Temple University will serve as the headquarters for service projects happening around the tri-state area for the 31st annual Greater Philadelphia Martin Luther King Day of Service.

Philadelphia Mayor Cherelle Parker will be joined Monday morning by local leaders, including Pennsylvania Governor Josh Shapiro.

They’ll help out with the signature project of assembling what they call “Book Arks,” self-standing structures that will offer free books to organizations in local and underserved communities.

Every year, there’s a regional signature project led by thousands of volunteers from Philadelphia, New Jersey, and Delaware.

They will be honoring Dr. King’s legacy of social justice by transforming this national holiday into a day where the everyday person takes action.

Events like this will be held across the tri-state area, tying into the overarching theme this year of highlighting Dr. King’s commitment to civil rights through equity in education.

The opening ceremony begins at 9 a.m. at Pearson and McGonigle Hall, followed by free events for the public that include workshops, a kids carnival, a health and wellness fair, and a jobs and opportunity fair.
