[ilugd] PDF files restriction on google-books site (cannot save or print them)

Hello, The google-books site shows various books, supposedly in pdf format. But, these files, can only be viewed. They cannot be saved or printed. Any idea on how is this achieved ? Thanks. Sudhir Gandotra www.openlx.com ___ Ilugd mailing list

But, these files, can only be viewed. They cannot be saved or printed. Any idea on how is this achieved ? no idea how it was/is achieved , but something similar can be done using http://flexpaper.devaldi.com/ and many other similar projects , did not understand why you want to restrict it ?
