Please note that abstracts cannot be accepted before October 25th 2011. Seventh Joint Meeting of the BSHS, CSHPS, and HSS The seventh joint meeting of the British Society for the History of Science, the Canadian Society for the History and Philosophy of Science, and the History of Science Society will take place in Philadelphia, Pennsylvania, USA from 10-13 July 2012. Previous successful meetings were in Oxford, England (2008); Halifax, Nova Scotia (2004); St Louis, Missouri (2000); Edinburgh, Scotland (1996); Toronto, Canada (1992); and Manchester, England (1988). Unlike some three-society meetings in the past, the 2012 conference has no stated theme; papers on all topics in the history of science are welcome. As 2012 marks the centennial of Isis, papers related to the history of both Isis and/or the discipline would be timely. The Philadelphia Area Center for the History of Science (PACHS) is helping with the arrangements. Dorm room accommodations will be available at the University of Pennsylvania, and a small number of hotel rooms will be reserved for the conference (individuals will need to call the hotel directly or visit the HSS website, hssonline.org, for reservations). The program will include parallel themed sessions, plenary lectures, education and outreach activities, and events at the American Philosophical Society, the Chemical Heritage Foundation, and the University of Pennsylvania. A more extensive social program is being developed by the local organizers. The conference schedule will offer delegates the opportunity to explore the many attractions to be found in the "City of Brotherly Love," including Philadelphia's extensive links to the history of science. The Program Committee welcomes proposals for sessions or individual papers from researchers at all stages of their careers. Participation is in no way limited to members of the three organizing societies, but there will be a registration discount for members. Intending participants should also note that the usual HSS rules concerning presenting at successive conferences do not apply to this meeting. Online abstract submissions will open on 25 October 2011. The deadline for submitting a session or abstract is 5 December 2011. Full details of how to submit your session or abstract will be available shortly on the HSS website at hssonline.org. Inquiries concerning this conference should be directed to [log in to unmask]
