The PDF Orders of Service for Mass below have two columns per page and are formatted for print, already imposed as 2-up. They are not suitable for reading on mobile devices, but are intended for printing.
Said Mass (PDF)
Sung Mass (PDF) (Your browser may not be able to display this as a two-page spread. Right-click and download it instead.)
Also intended for printing or viewing on larger devices are the St Michael Antiphons by Richard Rice, which we are currently using at the start of Mass. Previously published on Lulu, Dr Rice has recently made much of his work freely available.
