My apologies if this has already been asked and answered ... I wasn't able to find to anything about it in the list archives. The instruction in RDA for recording longitude and latitude at 7.4.2.3 says "Separate the west and east coordinates with a hyphen and the north and south coordinates with a hyphen. Do not use a space before or after the hyphen." But I've yet to see anyone do that! In all the RDA records I've seen that have coordinates in a 255, they are always separated by two hyphens as in AACR2 (which called for a dash instead of a hyphen (3.3D1)). I just now looked a random sample in OCLC of about 100 LC RDA records for CMs published in 2014 or 2015, and every single one of them that had coordinates in a 255 $c used two hyphens to separate the east and west and the north and south. That of course looks very natural and correct to me, but I can't find an LCPCC PS or any statement elsewhere in RDA overruling the instruction in 7.4.2.3 to use one hyphen. In Mary's and Paige's and Susan's excellent /RDA and cartographic resources/, they state the RDA instruction from 7.4.2.3 verbatim (in quotes), but all of their examples show two hyphens. I would appreciate it if anyone could shed some light on this! Aloha, Mike Michael A.
