Book publishers, in Sheffield, are involved in publishing books from the author's manuscripts. They are the intermediaries between the author and the book dealer. Rage of online book stores in Sheffield these days, and availability of many old books available on different websites, have made things difficult for the book publishers in Sheffield to create an impact on the customers for new books. Actually book publishers cannot overlook the fact that people can buy and sell used and rare books online. In fact, they are really unsatisfied with it, since sale of old and rare books online have started to affect their book sale negatively.
