Thanks. My personal copy is 1999. I looked for the document on an UK Ordnance Survey website, but I couldn't find it + the tea was ready. Page 6 is still the relevent page. DaveP
If you enjoyed the Greenwich Meridian link I posted, you will love this one A Guide to Coordinate Systems in Great Britain (pdf). I don't claim to understand more than about a third of it, but it looks very impressive lying around the office. It's a bit long, so if you just want to see an example of the same lat & long corresponding to three different spots depending upon the datum used, just turn to page 6. DaveP
[NOTE from FER: the original post referenced a slightly out-of-date copy of this document in an obscure blog. The current link is from the British Ordnance Survey's own website and appears to be the latest edition of the document].
