Soo I really only have bits and pieces of cataloging down at this point as I’ve mostly learned through watching other people, I’m just weirdly eager to learn more. My actual cataloging course will be in the winter semester and we’re supposed to have a great RDA guy teach it. I’m always happy to pass on our resources then. If you’re looking for stuff now, the best I can do is offer these resources that I’ve browsed through and that I know my cataloging expert (my mom haha) has used to refresh:
1. LOC RDA training materials, which is a LOT to go through but has presentations, worksheets, quizzes, etc. http://www.loc.gov/catworkshop/RDA%20training%20materials/index.html
2. RDA Toolkit online for the rules/specifics, which sadly requires a subscription, but perhaps a friend or institution has subscribed?
3. Adam Schiff’s website has really useful AACR2/RDA comparison slides, and lots of them. I learn new things best when I have examples to look at, so this is helpful for me: http://faculty.washington.edu/aschiff/
If anyone else has something to share, please add!
