Not sure I completely agree. For historical maps--modern maps that show
historical events or processes--many libraries (including this one) tend
to use S thematic codes plus publication date in the call number. The
date of situation is implied by what comes after the S. A modern map
showing particular conditions in the Middle Ages might then have a call
number like G5701.S2 [pub. date] .[main entry Cutter].

I don't believe LC has ever quite decided which S codes you should use
between S12 and S65, so it _is_ hard to be consistent here. And I
acknowledge that the distinction between a map of a place at a
particular point in time and one that focuses on historical events or
processes is not always clear ...

Bojana,


DEFINITELY use date of situation in the call number in all instances.
That said, in "real life" most often one is left with the date of
publication or a copyright date to go from, so as you look at lots of
copy over time you will see the date in the 260$c (in AACR2) or 264$c
(in RDA) being the one also used in the call number.


The date in the call number should if at all possible reflect the date
of cartographic information shown on the main map(s). There are two
exceptions to having a date in the call number at all to also be aware
of, for map sets/series we use a shorthand way of expressing the scale
of the main map(s), or when you have to use "Scales differ" or the
much-more-rare "Scale varies" in the 255$a then we put "svar" in the
call number instead of a date.


In your particular instance you want to reflect the time-period
involved/shown on the map, the "Middle Ages", because that is the age of
the information shown. (and please don't use a range of dates like
1100-1600 in your call number) Here's the best places to look at
specifics related to date of situation:


LC's Map Cataloging Manual: see page 1.16 (and at the top of that page
see the nice table "Filing Order for Map Classification Numbers" so you
can visually see what I'm talking about with things like "svar" or "s25"
and similar) through 1.19. SPECIFICALLY see the following LC practice at
the bottom of page 1.17:

"When the date in the call number is based on a range of dates for
information depicted, the later date is used in the call number." --
this addresses your particular situation and so you would use the ending
date for the Middle Ages in the call number.


Appendix C of /Cartographic Materials: A Manual of Interpretation for
AACR2 (/and information about publication dates in rules 4F1-4F11 also
can provide some guidance by seeing what to do in the 260 or 264 dates
subfield)

And, since what you use for date in the call number in this instance
(1600) is going to be misleading, it would be a good idea to construct a
500 note indicating to the reader that this map shows activity across a
broad range of time, unless that is very clear in the title itself.

Feel free to work with me further on this area...

Paige

Hi All,
I have a map cataloging question about which date to record in the LC
call number: the date of situation or the date of publication? I know
that usually we use the date of situation, but this example is tricky
because there is no date listed on the item (ocm31265380). A
cataloger-supplied date I found in the bib record says “1965.” However,
this is a map of trade routes and commerce in Europe in the “Middle
Ages.” (There is no EXACT date, but I’m guessing 1100-1600?) For a call
number I have G5701.Q1 1965 |b T4. In this case should I just use that
inferred-publication date, or should I use 1100-1600 in the call number?
Any suggestions welcome J
Thanks!
