This is "out there" for some people, but thework.com really is a version of CBT even though they wouldn't call it that. They have free worksheets and videos on how to do it.
I have actually found multiple free links to PDF copies of old CBT books from 2009. I was wondering if it would be illegal to distribute these links to patients?
This is good. And for the general stuff I have often googled "cognitive distortion worksheets," "anxiety hierarchies," and just have a folder with everything in it I have collected over the years.
Another good resource are public agency websites (and just emailing people there), MIRECC (VA), NIH/NIMH, NIAAA, NIDA, National Center for PTSD, etc.
I just googled CBT for psychosis and got some neat workbooks and an entire therapy manual from the MIRECC.
