When buying books or extracurricular books wholesale purchase must take note of the five traps. One. Title Author too grandiose a lot of similarities "Office Office seeking effort" "can not see the X reasons" school libraries with this title of the book at the time of purchase must not be easy to buy, most of these types of books belonging to the marketing types, especially the pen name of authorship, but there is a save file is suspect. Second, too few books printed in the back of the book will have a general number of copies printed, in the current market environment, school libraries with books, 500 about the number of printed will basically lose money, if less than 30 are more likely to It is part of self-marketing. Choose books in time to pay attention, this is often the case with this book publishers are not very good, want to see the market's reaction before deciding printed less reason is because most badly written. Third, the pop charts are not necessarily good book many people will be selected according to Billboard charts books, they think we are looking to buy a certain book. But the fact is not the case with primary and secondary school library books, popular are not necessarily good. For the popular books, you may wish to put off, if it is still popular after a long time, then this book is worth a look, if you pop a few days disappeared, indicating that the book does not quite Okay. We are begging knowledge, to school, to work, to the teachers begging, begging to the students, to seniors begging ...... We are begging knowledge, he asked the others ", that is how to write, how to do it" seemingly active, in fact passive and did not mind the knowledge itself, but to use the time, I had no alternative but to ask someone else to libraries with, never take the initiative to understand it. To be honest, we are not high enough level of knowledge in the world, personally I recommend that you go to some of the large number of wholesale website to buy books of some books to mad intensively, certainly a great help for the future.
