Highlight of the day was getting a thank you from a faculty member for a reference question I answered three odd years ago on the topics of sidepaths. There was chocolate (!) and the best part, a copy of the published article.
Just told our outreach librarian that she can have a couple hundred bucks to promote open access week this fall. She and our metadata librarian are going to have temp tattoos made of the OA logo, and do a "the price is wrong" game/raffle to see who can guess the cost of a single article from a random expensive traditional journal.
