PPV （Pay Per View） is a kind of single paper supply service provided by the publishers, which is developing quickly in the west countries. Almost all the large publishers, except the open-access journal publishers, supply PPV service via their own platform or via the third party. With the PPV service management is being improved, more and more libraries take PPV as a sus- tainable method for documentary guarantee.
