Primary Sources, Uncharted Americana is Robin Beck, PhD and Laoma Beck, MD. This year we are pleased to present our fourth catalogue. Whether manuscript diaries, ledgers, or letters, printed pamphlets and broadsides, photographs, or even actual books, they all contribute new ways of seeing and thinking about broader currents throughout American history. Our name is what they have in common. They are primary sources, and they are largely uncharted. So here are twenty-five new and sometimes unexpected items, all fresh to the trade. Thanks again to everyone who supported our earlier efforts, and we hope that you enjoy browsing Catalogue 4. We look forward to hearing from you.
