This set of tables comprises logarithms of numbers, both plane and logarithmic trigonometry tables and a collection of miscellaneous tables useful in navigation. The publishing firm started by Joannes van Keulen was active in Amsterdam for over two centuries. It specialized in maps, charts, pilot guides, and the like. The firm used the imprint of Joannes van Keulen and Zoonen in the second half of the eighteenth century (1756-1799).

From the recently dispersed library of Erwin Tomash (1921-2012), American engineer recognised for his early pioneering work with computer equipment peripherals. His library consisted of over 3,000 books and manuscripts relevant to the history of computation, from medieval and renaissance works on arithmetic, finger-reckoning and the abacus, to the birth in the twentieth century of theoretical and practical computer science under Alan Turing.
