    Subject: [NavList 2587] IoN Celestial navigation CD
    Recently I have received the IoN Celestial navigation CD. In message
    [NavList 2480] there is a list of the articles, and is different, (279
    papers, not 286). Have I received a wrong version?
    * From article 30 to 134, the PDF files are protected, and printing is not
    allowed. �Is this an error?
    * n� 64: Vol. 23, No. 2, Summer 1976, Direct Methods of Latitude and
    Longitude Determination by Mini-Computer, CROCKER WIGHT, is incompleted in
    page 150.
    * I have some printed papers from the IoN not included in the CD: Optimal
    estimation of a multi-star fix, DeWit Vol21n�4 1974. The method of coplanar
    vertices... Robin, Vol46n�4 1999, ...
    and he followed that with a copy of the contents list from the IoN disc,
    with 279 papers.
    George adds-
    I have checked what Andres said, on my own copy of this disc, and agree with
    his comments.
    The list of items that I quoted in Navlist 2480 was taken, not from the 
    contents list of the disc itself, but from the list quoted on the website of 
    the Navigation Foundation, at-
    That list gave those 286 numbered items, and is clearly inaccurate when
    compared with the disc itself. I can only presume that there was some slight
    slip, between the cup and the lip. The list of 279 papers, quoted by Andres
    in Navlist 2587, appears to correspond with the disc itself.
    The most serious aspect seems to be the inability to print a large swathe of
    the papers. As I understood it, the intention was that all would be
    I concur that something has gone wrong with the scanning of page 150. Also,
    Andres argues that two other papers should have been considered as having
    celestial content, and included.
    I am sure that David Burch, who made the selection for the Navigation
    Foundation and the IoN, would wish to know about the matters that Andres has
    raised. I know that he keeps an eye on the Navlist pages, so he is likely to
    be aware of Andres' posting, but I will copy this to him anyway, just in
