When there is volume and number, but no month, but the
          year is regular, our library has traditionally kept the year
          in the numeric/chronological designation area (362 field)
          and used the date in the call number on the bound volumes.

          I haven't seen problems arise from this, only that the vol.
          and year correlation/regularity might change.  However, that
          doesn't impair identification; this practice is pretty
          harmless.  It probably much more useful for users to see how
          old the volume is.
