 The Unitarian Universalist Association

200px-UUA_Logo.svgThe Unitarian Universalist Association of Congregations represents the consolidation of two American religious traditions, Unitarianism and Universalism, which joined in 1961 to become Unitarian Universalism. The UUA supports the member congregations, and is also the major source of funding for the Harvard Square Library. We are particularly grateful to the Frank and Alice Schulman Fund for the Schulman family’s support of HSL.

First Parish in Cambridge, Unitarian Universalist

firstparishThe Harvard Square Library is institutionally connected to the First Parish in Cambridge, Unitarian Universalist, from which we derive our “Harvard Square” name. Like the Cambridge Forum, we report to the First Parish, but are independent from it. For more on this connection, see  About HSL.


Unitarian Universalist History and Heritage Society

The Unitarian Universalist History and Heritage Society “aims to strengthen a community dedicated to the disciplined study of liberal religious history, and to advance education, research, and dissemination of our Unitarian and Universalist heritage within and beyond the Unitarian Universalist Association.”  They “promote the collection and preservation of historical materials, support research by academic and independent scholars, including those in Unitarian Universalist theological schools, disseminate the fruits of that scholarship through various media including the Society’s journal, sponsor events for a broad public, and engage Unitarian Universalist congregations in historical research and celebration of our heritage.”

UU RE HistoryThe Unitarian Universalist Religious Education History group encourages the study of the history of liberal religious education, especially among the Unitarians and Universalists.



The Universalist Heritage Foundation is “intent on developing programs that will articulate and spread this Universalist message, adding strength, depth and wisdom to contemporary Unitarian Universalism. This faith is a gift we want to share with the next generations and with the world at large.
