Pressbooks is a popular tool for open textbooks, making easy the process of creating, modifying, and publishing. Its overall commitment to accessible design, coupled with the support for interactive assessment, embedded multimedia, and web annotation contributes to high-quality OER.
For users with PressbooksEDU or adapting and remixing OER is simple. Pressbooks User Guide Users can "clone" or copy any public, openly licensed book on the Pressbooks network to their own network then adapt it to their own needs.
For those using the free version of Pressbooks, adapting and remixing OER is still possible. When you find an open textbook on the Pressbooks network, download the file as Pressbooks XML. Download options can be found on the cover page.
Alternatively, you can right-click the link to the Pressbooks XML file and copy the link.
Next, from the Pressbooks dashboard find the Tools menu and select Import. Under Import type select Pressbooks/Wordpress XML. Either upload the file (if downloaded), or paste the URL (if copied).
The Importer screen will allow you to select which parts you wish to include. H5P makes it easy to create
Since you do not have access to the H5P plugins of Pressbooks EDU, duplicating interactive content is not recommended. As always with OER, remember to add the proper CC-licensing and attribution.
Pressbooks has a H5P plugin that allows authors to create interactive content within their books. This is only available through PressbooksEDU or those hosting Pressbooks locally. The plugin is also available in Wordpress, Moodle, and Drupal. H5P has a wide range of interactive content types including quizzes, audio recordings, fill in the blanks, and interactive video.

Pressbooks currently supports LaTeX for all books, offering both the option of shortcodes that automatically convert your formulas and a plugin that allows you to write LaTeX directly into your books.
