I've only looked at it once, but it seemed like tedious reading.

If you haven't tried them, many people like "TheTaxBook" or "Quickfinder" for referencing things (both are similar, but I think many people prefer TheTaxBook).  But becoming proficient at Googling things works well too.

If you are interested in purchasing TheTaxBook, they also have an online version that may be handy.  If you want to try NATP for your continuing education, the "Premium" membership (which is most useful if your primary source of continuing education is NATP) also comes with the online version of TheTaxBook as part of the membership.
