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...

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!
