Book info: Philip A. Harland. Associations, Synagogues, and Congregations: Claiming a Place in Ancient Mediterranean Society. Second revised edition with links to inscriptions. Kitchener, Ontario: Philip A. Harland, 2013. <http://www.philipharland.com/associations/>
The main advantage of this edition is that each of the inscriptions and sources mentioned is keyed to the new Associations in the Greco-Roman World sourcebook and there are direct, clickable links in the pdf to the corresponding inscription on the AGRW companion website (found here: http://philipharland.com/greco-roman-associations/ …). You simply click on an inscription number (e.g. IEph 1503) in the pdf and are brought to the description, Greek text, and a translation. There are also many, many new illustrations and figures (many in color).
Definitely worth checking out, even if you’ve explored it previously!
