Google Books Search Types

Most search engines provide hits in order of 'popularity'; GOOGLE Books allows you to alter this, so that you can search. for example, 'architecture' as normal, but click in the left-hand options column to restrict the search to the most recent books publihsed, or books in the nineteenth century only; a pop-up calendar enables you to custom set the search for the exact dates you're interested in. You can see these options if you double click on the webshot in the last entry.
