The New Liturgical Movement has an announcement up about a new chant book that the Catholic Music Association of America has put together. The key here is that it contains chant for both the Ordinary (Novus Ordo) and Extraordinary (traditional Latin mass) Forms.
Naturally, texts are in Latin but with English translations.
There is a section for seasonal hymns; sadly, office hymns are in short supply…
I thought for a second you meant the actual Romans.
