Standard shelf mark used for non-Danish books
Augustinus Steuchus Eugubinus: De perenni philosophia (1542).
Here the Filos. shelf mark is seen together with two other significant marks: a number representing the first cataloguing of the Royal Library in the early 1660s and a later stamp reading Bibliotheca Regia Hafniensis (The Royal Library of Copenhagen).
Cf. the Shelf marks and ownership marks of the Royal Library page.
