Join the Cambridge YWCA, the Cambridge LGBTQ+ Commission, and the Central Square Branch Library for a screening of the short documentary Ephemera about Libby Bouvier's activist button collection. Libby Bouvier has spent most of her life collecting an archive of cause buttons and other "ephemera" from the women’s movement, the LGBT movement, and other radical causes she's been directly or indirectly involved with over the decades. This is a moving image portrait of her and her collection. Produced by Lily Bouvier. After the documentary screening, we'll have an opportunity to share about our own activism and to use the Library button makers. We'll have magazines, paper, markers, and more so you can make your own buttons to share your activism with the world! Get creative with us, and join other local activists!

In honor of National Public Health Week, please join us on Thursday, April 9th from 1-2:30 pm to volunteer to put together overdose prevention kits at the Cambridge Public Library, Central Square Branch. This year’s National Public Health Week theme "Ready. Set. Action!" calls on each of us to take part in community-driven solutions and daily actions that create healthier, more equitable, and connected communities. The You Can initiative (youcan.info) addresses overdose deaths by increasing access to lifesaving skills and resources statewide. Volunteers play a crucial role in this program by assembling the kits that are then mailed out across the state, getting lifesaving resources out to people and families who need them, free of cost. Each kit contains naloxone, fentanyl test strips, and other vital resources. Volunteers will be able to leave with a completed kit, if desired. Representatives from the Cambridge Health Department will also be onsite to provide additional resources and support. This program is a partnership between the Massachusetts Department of Public Health and Health Resources in Action (HRiA) and hosted by the Cambridge Health Department and Cambridge Public Library.

Join friends at the O'Neill Branch to build, build, BUILD! Let your imagination run wild with LEGOs, Magna-Tiles and other building toys.

LEGO pieces are choking hazards for young children.
