Carl Gustaf Warmholtz (1713–1785)[1] was a Swedish scholar, historian, writer, and a collector of historical books and manuscripts.
[2] A large bibliography of books and texts concerning Sweden is his main work still widely used and "remains the first place to look for Swedish imprints published before 1774".
He served as a secretary of the governments in Ypres (Flanders) and created links with prominent scholars in the Dutch Republic, Germany and other countries.
[4] Warmholtz, who before his homecoming translated to French Nordberg's King Carl XII's History (1742),[5] began early and continued until his death with eagerness to collect, organize, read and review all accessible deposits and foreign printed works and manuscripts concerning Swedish political, ecclesiastical, scholarly, legal and natural history, geography and more.
Following the pattern of Father Jacques Lelong's Bibliothèque historique de la France (1719), Warmholtz prepared a large bibliography of prints and manuscripts concerning Sweden printed as Bibliotheca historica sueo-gothica; eller förtekning uppå så väl trykte, som handskrifne böcker, tractater och skrifter, hvilka handla om svenska historien, eller därutinnan kunna gifva ljus; med critiska och historiska anmärkningar [Bibliography of Swedish history, a listing of manuscripts, printed books, treatises and writings on Swedish history] (15 volumes, 1782–1817, reprinted Copenhagen 1966-68), including 9,744 works of importance.
