I've just joined the site, so I don't know if anyone else has posted this info, but there are loads of public domain books about Glasgow at
http://archive.org/search.php?query=%28 ... 28texts%29
There is even an extensive set of Glasgow Post Office Directories ranging from the early 19th century to well into the 20th.
I would recommend downloading the DjVu format of the books, as they only take up about 10% of the space of the PDF files. You can download a free DjVu viewer at
http://windjview.sourceforge.net/
I don't recommend the Kindle versions, as many are so badly formatted as to be virtually unreadable.
Here are some of the books I've downloaded from the site over the years:
