One notable feature of the edition is that it includes material which the obituary of Warburton in The Musical Times described as "drawn in Warburton's own elegant calligraphy." Rather than having scores set in musical type, much of the edition has been printed from scores transcribed by hand for the publication and then reproduced. It also includes some facsimiles of manuscript sources and librettos to vocal works by J.C. Bach.
Noted music scholar Richard Maunder (best known for his completion of Mozart's Requiem) also contributed to the edition.
