The current state of Bitstamps order book is available here: https://www.bitstamp.net/api/order_book/
I want to analyze the history of the order book.
Do someone know if its available?

Bitcoincharts.com has the "market depth" for Bitstamp, which is just what you are asking for. It is presented both as a graph and a table with actual bid and ask volumes. There is a free API for much of their data, but (added in edit) to my surprise, the orderbook data does not seem available that way. If it will help you will depend on your application: There is a 15 minute delay.
There are many other sites presenting visualizations of the orderbooks of exchanges; one example is Bitcoinity.org's Bitstamp page. But I am not aware of any other than Bitcoincharts.com that provides a public API.
The question has been changed from asking if this data is available "at a third party" to whether it is available at all. Yes, it is available, from the first party (Bitstamp), via the API link provided in the question itself.
This data is available for sale here
