Am I correct in stating that while the parentheticals can appear in a bib record, LC has not lifted its moratorium on using parentheticals in authority records to distinguish between the work as music and as libretto when the composer and librettist are the same person?  This is the extant AACR2-coded authority record for In the Heights:


010  no2012092061

040  OhKeUHG ǂb eng ǂc OhKeUHG

1001 Miranda, Lin-Manuel, ǂd 1980- ǂt In the Heights

670  Miranda, L. In the Heights [SR] p2008: ǂb label (In the Heights : original Broadway cast recording) container (music and lyrics by Lin-Manuel Miranda; book by Quiara Alegría Hudes)


Under RDA, there should be two ARs for the individual works:


1001 Miranda, Lin-Manuel, ǂd 1980- ǂt In the Heights (Musical)

1001 Miranda, Lin-Manuel, ǂd 1980- ǂt In the Heights (Libretto)


LC’s Music Bibliographic Access Section placed a moratorium on creating separate ARs in May 2013 and participants in the NACO Music Project informally agreed to follow MBAS.  Has LC changed its mind about this in the last 16 months?

Thanks for catching this, Mark.  You're correct that the parenthetical qualifiers for (Libretto) and (Musical) in this example in the MLA Best Practices should be switched.  In fact, the OCLC record appears to have been edited to correct this:


1001 Miranda, Lin-Manuel, ǂd 1980- ǂe lyricist.

24010In the Heights (Libretto)


7001 Hudes, Quiara Alegría, ǂe librettist.

7001 ǂi Libretto for (work): ǂa Miranda, Lin-Manuel, ǂd 1980- ǂt In the Heights (Musical)


I'll make a note of this so that the example in the Best Practices can be corrected.

The first time I looked at this example, I saw that the person in field 100 is the composer.  But no subfield e composer is present.  I wondered whether a second field with the same heading, with |e composer, would be present (it would have to be tagged 700).


Since this is a text-only work/expression, the composer role would apply to the related musical work.  That (ideally) is covered by the record for the musical.  But bib records can be a tangle of relationships sometimes two or three steps removed from the item being described...


There's a 700 field for that heading with subfield i containing the relator term Libretto for (work).  But I don't understand that field, because the term libretto is also in parentheses following the title in subfield t.  (A libretto for a libretto? That's how it reads to me.)


Yes, this looks like an error to me too--the parenthetical qualifiers in the 240 and that 700 should be flipped around at the very least.

I'll leave the question of librettist vs. lyricist as main entry to someone else.  Though in the 245 $c of that sample record, I do note a "conceived by" credit for the composer-lyricist.
