Thanks to the hard work of Aristotle Esguerra, we now have a spreadsheet that contains translations of all the Gradual's propers for weekdays, as well as information on the propers of saints (contains mode and incipit, no translation yet). It is specifically designed to be used in conjunction with SEP, but undoubtedly, it has many other uses as well.

Also, in the last two columns are the source files for my website on the Ferial English Propers. With a few small exceptions, they were composed by me (or copied from SEP, depending on the situation). You can find the GABC for any proper found on that page (note that my page is computer generated, so anything found on this spreadsheet automatically propagates to my page).

If you ever need to plan daily Masses with music, this is an amazing resource, even just as a reference so you don't have to poke through the GR if you're looking for something.

I hope this is a great help for all those here.
