The piece  in  hand gives the Yiddish author's name  on  the t.p. verso in roman script, something like "Solomon Brodsky."
On the  t.p.,  he  calls  himself "Shelomoh Brodski (Shuler)."   The Leksikon fun der nayer Yidisher literatur  informs us that Brodski was  his original name  and Shuler his  later name.   Which  form should take precedence, the prominent roman  form  or  the later, i.e. the changed form?

CPSO replied that, since the later  form  is  on  the  t.p., that's the form that should be used  in  the heading, per 22.2C1.
So here we have  an example, not  only  of  a  form other than  a prominent  roman  one  taking precedence,  but  also  of  a  form presented in parentheses in  the chief source being used  in  the heading-- neither one a common occurrence.

This problem brings  back memories of  A.  Aviel Lipkunsky (nr95- 26920).   This author was "Avraham Avi'el" on  his
chief source (in Hebrew), and  "A. Avi'el Lipkunsky" in roman  on the  t.p.  verso.   On  p.  4  of  cover  he  was "Avraham Avi"el (Lipkunski)," in Hebrew.   CPSO  advised  that this case, too, seems to record a change of  name.   That  being  so,  the  chief source form  again takes precedence over  the prominent roman  form.

The literary author number PJ5054.G637 for Gur, Batya (nr 88006107) was established based on an earlier form of the
author's name (Goor, Batya).

It is not unusual to have the form of a literary author's name change for various reasons, or for a single author to publish under multiple pseudonyms.  LC policy, as described in the excerpts below from the Subject Cataloging Manual: Classification (F), is generally to classify the works under the number originally established for the author, and to provide a see reference in the classification schedule from the new form of the name.  Such a see reference appears from Gur, Batya to Goor, Batya in the PJ schedule.

It may seem problematic to have works appear "out-of-sequence" on the shelf or in a shelflist browse; however, it is simply not practicable to reestablish numbers and reclassify books with each occurrence of an author's name change.  As our online catalogs and other tools become more sophisticated, the cross referencing supplied in the name authorities and in the classification scheme should further minimize any difficulties encountered as a result of this practice.

The Subject Cataloging Manual, F632 on Literary Authors states:

Normally, all works by or about an individual literary author are classed together in the same number or span of numbers in Class P regardless of the number of names under which the person may be entered and regardless of any changes in the form of heading for the person.

The manual provides further clarification in the sections below:

1c.  Name changes for authors with established numbers.
If the name of an author with an existing literary author number changes significantly due to changes in cataloging rules, marital
status, etc., continue to use the existing literary author number, if any, derived from the earlier form of the name.  Submit a proposal to have the number printed in the appropriate P schedule, together with a see reference from the new form of name.

1d. Authors entered under more than one name.
Class works by or about an author who writes under several pseudonyms in the single number that has been established for that author, regardless of the name under which the work being cataloged has been entered.  Submit a proposal to have the number printed in the appropriate P schedule together with see references from all pseudonyms.
