A wide range of types of research materials are used by the arts/humanities community, based on the planning wiki notes. Various terms are synonymous with the term research materials, including data, information, resources, content, etc. This theme serves to outline some types of materials that are the objects of various scholarly activities undertaken against those materials, which are outlined in several other themes.
These types of materials are also represented in a variety of formats, media, or representations. Some of the themes center on transformations between the various formats, media or representations (such as digitizing).
Aggregations of research materials or of metadata about research materials may also be considered as objects of research activities, such as collections, exhibitions, catalogs, finding aids and the like.
The Minnesota study (A Multi-Dimensional Framework for Academic Support: A Final Report, http://www.lib.umn.edu/about/mellon/UMN_Multi-dimensional_Framework_Final_Report.pdf., page 39 gives a good summary: "Given the wide array of material used by scholars in a single project or over the course of a career, these materials range from books and articles, electronic resources, film, sound recordings, artifacts, data sets, ephemera, maps, and more."
