AcMeS aims to be discipline independent. But historically AcMeS has grown out of the RePEc project. RePEc is three things at once. First it is a collection of servers that provide structured data about electronic and printed documents in economics. These data mainly, but not exclusively, point to working papers.
Some servers also make the full text of the papers available.
Others contain URLs for the papers from another site. Others have no option to downloads papers. The collection of these servers make up the first aspect of RePEc. Secondly the term RePEc also designates the group of people that provide these servers. This is a mixed group comprising academics, departmental computing support staff, librarians and other volunteers.
