PressbooksEDU and the Pressbooks user community have created robust guides and tutorials for using Pressbooks. The following guides and tutorials are a good place to start.
Cascadia’s Guide to Pressbooks
There are two Pressbooks online trainings that occur every month for users on hosted Pressbooks networks (includes UW):
Getting Started with Pressbooks
Advanced Pressbooks Publishing
The UW Libraries also offers occasional Pressbooks workshops or events. These are typically publicized through the UW Libraries calendar and the Pressbooks users email list.
UW Bothell library staff are available to consult with you about using Pressbooks, and to help if you get stuck. Please email uwblds@uw.edu if you have questions or would like to meet for one-on-one assistance.
