I agree that this title _could_ have a uniform title. By historical practice, it does not _need_ one. Liver is the only title that this work has been published under. If a first edition with no creator were catalogued today, it probably would get a uniform title. But the work has gone without a uniform title for 38 years.
If this record is given a uniform title, then all previous editions should also get the same uniform title. This would require a BFM to the Library of Congress for five previous editions. It is an awful lot of work to fix something that is perfectly acceptable by historical practice. As I suggested above, I expect that the Library of Congress will remove the 130 when the edition is fully catalogued.
Since the title proper is just Liver, it probably does need a 130.
2 quick questions about a work-level AAP used in this bib record (lccn 2019024961).
130 0 Liver (Arias)
1) The qualifier “Arias” sounds a bit funny and “untoward”, so to speak, since it happens to be a variant form of the lcgft term “Songs.” We all know, for machine indexing and data manipulation, it does not matter at all. But for a human to read and comprehend what it is, would it be better to see a more understandable heading like “Liver (Reference work : Arias)”?
2) This is the 6th edition of the work. At this point, would an expression level access point be more appropriate?
130 0 Live (Arias) $s (6th edition)
Per OCLC bib file, the first edition was published in 1983; Irwin M. Arias has been its chief editor since the 1st edition. I am not questioning the use of work-level AAP in this bib, seeing that it stands for “[a] distinct intellectual … creation.” I am just inquiring if there’s a best practice when we come to deal with reference books/textbooks that have gone through multiple editions.
If a work-level AAP is all we need, so be it. But if an expression-level AAP is more uniquely helpful to library users, then, why not?
