I’ve been recently informed about some really great professional development resources put together by the AASLH’s Professional Development committee that you’ll want to check out.
Basic overview is here: Careers for History Professionals
They also link to a great white paper called Museum Careers: Fit, Readiness, and Development. Presumably since you’re part of the Tufts community you already have an idea about the fit – but this paper does a good idea of presenting the realities of the museum job world and making suggestions about a way forward. It’s also current to early 2011, so apropos for the current economic climate.
