It’s almost like in a bookstore: allow your readers to thumb through your book even before they purchase it online. This is made possible by Amazon Look Inside!, Google Book Search, and Libreka. In this way, prospective customers are motivated to buy your book as they are free to browse through a few passages without having access to the whole content. An additional full-text search helps every reader find the right book - even where uncommon special-interest themes are concerned. However, a full-text search will never be a substitute for actually reading and buying books as it is impossible to view the complete content of a book when searching.
