It can also be optimized if merged with some more programming and the the code merge all the images and output a pdf file instead. :)
But too much from GM script I think. Will see if It can be done with PHP. :)

Hi Redphx,

I would like to thank you for this script, because in my country books are very very expensive.
Congratulations for your script, but Google Book changed and this script don’t work as before (don’t find the pages).
I think that we need to wait for new version.

Dart

This script provides you with links to all the pages of the book. In that sense it works well. What's confusing is what to do next. Many users seem to think that the books gets saved automatically, but they do not; another download manager has to be used (Flashgot or Downloadthemall) to copy all of the images from all of the links. However, this process is not easy to orchestrate and the resulting files aren't often arranged sequentially. Some documentation would be helpful though it can be found elsewhere on the web.

Useful tool. If this wasn't there, I'd have to take a screenshot every page and save it. So, I'm really thankful for this.

I've always found this script good, but I note there appears to be a version 2.3 modified by a different author here:
http://userscripts.org/scripts/show/110805
At a cursory glance it seems pretty similar, just with a few new tweaks

i would like to say to the admin for script for activate greasemonkey or books downloader, because i still enjoy till now for download some books with free. so i feel enjoy for reading and studying everything i want. so, thanks to you much.

This programs may have worked well once but it certainly hasn't performed well for awhile. It may be abandoned (no one seems to know) and it can be a bit difficult to understand for beginners. At this point it isn't worth using unless there's some update of features.

This is a time saver and works well with the current version of FF.

...especially about downloading all the pictures. It could make a list of URLs for Orbit Downloader, for example.

Version 2.1 appears to have trouble locating download links when a google preview loads at a page other than the first page.

For example the following link loads page #168, but the "Download this book" button does not appear:

http://books.google.com/books?id=3Gj0rLx9gy0C&p...

Same is true for the "Download this page" button (i.e., PA169) on the next page (i.e., page #169)
