The cartographic works and maps in Isaac Vossius' collection consists of 188 loose map sheets, 24 printed atlases and 4 manuscript volumes. Based on the numbering on the back of the loose maps, three, incomplete sets of maps can be distinguished. The maps all date from the middle of the sixteenth century and most of them are printed in Venice and Rome. The first two sets can be considered as so-called 'IATO atlases' (Italian atlas assembled to order), also named 'Lafreri-atlases' after the Roman printer-publisher who was the first who sold maps bound together as a book. A considerable part of the non-Italian maps are printed in Vienna and various cities in Germany. The small third set consists of five plans of Rome. In the Vossius collection 24 printed books can be considered as atlases, an overview is given by De Vries (1981). The atlases date from 1507 to 1663. Ten of these atlases are published in Italy, among others the 1507 Ptolemy edition (Rome). Eight atlases are published in Amsterdam, among which several sea atlases. The other works are printed in Cologne, Ingolstadt, Strasbourg and London. Finally four manuscript works with maps in the Vossius collection are worth mentioning:

The 24 printed atlases and other geographical works are spread over the holdings of rare books and atlases of the library:
