The HTA collection comprises a variety of records, with an emphasis on correspondence and papers relating to the activities of the Harris Tweed Association (1909-1993) and the Harris Tweed Authority (1993-present). It is arranged into nine subfonds. Some parts of the catalogue exist to item level, while other parts are available only to subseries.
GD014/1, Administrative, contains founding documents and the minutes of the Committee of Management and later the Board of Directors, as well as the minutes of other committees and groups involving the HTA, and papers relating to its facilities and staff.
GD014/2, Financial, contains account books and ledgers, and more recent accounts, financial statements and tax information.
GD014/3, Correspondence, reports and papers, is one of the largest subfonds. It consists of correspondence, reports and papers relating to the main activities that the HTA is involved in - protecting the Harris Tweed trade mark, liaising with the rest of the industry, and promoting Harris Tweed, as well as correspondence with funding organisations and individuals.
GD014/4, Harris Tweed court case (1961-1964), is the largest subfonds, and contains material produced or gathered in the course of the case in the Court of Session in Edinburgh before Lord Hunter. Since a vast volume of evidence was collected for the case, this section is particularly useful for researching the industry in the first half of the 20th century.
GD014/5, Industry, contains records produced by the different component parts of the industry, from role of the HTA in stamping the cloth, to the weavers, mills, and retailers and designers who make products from the fabric.
GD014/6, Marketing and promotion, consists of material produced in the course of the HTA's promotion of Harris Tweed. It includes leaflets, point-of-sale boards and limericks, as well as marketing reports and plans for a visitor centre.
GD014/7, Media, illustrates the industry's portrayal in the media through press cuttings, magazine articles and a TV programme.
GD014/8, Education, art and research, shows how Harris Tweed has been used in a creative capacity, with school and college projects, photography, poetry and theatre represented, as well as drafts of Janet Hunter's history of the industry, 'The Islanders and the Orb'.
GD014/9, Photographic material, contains images of the industry, including many fashion images of Harris Tweed clothing, in a variety of formats.
Throughout the catalogue, the acronym HTA has been used to refer to both the Harris Tweed Association (1909-1993) and the Harris Tweed Authority (1993-present).
