This site contains many dysfunctional links and requires the use of Adobe DRM software that is a privacy risk and as such, is not a viable alternative for documents of any kind.

ottimo sito per trovare libri gratuiti, soprattutto in lingua inglese. Molto materiale tecnico e scientifico. Interessante anche per una ricerca storica di vecchie pubblicazioni, anche del 1800 e talvolta anche più antiche.

Greate site. Watch out if it's readable in the corner up right. When it's not, there just appears a new window with a strange site you need a password for.
