Apparently the Bibliotheca Corviniana Digitalis , an up to now partially completed attempt at a "Virtual reconstruction of King Matthias' Library", has/had not yet been mentioned on this forum here. Sorry about that!

A list of digitised and not (yet) digitised known items can be found at http://www.corvina.oszk.hu/corvinas-html/corvinas.htm .

Let me single out just one of these items: The Florence Laurenziana (Plut. 73. 39) copy of Marsilio Ficino's De triplici vita sive De vita libri tres (not (yet) digitised).

n ambitious project aimed at the virtual reconstruction of the library has been started by the Széchényi National Library (Budapest). The Digital Corvina Library aims to gather all information and digital facsimiles of all of the surviving volumes from the library of King Matthias. Unfortunately, the site apparently has not been updated in several years. It now includes the digital facsimiles of all 36 Corvinian manuscripts held at the National Library. Below you can find direct links to these, as well as to an additional 62 fully digitized Corvinian manuscripts, as well as to many additional images. Further information and bibliography is available on the Bibliotheca Corviniana Digitalis site.
