Here are additional comments about how these works were produced:

• Hymnarium O.P.:
  • In the case of the Hymnarium, it was produced almost entirely with Gregorio and LaTeX — the only InDesign work involved was the cover. [Producing] such a large book with LaTeX as the main basis [. . .] saved a lot of time with the automation of the indexes, the cross references, and so forth. (source: Innocent Smith, O.P.)
• Lumen Christi Missal, Simple English Propers, Ad Completorium:
  • Steven Van Roode [. . .] uses Gregorio only for the notes, then tweaks the result with Illustrator and does the final typesetting with InDesign. (source: Olivier Berten)
• Parish Book of Psalms:
  • Each psalm setting was engraved using Gregorio and LaTeX. A LaTeX template was used to provide a consistent appearance for the engravings, and Perl programs were used to automate the batch processing of GABC files into PDF files. Individual PDF files were assembled into the book using InDesign. Other pages (title, contents, indexes) were added in InDesign. (source: Richard Chonak)
