Hi there,
I normally work with rare books, but I occasionally catalog cartographic
materials as well.
I don't do them regularly, so it's like I have to relearn it every time
I start again :/
I have 2 cadastral maps in hand. They show the same exact area (same
neat line dimensions), with the same title, pub, date etc. but they're
are distinct differences between the 2. one copy is on a larger sheet
(map would be on the inside (or backside?) of a large originally folded
pamphlet). this copy also has a lot of text (on the "cover" side about
the construction company and the area being developed). The 2nd copy is
on a sheet a tiny bit larger than the neat line dimensions, looks
exactly the same, except there is no additional text. I don't know if
there's any text on the backside as it has been mounted on thicker
paper. Looks like it was folded too, but to much smaller dimensions, and
I don't know if it was issued that way. Also, the 2nd copy has been
updated to show more lots were sold (sold lots are highlighted in red),
so it was obviously issued later than than the 1st.

So question #1, does the second map get a new record or is it added as a
2nd copy w/differences detailed in local notes?

Question #2, do sheet maps get work letters attached to dates when more
than one version of the same maps is issued in (presumably) the same
year (like books do)?

Question #3, even though they were originally issued folded, they are
currently unfolded and encapsulated. So, if my understanding is correct,
you physically describe them in their present state in 300c. Should I
make a note describing original folded state and dimensions?

Thanks,
-Silvana
