Industry Ratios Missing

Editions of D&B’s Industry Norms & Key Business Ratios; RMA’s Annual Statement Studies; and Troy’s Almanac of Business & Financial Ratios, went missing shortly after the reference books were put on the reference shelves.   Searches have been/are being made.   Consequently, the most recent edition we could find of each title was put on Reserve this past Saturday.  I notified the professor and he has notified his students.   The OPAC records show which edition(s) are on reserve, but may also show other editions as being on the Reference shelves even though this  is not currently the case.   I’m looking into having the OPAC records reflect the missing editions.
