Dear collective wisdom,
I was wondering on best practices for creating authority records for pseudonyms beyond what is covered on the LC/PCC FAQs on individuals with more than one identity.
If an individual only uses a pseudonym, we're instructed in RDA 18.104.22.168 (exception), RDA 22.214.171.124 and the aforementioned FAQs to input the person's real name, if known, as a 400. This seems a bit unethical to me. If this person does not want their real name associated with their works (hence the use of pseudonym), why are we making this explicit? In many cases with pseudonyms, a person has their real identity outed without their consent, and I question our complicity in this by publicly sharing this information in the NAF (see, for instance, the outing of J.K. Rowling as the real identity behind Robert Galbraith )
I also question using biographical information for the real identity when describing a pseudonym. Author's might decide that their pseudonym has a different gender, nationality, birth date, etc. then themselves for a myriad of reasons (like the endless list of women writers that decide to use male pseudonyms because, as Charlotte Bronte puts it, "we had a vague impression that authoresses are liable to be looked on with prejudice" ). Records like no2018033569 (Cunha, Eduardo, ǂd 1975-), n 79045512 (Eliot, George, ǂd 1819-1880), n 78081235 (Sand, George, ǂd 1804-1876) - just to name a few off the top of my head - all carry biographical information of the real identity, which does not describe the pseudonym.
It seems to me that the same best practices suggested for recording information about gender  should be applied for pseudonyms: "Do not dig for given names or genders assigned at birth". Which is to say, describe the identity associated with the pseudonym, and do not dig for information regarding the real identity.
I'd love to hear your thoughts and practices on the matter.
