How do I find OPL books that I have commented upon ?
Thanks for asking! It doesn't appear that our Bibliocommons catalog offers a way for a user to review their own comments, or search by comments. To at least winnow down the field, though, the catalog's default behavior is to add every book you've commented on to your completed shelf. Depending on how heavily you use your Shelves, you may be able to find material you've commented on that way.
Thanks for using AskOPL!
