Here's a few in my personal library.
--The Writer's Guide to EVERDAY LIFE FROM PROHIBITION THROUGH WORLD WAR II, by Marc McCutcheon, printed 1995 by Writer's Digest Books.
--The Writer's Guide to EVERYDAY LIFE IN THE WILD WEST FROM 1840-1900, by Candy Moulton, printed 1999 by Writer's Digest Books.
--The Writer's Guide to EVERYDAY LIFE IN THE 1800S, by Marc McCutcheon, printed 1990 by Writer's Digest Books.
--EVERYDAY LIFE DURING THE CIVIL WAR A Gude For Writers, Students and Historians, by Hichael J. Varhola, printed 1999 by Writer's Digest Books.
These books contain the minute information of everyday life during the subject periods. The slang, idiosyncrasies, the small details of life and the historical specifics that a writer of fiction OR history would need to know to make his/her story / book as authentic as possible.
Go to the on-line libraries such as,
The Online Books Page and search for books dealing with your area of interests.......especially personal diaries. On this University of Pennsylvania site, I found the travelers' guide to the Oregon Trail that gave the daily milages to the specific campgrounds and directions from campsite to campsite, from beginning to end. Now, just think what a good (or even a half-assed) metal detectorist might find along that trail, especially at the campgrounds and waterholes. Another book at this website, is the diaries of Marcy's travels throughout the west / southwest.
This one site is an excellent source of copies of original books and pamplets that you can download for free.
