The fonds documents Sharon Thesen’s personal and professional life as a poet, editor, and professor from 1961 to 1989. All records in the fonds were collected by Thesen herself, and are primarily composed of correspondence, journals, and creative work. Most of the creative work is composed of drafts and edited versions of Thesen’s own poetry, essays, and articles, but also includes work sent to her for review. While most of the records are textual, there are a small number of pictures and postcards that were sent to and taken by Thesen, and are mostly of a personal nature. Notably, a large section of the fonds is made up of letters that include correspondence between other published and acclaimed authors such as Michael Ondaatje, Christopher Dewdney, Lola Lemire Tostevin, Ken Norris, Judith Fitzgerald, Phyllis Webb, Gerald Burns, and others. Lastly, the fonds also includes Thesen’s journals from the mid-60s to the mid-80s which contain her daily activities, her personal thoughts, as well as some of her creative work.
The fonds is arranged into three different series, Chronological Files, Journals, and Personal & Professional Records, as per the internal organization of the records. The main forms of these records are textual records, but also include graphic/photographic materials and mixed media. The records are arranged chronologically and intellectually within the series.

Fonds reflects L.-G. Papineau's daily work as an engineer between the years 1901 and 1905. Each volume is a daily diary, covering a year. Daily entries describe the activities of the people in his office. Most entries are technical: daily follow-ups on public works projects, including in the Montreal and Sorel harbours, Hochelaga, and on the Saint-Pierre River, meetings, finished tasks, and the absence of workers. Some are family related or comments on the news (for example, Queen Victoria's funeral on February 4th. 1901). Weather conditions and water levels are reported regularly, as it influences the pace of work on the construction sites.
