The Redmond, Wash.-based company announced that it will release the beta version of its Live Search Books application tomorrow.
This is an important part of the company's strategy to turn its Windows Live platform, which it just took out of beta in the last few days, into a hub of experiences that create customer loyalty, thereby driving incremental advertising revenue gains.
Currently, Live Book Search returns queries on books that are no longer protected by copyright.
Next year, it will include books that are currently under copyright protection as well.
That, Microsoft hopes, will make its users come back more often.
