Since August 2017 I have been collecting material on the Romans in Scotland. Here are some of the resources you can use to do your own.

National Library of Scotland Digital Resources – Sign up for an online account and searches thousands of scholarly articles on Romans. It’s a bit technical but a rich resource that I have been using for 15 years.
Archaeopress – has free books and articles on Romans called “open access”. In addition to the Open Access titles, over 150 titles are available as free-to-download PDFs for personal use
National Library of Scotland Digital Maps – Nearly every map of Scotland digital and online for you to look at. Roman roads and camps are frequently mapped. The guy who leads this, Chris Fleet, is one of the unsung heroes of Scotland creating this fabulous site that just works. He didi it on a shoestring budget too.
