More suggestions to solve the problem on peculiarities in numbering of
"Popular photography" from HKUST serials catalogers and myself:

1. Add 515 note
     Issues for May 1993-    called also v. 57, no. 1-    , but constitute

     v. 100, no. 5-     .

2. Close volume numbering in 362 field
    Vol. 1, no. 1 (19  )-v. 100, no. 4 (Apr. 1993); May 1993-
    ( I haven't searched its OCLC record for the beginning date)

3. Switch to mark May 1993 onward by year

4. Leave the publisher alone
