The Rev. Christine Robinson, First Unitarian Church of Albuquerque, N.Mex., has created a “multisite bibliography” for congregations interested in exploring the world of multiple-site churches. Read it on her blog, iMinister. Resources listed include news articles from the popular press and Christian publications as well as books.
There is also a UUA-sponsored email list, Multisite-UU, and an InterConnections article, Multisite Ministry Another Way to Grow and Serve. Both First Unitarian and First UU Church in San Diego have multisite ministries.
