Best sources for a deep dive into OCD

I hope this post is not out of bounds. I am trying to get more information to determine if my mood disorder is indeed OCD. I have been misdiagnosed so many times by so many psychiatrists over the years and really want to find some good, solid sources, outside of the "stereotypical" descriptions of OCD. I am meeting with two psychiatrists this week and hope to be armed with some good information.

I have been diagnosed with treatment resistant depression for over the past 13 years.
