If you haven't been following both the Wikipedia LIbrary and Wikiemdia Research have been working actively with Crossref to improve Wikipedia citations and to reach out to the publishers and OA communities in their network. 

They recently reached 80,000,000 records in their database, and are trying to find other instances of other instances of  80,000,000 in response to their tweet and using the hashtag at https://twitter.com/crossreforg/status/718352010291113984 . We responded for TWL at https://twitter.com/WikiLibrary/status/718488294028353537 . It would be great if we shared from Wikimedia accounts instances of 80,000,000 on our projects.

Cheers, 

Alex
