Note of interest: I have previously advised users "SXT" scribed in runouts denotes metal process at Santa Maria and Terre Haute press. Unfortunately, they have taken the advise of another user whom claims by "Fonts" in the label print indicate the opposite...CSM press from CTH process. See Queen - A Night At The Opera, and this label with "y" indicating CTH press and SXT in runouts, and also this release the same. Where labels were printed cannot possibly determine definitively where a disc was pressed. It only determines where the labels were printed.

Note: No more database manager according to staff member, but manager has indeed been making 'drive-by' rulings as of late.

Note on pressing in FTF
* And Use of Press or Pressing in FTF. We don't know from where it was decreed a suffix must be used.

The Mastered By/At; Lacquer Cut By/At credit roles have been misconstrued 3 ways to Sunday concerning what is general and what is confirmed.
*** the bottom line

Just another rebellious obsession of how I enter BAOI descriptions

Management's latest stand on BAOI description (caps)

The ruling from management is we don't disturb existing baoi, but enter any variants separately, and in their entirety (matrix, SID codes, etc.). Do not combine (variants 1 & 2)
