Scholarly groups have long served as hubs of academic life and the embodiments of their disciplines, but they face uncertain and divergent futures. Some disciplinary associations are struggling to remain relevant and financially viable as demographic and technological changes threaten their traditional sources of revenue. The core of their membership--tenured and, especially, tenure-track faculty--is shrinking and, in many cases, aging, with adjunct instructors now making up about two-thirds of the professoriate. Attendance at annual meetings is getting squeezed as the job market weakens, travel grows costlier, and colleges cut back on their support for professional development. Meanwhile, demands for open access through the Web are eating into revenue from scholarly journals. Economic realities, and quirks of history, mean some scholarly associations are well off. Others are on shaky financial footing.
