The Library has the first atlas with the first Czech map of Bohemia. This is in the 1545 Muenster edition of Ptolemy's Geographia. It also has the first independent map of Moravia (Fabricius, 1568), which appears in Ortelius' Theatrum orbis terrarum (Antwerp, 1570), and the first Ortelius atlas with Lazius and Sambucus maps showing Slovakia (1579).
A particularly precious item in the Library's collection is Augustin Herman's extremely rare map of Virginia and Maryland of 1670, which was acquired in 1960.

Herman's map was entitled Virginia and Maryland as it is planted and inhabited this present year 1670 surveyed and exactly drawne by the only labour & endeavor of Augustine Herrman bohemiensis.
