School books, agricultural literature and local history works made up the publishing program.
In 1964, Walter Georg Olms acquired the publishing houses M. & H. Marcus (formerly Breslau) and Academia Verlag, Prague.
From 1969, works of trivial literature, fairy tales and legends, hippology, film history, culinary art and mail order catalogs were published under the name Olms Presse.
Since the founding of Georg Olms Verlag GmbH in 1973 and Georg Olms AG in Zürich in 1980 with its subsidiary founded in Hildesheim in 1982, the publishing program has included not only first publications but also reprints of scientific literature on humanities and on the history of medicine, natural sciences and technology.
With the mass catalogs (1594–1860) and 350 volumes from the reprint program, editions of works by the Brothers Grimm, Johann Gottfried Herder and Christian Wolff are also available digitally.
