    This is worth emphasizing. When you read them online, you have
    indirect access to OCR text conversions which can be fully searched.
    For example, if you go to google books and type 'latitude "double
    altitudes" date:0-1900' [keep the double quotes, drop the single
    quotes] and then search, google books will happily dig through every
    book in the collection and find all books through the 19th century
    containing the word 'latitude' and the phrase 'double altitudes'
    anywhere in the book. You get over 300 hits and more than 50% are
    directly relevant for those of us interested in the old navigational
    methods ...a year's worth of reading from ten seconds of searching.
    This particular search returned every navigational manual and
    commentary that I have ever found on google books previously. I
    suppose it's just broad enough and just unique enough, too.
    Among the books you will find via this search (by author, as they're
    commonly given): Chauvenet, Sumner, Bowditch, Taylor, Merrifield,
    Peirce, Maury, Inman, Simms, Kerigan, Blunt ("American Coast Pilot").
    And Moore!
