I thought a classification number was a number or letter-number
combination constructed from a library classification system (LCC, Dewey,
or another) whereas a call number was a classification number plus a
Cutter number and possible edition marker such as a year plus or minus
other letter-number codes, or an accession number, used for locating an
item on a shelf in a library (this overlaps with but is not identical
with the distinction Lowell Ashley made).  In other words, in Dewey the
classification number is typically the first line of the call number, and
in LCC, the classification number is typically the first 1 or 2 lines of
the call number.  The term "line" refers to call number segments
printed on different lines in the stacked call number format typical of
spine labels.
