Fonds consists of a wide variety of materials collected or created by Dr. Greg MacLeod, mostly written documents, but also videos and cassette tapes, many of which have been digitized. The written documents cover a wide range of genres such as correspondence, memos, financial reports, updates, feasibility studies, newspaper clippings, and minutes of meetings. These records have a date range beginning in the 1950's when Dr. MacLeod was in school in Sydney Mines (though there is one family document from 1899) and ending around 2004. The range of materials found here derives from his association with a number of organizations starting in the early 1970's, many of which he played a founding influence, such as Metropolitan Alliance For Development, Cape Breton School of Crafts, Island Housing Association, and the Cape Breton Association for Co Op Development, which itself would morph into New Dawn Enterprises. His social-economic interests continued with his involvement in the Tompkins Institute from its founding in 1974 and his close association with the university's Centre for Community Economic Development from its founding in 1986. Another large set of documents involves the founding of BCA Group in 1989 and its progress, and the various projects that were supported by it. Based on these associations, the fonds is arranged with the following series: Tompkins Institute; BCA Group; Centre for Community Economic Development, Audio Files, Video Files, New Dawn Enterprises, Economic Reports and Studies, and Autobiographical Materials. Each of these series (and some contain sub-series) will be composed of multiple files (some files with multiple folios) with each file containing many individual items.
