In 2015 Bärenreiter issued Requiem KV 626: Faksimile der autographen Partitur in der Österreichischen Nationalbibliothek, a complete autograph edition of Mozart’s Requiem.
The surviving manuscript reflects its dramatic history: Mozart’s handwriting and the supplementary entries by Süßmayr and others often appear on the same page. The corner of a page where Mozart wrote down one of his last musical ideas was later stolen; it is still visible in an old photograph. Each page is individually cut to match the manuscript, conveying a vivid impression of the original. A foreword discussing the genesis of the Requiem and a detailed description of the manuscript complement the facsimile score.
Below, an excerpt from the work.
Digital Image Archive of Medieval Music inaugurated the series DIAMM facsimiles in 2010 with The Eton choirbook. Edited by Magnus Williamson, the book presents a full-color facsimile edition of Eton College Library MS 178, an iconic source of English choral polyphony composed during the late fifteenth and early sixteenth centuries that has been continuously in the possession of Eton College since it was first copied for use in the college chapel in the early 1500s.
Facsimile editions may present reproductions of illuminated manuscripts; they also may document creative processes, like the famously scrawled and blotted manuscripts of Beethoven.
In rare cases facsimile editions provide evidence of collaborative processes; an example is the recent edition by Leo S. Olschki Editore of the working copy of the libretto for Puccini’s Tosca, part of which is pictured above.
With notes in the hands of Puccini, the publisher Giulio Ricordi, and the librettists Luigi Illica and Giuseppe Giacosa—and the inclusion of pasted-in pages fathfully reproduced as separate, attatched sheets—the edition documents the collaborative process that resulted in one of the landmarks of verismo opera.
