More Munich Manuscripts
Now I found that the library has digitized many more manuscripts, including quite a few Hebrew ones. Especially noteworthy are Ms. Heb. 140-141, containing tractates from Seder Moed and part of Yevamot, and Ms. Heb. 6, with Pesahim, Yoma and Hagiga. They are both important, early examples of the Spanish textual tradition. Another major representative of this type is the Hamburg manuscript of Masekhet Nezikin, completed in Gerona in 1184. Shamma Friedman has explained why we need to be careful in using them, because their text underwent scholarly glossing. But they are definitely important, and these characteristics just make them more interesting.
There's also a fragment of Siddur Rashi that I will have to check out one of these days.
