Here are f messages concerning the old chart question.------Johnnie ------------------------------------------------- Mon, 05 Apr 93 15:27:44 EST David Cobb <DCOBB@HARVARDA> Re: Old Charts We have several of these (several!) and use the 1890 Catalogue of Charts and Other Publications produced by the U.S. Coast and Geodetic Survey. Despite their being out-of-date a of no value for navigation they are valuable historical documents in and of themselves. We are considering cataloging those indvidual charts for the local New England waters as I believe it would make them much more accessible and useful for our patrons and ourselves. David A.

The pamphlet with numbers translated from old to new that USC&GS put out at the time of the changeover is extremely helpful for doing this. Also, the general principle at UCSB is "Till your own garden;" so we keep old editions of CA-coast sheets, but heartlessly toss anything else in the USC&GS series. For foreign nautical charts, we've tended to keep old editions, filed at the appropriate charts number (probably because we have far fewer of these). We've tended to keep old editions of DMA/HO charts, not knowing who's keeping them; but (if I'm remembering correctly), we don't necessarily keep all editions, perhaps one every ten years.

The publication is arranged by chart series. It's N.O.Pub. No. 1-N-L. It's 68 oversized pages and I only have 1 copy in my library or else I would offer you an extra copy. It has two listings: New N.O. chart numbers to old chart numbers and old chart numbers to new. I checked on your example and old #5984 is listed as new #18185. If this is the same map, then maybe the new # was correct in 1971 and has since changed. Does anyone have more info about this discrepancy. The librarian who was in charge of the map collection before I got here renumbered the charts so that they were all in one numerical arrangement. I haven't really used this listing very much.
