Subject:      enumeration ser lev 4

Older volumes of Journal of Psychology were published as:

  "volume 62, First half January, 1966"

They also published 3 volumes per year.  We have:
 volume 62, first half    Jan. 19966
 volume 62, second half   Mar. 1966
 volume 63, first half    May 1966
 volume 63, second half   July 1966

Our policy is to compress as much as possible.  If volume is complete
we eliminate subordinate data.  In this instance, holdings would
read as:

  v.62(1966)-v.63(1966)

Since this might be confusing, I am inclined to retain subordinate
data and still compress.  My question if how to note the subordinate
data.  Since publisher does not use "no." for caption, and per
ANSI Z39.44 - 1986 abbreviations are only those listed in AACR2,
my best guess is the following.

  v.62:1st half(1966:Jan.)-v.63:2nd half(1966:July)

Would this be correct, or have other libraries taken liberties with
the enumeration and treated "first half" as equivalent to "no.1"?

Thanks for your assistance.
