Part of my historic anthropology project has included a lot of archival research to gain a better understanding of the 18th to mid 19th century mindset. From time to time, I encounter period booklets that are perfect for the frontier traveler's pocket. Here is a set of books I have developed over the last few years using paper materials that are the closest match to the original products I replicated.
In this photo are road maps, travel guides, almanacs, exchange rates, and prospecting guides from the 1840s-50s.
Travel Guide - Provides Routes, travel advice, list of equipment and supplies (weight and cost)
Almanacs - Allow travelers to know the correct dates/times to monitor their progress. It also provides statistics on Federal, State, and local government as well as useful Life Hacks.
The Coin Exchange Book - Allows the reader to identify the various Gold and Silver coins from around the world and know their worth in US coinage when accepting them in payment.
The Assay Book - Was commonly carried by prospectors during the California Gold Rush. It covers the full process of recovering, assaying and Grading gold.
