Rubrics for the Old Mass

Some items that got my attention:

• In sung Masses the Epistle may be sung by a minister; otherwise, it suffices that it be read by the Celebrant, who however, may sing it in the usual manner. [link]
  
  
• If the Altar faces the people, the Celebrant does not turn his back to the Altar when saying Dominus vobiscum, Orate, fratres, Ite, missa est, or when giving the blessing, but having kissed the Altar in the middle, there extending and joining his hands, as above, facing the people, greets them and gives the blessing.[link]
