For anyone living in the Guelph area, the University library has a Scottish Collection (the largest outside of Scotland!). One of the little known gems in the library is the newspaper collection. From their spec sheet:
"Runs of older Scottish newspapers are held by the library, many of which are located in Archival and Special Collections. There is a rare file of the Glasgow Argus and the longest run in existence from 1774 to 1814 of the Edinburgh Advertiser, in its day Scotland's most influential newspaper. Periodicals such as the Edinburgh Review, the Scots Magazine and a complete run of the Celtic Magazine are located on the second floor of the library as are microfilm holdings of newspapers such as the Dumfries and Galloway Standard and Advertiser from 1777 to 1880 and the Glasgow Herald from 1830 to 1869."
Certainly worth a look.
