Kimberly Maul of The Book Standard divulges that Google will soon be unveiling a new marketing component of the Google Book Search Partner Program, according to Web Pro News.

The pending program will empower publishers to add a co-branded Google Book Search tool onto their sites at no cost if they're part of the program.

The Book Search tool enables customers to sample written content before making a purchase.

McGraw-Hill is among the first publishers to implement the tool. They are also testing Microsoft's Live Search for books.
