I'm researching the history of Scottish hotels and I'm trying to find out what guide books would have been most commonly used in the late 1960s - early 1970s in the U.S. for travelers to Scotland. Or what travel magazines would have been most read in the U.S. at that time.
I apologize for posting a research question to a travel advice site, but I figured that this is probably the best group of people to ask!
Thanks!
