----------------------------Original message---------------------------- I have seen several posts recently concerning the different acronyms and abbreviations out there as well as where they come from. Unfortuneately, I havn't always seen a way to access this information. ie an internet address, a snail mail address, a contact person, etc. Example: (Please excuse the following, I printed out a copy but did not keep a digital copy.) In a recent post, the original message was: Paragraph 4 of MIL-HDBK-850 : military handbook Glossary of Mapping Charting and Geodetic Terms (by the USA DOD ) , contains some relevant data. Where might one pick up a copy of this handbook? Thanks for your help! John
