We just launched a new image permalinks feature for downloading and linking to page images of books hosted on the Internet Archive. Using a page image permalink makes it easier to references the contents of a book hosted on the Archive without having to know the details of how or where the book is stored. Since a book’s data could be moved around within the multiple petabytes of data in the Archive at any time the permalinks provide a consistent and stable way to access the page images.
Here are a few quick examples. For each of these URLs you would add http://www.archive.org/download/{item identifier} to the beginning (hover over an image to see its full URL).
Referencing the cover image for a book at thumbnail size:
