The fonds is comprised mostly of records pertaining to Maurice Zbriger's career as a musician and composer, including sheet music both used by Zbriger in practice, and composed by Zbriger himself, mostly ranging from the late 1910s through the 1950s. Likewise, the fonds contains several albums worth of vinyl and shellac records to which Zbriger contributed, typically as composer; while some of the records are commercial editions, many are first prints or one-offs. Additionally, some signage and pamphlets for concerts and performances can be found in the fonds, as well as newspaper clippings and signed documentation pertaining to a song's copyright.

The fonds also contains a number of photographs of Zbriger's family, friends, and collaborators. Many feature his wife, Mary Zbriger, or Maurice Zbriger with other musicians (including Erna Sack at CKAC); additionally, a small collection of musicians' portraits (some of whom were Zbrgier's collaborators) is included.

Finally, a number of Zbriger's personal documents, including a small amount of personal correspondence, notes, and memos, can be found in the fonds.
