    Thanks Herbert
    
    I am more inclined towards the systematic, geometrical / analytical
    approach. I am mainly interested in visual representations of how the
    projection is created (cone, cylinder etc. and where he 'light' is coming
    from) and what the resulting graticule looks like. Also, hw suitabe it is
    for various types f navigation and what would be the appearence of great
    circles, small circles and Rhumb lines.
    
    I find books with sharp, coloured graphics and clear layout much easier to
    read. Some very good text books on vatious subjects are let down by poor or
    non-existent graphics and by indifferent layout.
    
    In the meanwhile I found what appears to be a good treatment of the subjects
    in the following website of Mr. Furuti.
