The Chrysander edition of George Frideric Handel’s complete works is available online from the Münchener Digitalisierungszentrum (the Munich Digitisation Centre) of the Digital Library Department of the Bavarian State Library. The Library has a nice English language interface, but searching is a little odd. And it helps to know some German. The digital collection “comprises manuscripts, early prints, modern books, maps and photographic collections as well as journals and newspapers.” The access is free, but the images are not downloadable or printable. Still, it’s one-stop-viewing if you’re looking for a picture of Jimi Hendrix AND images of every book published in German-speaking areas in the 16th century.
