4. Readings
Lectio Divina Notes blog - Provides Sunday Matins readings and guide to weekly readings in the Office, as well as notes on selected books of the Bible.
Liturgical Readings
Divinum Officium website - The pre-Tridentine monastic option does not actually follow any known Benedictine calendar, and the readings and responsories are arranged as for and taken from the Roman Office, but still a useful source for translations of the texts.
Liber Hymnarius website - fantastic resource of online sound files, nicely arranged so you can find the appropriate seasonal tone
