This series comprises annotated publications, notes and notecards, and typed and handwritten drafts for books and articles. A partial copy of Bartroli’s master’s thesis and his contributions to a proposal for the development of Nootka Sound as a historical site are included. Some book drafts and chapters do not have identifiable titles or dates.

This series includes newsletters, programs, newspaper clippings, and flyers that promote lectures and talks Bartroli gave. He spoke for a variety of academic and community organizations on European exploration in the Pacific Northwest, the politics and culture of Spanish-speaking countries, literature, and travel. Also included are correspondence, minutes, and promotional material for UBC’s Spanish club El Circulo, as Bartroli was a faculty member and frequent speaker for the club.

This fonds primarily reflects Bartroli’s research interests in the early exploration and settlement of the Pacific Northwest by Spain. Research materials include annotated articles, notes, and article and book drafts on the early Spanish presence in B.C. Drafts and notes from his books and articles also involve research and writing on the Northwest Coast's early British voyages and occupations. Notes and drafts from his research and writing on the Spanish language and Sancho Panza from Don Quixote, are included.

This fonds also contains correspondence, programs, clippings from his speaking engagements, newsletters, and administrative records from his time as a member of El Circulo, UBC’s Spanish club.
