Before there was a nation, there were printed traces. Volume IV of Charles Evans's monumental American bibliography gathers those traces with a curator's care and a historian's nerve. Names, dates, places, printed voices. Built as a chronological bibliographical dictionary, this volume maps United States imprints 1639-1820 through the lived reality of paper: books, pamphlets, and serials recorded with bibliographical and biographical notes. It is a library reference catalog you can browse like a time machine, following how ideas travelled between ports, towns, presses, and parishes. For anyone drawn to early American printing history, colonial era publications, or the shifting concerns of colonial America 17th century through the early republic, Evans offers a clear path through a vast, easily lost landscape. Researchers will value it as an academic research sourcebook; collectors will recognise it as a practical rare book collector guide, rooted in evidence rather than folklore. More than a title list, it is a lens on the history of American publishing: what was printed, when, and by whom, with the book trade and printers emerging as active shapers of public life. Use it to verify a citation, trace a family name, or explore a pamphlets and periodicals index that reveals the argumentative, urgent texture of the past. Republished by Alpha Editions in a careful modern edition, this volume preserves the spirit of the original while making it effortless to enjoy today - a heritage title prepared for readers and collectors alike.
