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.

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. :)

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.

So far it works, I am currently downloading a PHP 5 book to learn PHP5! Goo userscripts and google!

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)

You should add the link to download manager extension.

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.

As the title says, I installed this and went to books.google.co.uk and found the book I was interested in. There were two different ones I wanted - one was available as 'full preview' (meaning google already allows it to be downloaded!) and the other was only part preview( no download link given so the script would be really handy!)
I tried the script with both and although the download link appears OK on the left side of the page, when I click it then it asks which page to download from...but the drop down box to select the page numbers was empty and never had any numbers in it.
therefore no pages were ever able to be downloaded.
Is it fixable or have google gone and stopped this being possible..?

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.
