Agents of good reputation have no shortage of material. So, if an agent contacts you, be very wary. I t probably means they have a shortage of material, which probably means most authors won't send them anything. N ot surprisingly, publishers come in two varieties as well. There are a few who would love to take your money and send you a load of books to sell yourself.
T hink about it.
Well, I've sold books, and I've written them. Personally, I prefer writing them, although selling them is easier money. For instance, if you are a public speaker and enjoy a fine following, you can publish your own book in a couple of months and have it available at your seminars. If you are known to a nice niche market, you might know you can sell your book, while it may prove difficult to convince a publisher of the fact. The best book we've found so far on Self-Publishing is by Christian Author Athena Dean.
