BOSTON (AP) — Two colleges in Boston are marking the end of Women’s History Month with an open event to update and enhance the Wikipedia entries of several female activists.

“Digitizing Women’s History: Wikipedia Edit-a-thon” is being hosted by Simmons University and Wentworth Institute of Technology on Tuesday.

The event is part of the Digitizing Women’s History series that marks the 100th anniversary of the ratification of the 19th Amendment, which prohibited voter discrimination based on sex.

Participants can help make women’s history more visible on the internet by writing and editing Wikipedia entries, particularly those of suffrage and civil rights activists and women of color.
