Ken, you wrote: "You are partly right about the copyright issue. Even though, as you say, no one owns the position of Mars, the British claim copyright to whatever data they collect." That's ok, but they are not responsible for collecting more than a trivial amount of data underlying the present Nautical Almanac, and there is long-standing precedent for relinquishing copyright to that portion of the data that the UK did collect. The whole content of the Nautical Almanac can be re-generated from scratch in no time. And: "They even extended this thinking recently to tidal data in British ports. Since they collected the data, they have stopped several tidal prediction programs from being sold without paying a royalty for the British part." Yes, and that ruling also applies to international ports where the data has been collected by British authorities. In this case, they have a point. I certainly wish they would make it available for free, but of course, collecting this tidal data was expensive and it is primarily relevant to commercial users. This is a product, and there's no strong reason to give it up for free. And: "A case over international copyright of data might go either way." But not ephemeris data. No way. There is no rational court in the world that would award copyright over the positions of the stars and planets to any authority in the UK. Indeed, the very fact that this information is presently available, and has been available for decades, in numerous products and in numerous online databases *without* contest by any authority claiming copyright guarantees that there is no legal case for copyright of the data in the Nautical Almanac. And: "However, the British also claim copyright over the page layout of the almanac which is a creative issue. Most everyone agrees that that claim is proper." It is a proper "claim", yes. Even that could be argued over since most of the layout was published in the American Nautical Almanac *before* it was adopted for the common Nautical Almanac. This is the sort of thing that could go either way in court. But we don't have to argue it in court since the layout's not terrificly important in any case. The specific layout of the Nautical Almanac is hardly sacrosanct, and it would be easy to devise layouts that are functionally equivalent or even considerably superior. There are many navigation enthusiasts, for example, who might be happier if the daily pages were not cluttered with tables of twilight, sunrise/set, and moonrise/set (wouldn't that be a nice spot for some lunar distance tables...). Of course, for some navigators, even the tiniest change in the Sacred Almanac Layout adopted in 1958 would be an abomination against the Ephemeral Gods themselves and there might be rioting the streets! But I think not. -FER 42.0N 87.7W, or 41.4N 72.1W. www.HistoricalAtlas.com/lunars
