--- Comment #25 from Janusz Kaczmarek <januszop at gmail.com> ---
Here some more details, what and why goes wrong:

100 1  $a Shakespeare, William

-- It does not make sense to include in the query (and check)
subject-heading-thesaurus, since we are looking for auth for 100, not for 6XX
(It would have sense to check 008/14 of the auth. rec., but this is another
story)

655  4 $a Literatura światowa

--For ind2 == 4 we should look for an auth with 008/11 == ‘|’.  In the proposal
the search is being performed for subject-heading-thesaurus = 'n', which is
wrong (008/11 = n is used in auth when "1XX heading does not conform to subject
heading system/thesaurus conventions and is not appropriate for use as a
subject added entry in bibliographic records" -- that is non intended for use
in 6XX, would have 008/15 = 'b')

655  7 $a Literatura angielska $2 DBN

-- It is correct to look for auth subject-heading-thesaurus = 'DBN', but in
case of failure the second search should be performed with
subject-heading-thesaurus = 'z'.  This is because 040 $f is not obligatory for
008/11 = 'z' (according to MARC 21: "A MARC code for the conventions used to
formulate the heading MAY be contained in subfield $f (Subject
heading/thesaurus conventions) in field 040 (Cataloging Source)".  If there is
only one thesaurus present in the system, it is legal not to have 040 $f in the
auth recs., having $2 in 6XX in biblio.

700 12 $a Shakespeare, William. $t Othello

-- Same as for 100 -- no sense of querying for subject-heading-thesaurus.

830  0 $a Great Books for Busy People

-- Same as for 100 -- no sense of querying for subject-heading-thesaurus.


I have not enough courage to remove the status 'Passed QA' but IMHO the patch
should be reviewed again.  Otherwise we would have to patch the patch right
after its application.
