At https://musicasacra.com/resource-lists/ the "Antiphonale Romanum (1960)" book is the standard resource for all day hours around the year, Benedicamus tones are back in the Toni communes section.

If you have physical copies of Liber usualis (copies of the Antiphonale are less common), the Benedicamus tones are also included there (look in the section with ordinary chants of the office), but only the Sunday and festal ones.

Thanks so much!
