Join Professors Daniela Melo and Timothy Walker, the co-editors of a new scholarly edition of legendary Australian journalist Wilfred Burchett’s writing on the Portuguese “Carnation” Revolution, in a discussion of this new edition-- published in English for the first-time (Verso Books, UK). Melo and Walker will discuss how Burchett’s reporting sought to demonstrate the power and strength of popular mobilizations during the Revolution, shifting the focus away from political elites toward mobilized citizens. Burchett's analysis on the roles of political elites, economic elites, and mobilization provides rich insights, revealing the types of networks and interactions between these actors, and the roles that narrative, storytelling, and emotions played in the making of the Portuguese Revolution. This event is cosponsored by the Consul General of Portugal in Boston and the Cambridge Public Library. Registration is required.

What happens when mental illness meets homelessness and there’s nowhere to turn? What does healthcare look like when you’re sleeping outside, alone, and invisible? Join NAMI Cambridge/Middlesex and the Cambridge Public Library for an unflinching look at healthcare on the margins as Dr. Jim O’Connell, founding physician and President of Boston Health Care for the Homeless Program (BHCHP) shares stories, insights, and hard truths from a lifetime spent caring for patients—not in pristine clinics but in shelters, on sidewalks, and under bridges. Moderated by Dr. Rich Parker, this one-night event will explore the barriers so many in our community face when mental illness goes untreated, housing is out of reach, and support feels out of sight. Cosponsored by Cambridge Public Library. Registration is required.

Trash is collected weekly.
