The Open Book page image presentation framework is not designed to
replace printed books. Rather, it is a free, browsable, nonproprietary,
fully and deeply searchable version of the publication which we can
inexpensively and quickly produce to make the material available
For most effective printing, use the "printable PDF page" link available
on each OpenBook page's tool block. The 300 x 150 dpi PDF
linked to it is printable on your local printer.
