Now I would like to call attention to another wonderful resource, the digitized manuscripts at the Biblioteca Medicea Laurenziana, Florence. You can read an overall description of the manuscript collection of the library here, while the following description of the digitization comes from the website of the project:
"The project foresees the complete digitization of 3,900 manuscripts belonging to the Plutei collection and of the 18th century catalogues which describe them. On conservation grounds it will be possible that a limited number of manuscripts will not not be digitized. The project is scheduled to finish by December 2010."
The library holds over 30 codices which were originally ordered by King Matthias. Many of these manuscripts were still unfinished at the time when news of the king's death reached Florence (1490). The volumes have been incorporated into the Medici collections. It seems that most of them were only fully decorated and finished for Pope Leo X, at around 1513. Most of these volumes were illustrated by Attavante degli Attavanti. These manuscripts thus never made it to the library at Buda - but colophons, dedicatory inscriptions and other data indicate that they were originally copied for Matthias. There are also a few other Corvinian manuscripts in the library, which got there at various points. Unfortunately the most important Corvinian manuscript in Florence, the three-volume Bible of King Matthias (Plut.15. 15-17), has not been digitized. Illuminated by the brothers Gherardo and Monte di Giovanni and by Attavante, the unfinished volumes entered the collection of Lorenzo de' Medici around 1490, just like the Marsilio Ficino volume illustrated below.

You can browse these beautiful manuscripts from the Corvinian library in the website of the Laurenziana library (the database requires Java to run). I am listing the digitized manuscripts which have been identified as intended for the Bibliotheca Corviniana (the list is based on the one compiled by the Bibliotheca Corviniana Digitalis project):
Plut.12.09; Plut.12.10; Plut.13.06; Plut.14.05; Plut.14.06; Plut.14.22; Plut.16.04; Plut.16.18; Plut.16.32; Plut.17.30; Plut.18.03-05; Plut.19.01; Plut.19.06; Plut.20.15; Plut.21.14; Plut.21.18; Plut.23.04; Plut.24.04; Plut.26.08; Plut 35.37; Plut.51.13; Plut.65.36; Plut.67.22; Plut.68.19; Plut.73.04; Plut.73.39
