Hypothesis is an open source web annotation tool. You can use it to enable private or public commentary, personal note taking and highlighting, or facilitate discussions between students. This is a web-only tool, so comments and annotation will only be visible in the webbook.

Users must create an account with Hypothesis. Although students can make public comments on materials, it is recommended to use the Groups function in Hypothesis to limit comments and discussions to your class. 

If Hypothesis is not enabled, please contact Some features must be enabled by an administrator.

Once Hypothesis is enabled for your book, you can customize where you want Hypothesis to appear and how you want readers to be able to use the tools under the "Settings" page in the left hand toolbar. The Hypothesis toolbar will then appear on the right side of the public webbook where you have enabled it.
