"The string quartet, for two violins, viola and violoncello, was one of the most widely-cultivated genres of chamber music during the Classical period, with the Viennese masters Haydn, Mozart and Beethoven all contributing substantially to the literature. The David M. Rubenstein Rare Book & Manuscript Library at Duke University has about forty collections of string quartets in parts dating from this time (about 1770-1840), most, though not all complete, and representing composers whose works are rarely found in modern editions. Digitization of these parts makes newly available for performance, study and recording a large and varied repertoire of works for this instrumental ensemble."
"From incunabula to manuscripts, from books of local customs and manners to Valencian literary classics, from historical monographs to regional law treatises, the digitalization of all these works and their inclusion in BIVALDI allows free and optimum access to readers from all over the world. BIVALDI also has transcriptions, translations, bibliographies, special studies on the digitalized works and their printers, author biographies, etc."
