Amazon has become a strong platform for publishing books, anyone can write something and then publish it there. But how do we know which books are junk and which aren't? I mean with the number of pdf files out there from unknown authors increasing doesn't it make it difficult to actually find the right book? I have been working on a book for a long time would it be wise to place it on Amazon? Or do you guys suggest that once I am done with the book should I look for a publisher to actually publish it for me? Which one would be better to do?
