There are over 275 Ottoman Turkish and Çaĝatay manuscripts in Canada, including more than 200 in the collection of Professor Eleazar Birnbaum. These are remarkable in terms of age (mostly 15th to 17th century) and subject range. The descriptions in this catalogue are unusually detailed: they include author, title, subject, contents, first and last words, date of manuscript, calligraphy, foliation, dimensions, and the location of similar manuscripts elsewhere. Among other special features are details of watermark designs in the paper (useful for dating undated manuscripts), descriptions of seals and notes of previous owners, and many colour illustrations. The catalogue also describes all Turkish manuscripts in the three other small Canadian collections: at the University of Toronto, McGill University (Montreal), and the Royal Ontario Museum.
