    Re: What's on your bookshelf?

    I do not think that Cugle's is worth the effort of a search for you. I
    have had a copy on my bookshelf for over 60 years and have not cracked
    the cover more that ten times, and then only in search of some oddity. It
    is primarily a compellation of computational rules intended originally as
    a study guide for US Steamboat Inspector's examinations, as well as the
    necessary regulations associated with those examinations, now long
    outdated. It was quite popular in the US during WW II in the training of
    Merchant Marine offices who had little or no mathematical background.  If
    I remember correctly, I purchased it in 1942 because of a need for quick
    access to the fuel consumption formulae contained therein. The format
    does not apply to reason but rather to memorization of methodology. Of
    course, it you just have to have it as an historical oddity, by all means
    go for it.
