Good news for long-distance users of the Bibliotheca Philosophica Hermetica (Ritman Library) Amsterdam: from today the catalogue of modern and pre-1800 printed books is online. The catalogue can be accessed via the ‘SEARCH CATALOGUE’ button on the library's website. The catalogue has a number of search options, including author, title, year, printers, but also names of former owners. A guide to the library is now available entitled Hermetically open which considerably enhances the transparency of the collection. The guide informs the reader about the subjects he can expect to find in the library and about the relationship between the various collecting areas (Available in English and in Dutch, € 5). A new exhibition is now showing under the same title showing more than 80 printed books and manuscripts. Visitors to the library will find a new information corner, with instructive panels, which also offers a power point presentation showing a selection of some 100 images focussing on the printed books and manuscripts before 1800.
