I have trouble understanding the instructions published in the Guide. Specifically:
For August 22, Queenship of Mary 
From Com of BVM 1628.
OOR 1152, Rd 131 & 1338, pr 1341
Ps 1134, Pr 1338, Etc.
OK. I start on Page 1628 with the Invitatory and the OOR and the First Reading from the Prophet of Isaiah, then move to 1338 to for the second reading.
Here is my confusion: Since I have already prayed the OOR form the Com of BVM on pgs. 1628, why do the instruction in the Guide also list the "OOR 1152". This appears to me a duplication of the OOR for that day. Should both the OORs from 1628 and 1152 be read or can a person choose which one to read. Thank you for our help.
We pray only one OOR (we won't consider the anticipation on the night before kind of thing) so there's no need to duplicate at all.
First principle we must understand: the Queenship of Mary is a Memorial, therefore, the rubrics governing memorials apply.
For the Office of Readings, OOR 1152 means, you recite the Psalms and Antiphons for Wednesday, Week IV.
The first Reading is from Isaiah (Rd 131) and the second one from the Memorial (Rd 1338) as you correctly did.
In this case, there was only one other item for the OOR you could have taken from the Common, and that is the Hymn. Because it was a Memorial, you recite the Psalms and antiphons from the weekday, not the Common.
