In honor of Ada Lovelace Day, a global celebration of women’s contributions to STEM, we are hosting an edit-a-thon to improve Wikipedia and Wikidata’s representation of women and LGBTQ+ people in STEM fields.  We will provide tutorials and instruction on how to edit Wikipedia & Wikidata—no previous experience necessary! This is a drop-in event, so you can come and go as you are able. Snacks will be provided.
