Csapodi Csaba: A Magyar Tudományos Akadémia Könyvtárának ősnyomtatvány-gyűjteménye (A MTAK kiadványai 53. Budapest, 1967)

The characteristics of the incunabula collection come from the nature of their origin: their greater part was brought together as a result of the collecting activity of private persons and came into possession of the Library as their gifts. Since the collectors could obtain such old books from foreign second-hand dealers only, the number of books which are likely to have been in Hungary as early as the fifteenth century, is comparatively small. It is for the same reason that the Library has a number of incunabula in more than one copy: there are 112 incunabula in two, 13 in three and; 4 in four copies. On the other hand, it is also due to this kind of purposeful collecting activity of György Ráth and Count Ferenc Vigyázó that the collection is exceedingly rich in old printed books relating to Hungary. About one-fourth of the collection consist of such books: works by Pelbartus de Temesvár, Osvaldus de Laskó, Michael de Hungaria, Simon de Hungaria, Georgius de Huingaria, Iohannes de Thurócz works dedicated to King Matthias Corvinus and to Hungarian humanist, works on the struggle against the Turks, Hungarian ritual books, and publications of printers of Hungarian origin. The supplement at the end of the study contains statistical charts and tables giving various information on the incunabula: language, place and date of publication, content, list of towns in which most incunabula of the collection were published, list of most important printing offices, unique copies, and finally the titles of three incunabula which are not unique but the most complete copies known. 24
