In the spirit of its new policy of openness (“Hermetically open”), the Bibliotheca Philosophica Hermetica has posted a video on its YouTube channel that contains a 53-minute tour of the library’s collection, given by the founder Joost Ritman himself. This gives an excellent opportunity for non-Amsterdammers to have a peak at what the BPH looks like, and what the collection contains. But more than that, it gives an interesting insight into the mind of Ritman himself. As he guides online viewers through parts of his collection, we get to know quite a bit about how Ritman conceives of his collection, what it means to him, and what he has been trying to achieve with the library from the beginning. Worth checking out if you are curious about this legendary library and its founder.
