University of Guelph Scottish Studies Collections

No matter how obscure a collection mentioned here often someone finds it of interest. Hopefully that will be the case with this collection of 406 volumes digitized and online at the Internet Archive.
As modestly described on the website:

The University of Guelph’s Scottish collection is one of the finest in the world. Interest in building Scottish and Scottish-Canadian holdings began after 1965 when the University of Guelph was established. Over the years, the Library has established rare book, manuscript, and archival resources which have gained national recognition. Among the monographic holdings there are numerous guidebooks and travel accounts and local histories relating to all areas of Scotland that contain fascinating pictorial records.

 58 of the volumes are given a genealogy tag.
