I found some bookmarks that I had saved a long while back. Although they don't work any more, I could build working ones by trial and error that give you "online" views of arbitrary books.
For example:
http://www.gutenberg.org/catalog/wor...5812&pageno=20
A General History and Collection of Voyages and Travels — Volume 02 by Kerr
(bookmark to page 20 of this book)
