Will it be available as a pdf as the first edition was? I find that useful for creating a packet of Propers+Ordinary+other music and chant in my desktop publishing software, even though all my singers have the actual book.

yep. I'll see about getting that up tomorrow

See musicasacra.com/pbc as the main landing page

Thank you so so much for this, it is marvellous.

Received my copy yesterday, reviewed it briefly, but I did chanted the Dies Irae last night before bed, I like the way it is divided into section, which show the repetition of chant melody to make a long piece like this less intimating for the beginner. I think the additional of the Requiem Mass is great because in my limited experience with the Chant in the actual parish setting, other than Mass Ordinaries this is most likely the propers you might hear as or be asked to offer as a schola. This addition will make the PBC a more comprehensive resource. Thanks to all who worked on this excellent resource.
