Wikipedia
The Wikipedia community encourages experts in the cultural heritage community to edit, enhance, and create Wikipedia articles,[1] and the Folger Shakespeare Library welcomes this opportunity. Guided by resources from the GLAM-Wiki initiative ("galleries, libraries, archives, and museums" working with Wikipedia), Folger staff edit Wikipedia to improve access to information about Shakespeare and the early modern age in the West in keeping with Wikipedia's fundamental principles, known as the Five pillars.
