Record 93-047518 (OCLC# 29595260), Advances in genetic programming (MIT Press, 1994-1999), has its encoding level set to "J" (deleted record).  And yet it is the only pcc-level monograph record for this work.  There is another DLC-created record (#472723186) which has encl: M.  Does anyone have a clue why this record was marked as deleted?
