[3 updates below] A quick informational note apropos of my previous post.*
In addition to the email-writing campaign and the various petitions that have been circulating re: the Salaita case, there is an initiative, begun by Corey Robin (see here), to organize groups of scholars by discipline who would commit to refusing to make any visits to the University of Illinois Urbana-Champaign campus until such time as Professor Salaita's appointment was reinstated.
So far, this effort has borne fruit among philosophers (organized by John Protevi, here) and political scientists (organized by Joe Lowndes, for info see here). Those with appropriate disciplinary affiliations who are inclined to participate in these initiatives should contact the organizers, as noted. Those in other disciplines who are willing to organize their own list should contact Professor Robin, as detailed here.
Update: A statement by professors of English is being managed by Elaine Freedgood (info here.)
Update 2: A statement by professors of Sociology is being organized as a petition and a statement by professors of Rhetoric and Composition is being managed by Matthew Abraham (info on both can be found in this post on Corey Robin's site).
Update 3: There is now a statement of refusal for faculty in women’s studies, gender studies, and feminist studies being managed by Barbara Winslow and a general statement that is not limited to scholars in any particular field (info on both can be found here.)
