The Université du Québec à Montreal has published an important online bibliography of books, articles, and theses about the history of Montreal that contains 9,684 titles in English and French. If your ancestors lived in Montreal, you must explore this bibliography.
This digital bibliography is the result of bringing together two major works: Clés pour l’histoire de Montréal, a bibliography of almost 4,000 titles, published for Montreal’s 350th anniversay; and the quarterly, Revue d’histoire de l’Amérique française, that publishes bibliographies of theses written in Quebec universities.

The Université du Québec à Montreal’s online bibliography contains almost 10,000 titles about the history of Montreal.
Although the website is in French as are many of the titles, it is relatively easy to find English documents through keyword searches and the filters.
Keyword search
To find a document, try the keyword search box — Mots clés — at the top of the filters column in the left margin. Type in a word or series of words and click on Rechercher (Search). Irish, for example, will produce a long list of publications that are in English.

A search in the Université du Québec à Montréal’s online bibliography uncovered the title of this book, and a Google search found the book on Internet Archive.
Entering Grand Trunk provided a list of documents about the Grand Trunk Railway, including A History of the Grand Trunk Railway of Canada, a 62-page booklet published in 1864. In this case, I Googled the book title and author and found an online copy on Internet Archive that I can read.
Another search I tried was Molson to see if any books about the Molson brewery family are listed in the bibliography. Twelve titles appeared.

Thanks to Janice Hamilton for sharing this bibliography with me. Ms. Hamilton writes about her ancestors in her blog, Writing Up the Ancestors.
That looks fascinating. I could get lost in there for hours. Thanks for sharing! I’ve included this post in my NoteWorthy Reads post for this week, too: http://jahcmft.blogspot.com/2015/05/noteworthy-reads-15.html
