Q - Many Christian publishers want authors to have an agent, so how do we break into one of these publishers when we don't have a string of book credits to get noticed by an agent?
A- Although many of the major publishers now require that you have an agent,there are some who do not, plus a whole lot of others that do not require an agent. The market guide lists about 450 Christian book publishers, so it's only a small proportion of those that want you to have that agent. If you don't have any book credits, try those that don't have that requirement so you can start building up those book credits.
Another possibility is to attend a conference where there are publishrs and agents in attendance. If you have a good book to offer, then both the publishers and the agents may be open to your project. There's no better way to get the attention of either that to be able to sit down and present your book idea one-on-one.
