I've said this before and I will say this again. Always research before you sign on with someone. I've heard many tales of people who were sorry they signed with certain publishing companies. I started out research as well.

Originally, I had sent out a few queries to places that didn't require an agent, need to see a market for my book or wouldn't take talking animals (yes, some refuse). I got accepted by three companies right away. I can't tell you how excited I was. I then thought maybe I should be checking things out more and I was correct to do so. I found a lot of these companies had complaints or were listed as scams. Now I will not mention names but I will tell you that one company was said to make money from the authors who had to buy the books at a high price. The others, they were in it for the money and results weren't always good. One apparently didn't pay it's authors their royalties, many had unsatisfied customers and the list went on and on. It was then that I began looking into print-on-demand services and found one I liked.

It doesn't matter where you go or who you go through, look them up, research (keywords after their names: scam, complaints, etc.) because signing up with them could be the biggest mistake of your life. The same goes for traditional publishers. It doesn't matter who you go through, look into EVERYTHING! Even if there name doesn't show a scam, doesn't mean they are good. Be careful and do your homework.

What kind of things should you look at:

1. Are they legit? - Do they have a business website, contact name and number?
2. Are there any bad remarks about them out there (keep in mind that there are some companies out there who will try to hide it. I know of one who sues at any bad mention of their name)?
3. How much will it cost you to buy books? How many do you have to buy?
4. How much will you have to sell them for (look online and see what other books that size go for and remember that big places like those who make "Berenstein Bears" etc. can afford to charge cheaper so exclude those).
5. How many other books do they have out?
6. What do they offer?
7. Do you still own the rights?
8. Is there a contract and if yes, is it for you?
9. If a person went through the company, did they bring their next book there?
10. Are the prices to publish the same as others? Do they offer the same?

Never sign up with a company right away. Look into a few. BE CAREFUL! You could be giving away your dream!

Traditional publishers are those companies you frequently see on the back cover of the books in stores. They pay you for your writing and not the other way around. Here is a list of some known publishers, what is required to submit your manuscript and the sources for this information. Below this you will find Traditional Publishing Pros and Cons as well as a service video. Please keep in mind that the information provided below was relevant at the date of this post. In no way are we trying to tell you which way to go or that these publishers are bad. This information is here for your use to help you look into which route is best for you.

Traditional Publishing Pros

• If they take you, you are paid a royalty check.
• They market your book for you.
• Your book is in the bookstores plus widely distributed for you.
• Added credibility as an author.

Traditional Publishing Cons

• That royalty check has to be paid back through your sales. You won't receive any more money until it has been.
• It can take up to 6 months after submitting your manuscript, to find out if they are interested or not.
• The process is slow so it will take awhile before the book is on the bookshelves.
• Royalties are anywhere from 10% of the book or $1 per book. This is lower than self-publishing and print-on-demand.
• They own full rights to the book which means they have control over everything including whether it stays on the bookshelf. You won't be able to publish it again.
• If your book doesn't do well, that will go towards your credibility as an author as well.
• Unless your book becomes a best seller (this doesn't happen to most people), you will never get rich.
• Some traditional publisher will not take on an author without an agent. Those that do prefer to see the market for your book and/or a writing resume.
• Traditional publishers are less likely to publish children's books because there are so many out there and they rarely take on a book series because they don't want to commit to books that may not sell.
• If your first book doesn't sell well, they won't publish another book for you.

Things to Beware of:

1. Type the publisher's name and then the word "Scam" after and read any articles you may find.
2. Anyone saying "starting at $" is listing the lowest price possible which usually doesn't fit most page counts.
3. Before publishing through a self-publishing company, find out what price you will have to set your book at to make money.
4. There are certain companies out there who simply want your money (or there is a catch) and will make it seem like they are offering you a great deal or are like traditional publishers but they are not.

Please note that while at the time these were published, they were true. In the future, they may change. The warnings above in no way are meant to discredit the above companies.
