The Open Book page image presentation framework is not designed to replace printed books, nor emulate HTML. 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 worldwide.
For most effective printing, use the "print" button available
on each OpenBook page's tool block. The 300 x 150 dpi PDF
linked to it is printable on your local printer.
