Some archives for the Provincial Council are stored in the Glenbow Museum in Calgary for the early years of the League until 1985. The link will take you directly to the archives and you can search for interesting information.
The remainder to the most recent archives are stored at the Alberta Provincial Archives from about 1960s to present. The link will take you to page 10 in the Provincial Council archive list, and you can then search in either direction! If you would like to see a particular article, you will have to visit the archives in person.
The procedure to access the Provincial Archives is to visit the reading room and ask for the items you wish to see.\
