----------------------------Original message---------------------------- GPO's Superceded List tells what a depository library may withdraw and it also indicates what regionals have decided to keep in spite of the maps being superc eded. It doesn't indicate that regionals are to keep superceded DMA nautical c harts and the NOS charts aren't even mentioned, until the first edition of the Administrative Notes Technical Supplement. It doesn't indicate in there that t he NOS superceded charts are to be kept by the regionals but nothing in that su pplement is marked "regional". There are series in the Superceded List that are to be kept by regionals, such as the CIA maps, Forest Service maps, etc. Are we regionals keeping the ones they say we are? Who decided this, when?
