The Charleston Conference is an informal annual gathering of librarians, publishers, electronic resource managers, consultants, and vendors of library materials in Charleston, SC, in November, to discuss issues of importance to them all. It is designed to be a collegial gathering of individuals from different areas who discuss the same issues in a non-threatening, friendly, and highly informal environment. Presidents of companies discuss and debate with library directors, acquisitions librarians, reference librarians, serials librarians, collection development librarians, and many, many others. Begun in 1980, the Charleston Conference has grown from 20 participants in 1980 to over 1,400 in 2011. Proceedings of the conference published since 2009 are made openly accessible through the support of Purdue University Libraries, the parent organization of Purdue University Press, a unit of the Libraries.
