Good afternoon Folks: I have a case here that involves a pseudonym and may invoke the full implied force of RDA 6.27.1.7 but I should check before requesting cancellations. n 79123172 Law, John, $d 1854-1923 nb2007013259 Harkness, Margaret, $d 1854-1923 Magaret Harkness wrote under her own name and under the pen name John Law. It seems that ealier editions of thew work in hand, A city girl, simply had John Law as the responsible party, though the in-hand publication has John Law (Margaret Harkness), which seems to meet the inconstancy criteria of 6.27.1.7. It's difficult to say for certain, but one gets the impression that most everything she wrote as John law is now given the statement of responsibility John Law (Margaret Harkness). The Crichton qualification: the classic example of an author with multiple pen names is Michael Crichton, whose authority record has a very interesting 667: "Michael Crichton wrote 8 novels and 2 short stories under the name John Lange; these have been reissued with the statement "Michael Crichton writing as John Lange"; per RDA 6.27.1.7 the authorized access point for these works is Michael Crichton. The alternate identity authority record for John Lange has been deleted--LC-PSD, August 14, 2014." As is, 6.27.1.7 states unequivocally that any works with responsibility split between one author's true name and pen name should be entered under the true name: not Law, John, [dates]. $t City girl ..., rather Harkness, Margaret, [dates]. $t City girl ... .The Crichton qualification takes this to its logical conclusion, but isn't stated explicitly in RDA so far as I can tell. My question to you all: a record for Harkness and Law, or one record where Law is a cross reference to Harkness?
