Join us as we edit and create Wikipedia pages related to Black history, with a focus on Black Cantabrigians. We will use resources from the Library's Archives and Special Collections and the Black Voices Collection at the Central Square Branch. At this Wikipedia edit-a-thon, we'll work together to contribute to Wikipedia, focusing on expanding our knowledge of underrepresented groups. You might add to the information on an existing page, create a new one, find reliable sources for others to use, or copyedit and format a page. All experience levels welcome! You do not need to have experience editing Wikipedia to attend and contribute! Laptops will be provided. If you have a Wikipedia account and want to join our dashboard for this event, please do so at this link: https://outreachdashboard.wmflabs.org/courses/Cambridge_Public_Library/Wikipedia_Highlights_Black_Cambridge_(February_25_2026) This event is in partnership with the Cambridge Black History Project.

The climate is changing, and we're all here on the planet together. Join us for a monthly community gathering and discussion of a variety of books about climate change. We will share thoughts, resources, and occasionally host special guests in a welcoming small-group environment. For our March meeting, we will discuss Human Nature: nine ways to feel about our changing planet by Kate Marvel (this book was originally our January read, but the discussion was cancelled due to weather). Copies of the print book are available at the Main Library Q&A Desk. The e-book and e-audiobook are available immediately on the Hoopla app. Registration is required. Please contact alengel@cambridgema.gov with questions.
