following tips about using and assigning such resources:

Checking/fixing links - Many of the open casebooks listed here contain all readings, or a combination of fulltext and stable links to readings, but some rely on links (1) to materials in subscription resources (e.g., Westlaw, NY Times), often due to copyright considerations; (2) to institution-specific courseware, often due to fair use or other copyright considerations; and/or (3) that are subject to linkrot or already unavailable (dead links). While the resource as a whole may still be useful, dead and non-open links will need to be replaced to create a version useful for Law students.


Feature testing - The resources in this guide have not necessarily been tested or evaluated for user-friendly and robust content delivery features. On the assumption that students may choose any of the available formats, a user test of all electronic formats offered should be conducted so that any issues can be identified and addressed.


Accessibility - Standards such as W3C's Web Content Accessibility Guidelines are not uniformly applied in OERs. Some good practices to consider include: headings to structure text; meaningful hyperlinks (not “click here”); descriptive alt-text for all uploaded images; transcripts of uploaded media; readable font sizes and high-contrast colors.


Availability of print/offline usage - For in-depth, sustained learning and reading, users still prefer print; offline access (whether via print or a downloaded digital version) is also often helpful for busy students. The quality of print formats offered varies - from on-demand, soft- or hardcover bound prints from Amazon or Lulu, to self-printed PDFs with stable page references and tables of contents, to PDFs or Word documents with dynamically-linked tables of contents that lack page numbering - and should be considered in assessing ease of use.


Giving assignments - Students may use differently paginated formats (print with stable pagination, device with resizable type, editable format with comments/notes that affect pagination, online formats without page numbering), so references to content should be user-tested for clarity and ease of navigation.

The content creation and hosting platforms for OER casebooks (listed at left under Create your Own OER) are a forum for distributing and sharing your content. In addition, discovery platforms allow you to submit a work for listing as a way to promote your OER:

MERLOT - (signup required) "You have to be a member of MERLOT to contribute materials, but membership is free. MERLOT welcomes all to submit learning materials to the collection."

OER Commons - (signup required) "Submit OER from the web for review by our librarians."

Open Textbook Library - criteria for listing in OTL's catalog: (1) openly licensed; (2) complete textbook available as a complete portable file; (3) in use at multiple institutions, or affiliated with a higher education institution; (4) original.
