Dalhousie Libraries’ University Archives Online Collections

Halifax's Dalhousie Libraries’ University Archives has digitized the university yearbooks and calendars.
The yearbook collection, available as pdfs for browsing and searching, runs from 1927 to 1975. If you or a family member graduated from Dal you'll likely find them there, with a photo.
Calendars are from 1855/56 to 1950/51, also as pdfs
Also online as pdfs is the entire archive of Dalhousie Gazette, one of North America’s oldest student newspapers.
Looking for a name? It appears that while you can search across the entire corpus of each collection you need to download the issue identified and then search it using the pdf search.
There are a few other collections, view the list at http://dalspace.library.dal.ca/handle/10222/11480
