I wasn't able to get to the webinar today, but I did want to follow up on the email Federico Leva sent earlier today. As an update on the project mentioned in that email: Librarians at Penn are now researching status and free issue availability of periodicals and other serials held by Penn. As a result, many of the Deep Backfile tables linked from the discussion are being filled in considerably more quickly than before, as you can see at https://onlinebooks.library.upenn.edu/webbin/backfile/ (Indeed, we're currently getting information more quickly than I can verify it and turn it into Wikidata-linked data records, which is why you'll see numerous occurrences of "Pending" in some of the tables while we try to catch up.) Once information on a serial is supplied in one of the tables, it's also automatically filled in on any other table listing the serial. We continue to welcome outside participation, and can consider creating tables for other sets of serials as well. If you're interested or have questions, please feel free to get in touch.
