As a Public Domain researcher, determining whether or not a book, image, audio or video resource is in the Public Domain can be a daunting task, unless your best friend happens to be a copyright lawyer. I have discovered some secret ways to "allow" others to do some of that copyright research for you, at no cost to you. Now, I am not a lawyer (and do not play one on TV), so I do not offer this information to you as legal advice, but this approach has saved me a lot of time and effort and has proven extremely valuable in my own Public Domain research. Here is the "secret" strategy: Discover what other information publishers are already selling, then obtain your own copy and sell the same thing. Monkey see, monkey do. Here's what I mean
I'm sure most of you have heard of Dover Publications. I doubt that there is any company who has developed and utilized Public Domain content more than Dover Publications. Let's say you see that Dover has republished an older publication that would fit well within your niche market. Chances are very likely that since they are publishing it, they've already done the copyright research to determine that the resource is indeed in the Public Domain (as a matter of fact, I'm quite certain they've done that research). Now that DOESN'T mean that you can order a copy of Dover's product and then reproduce it for your own purposes. They have their own version copyrighted or protected by license. What it DOES mean, however, is that you can locate your own original copy of the resource and develop it with some confidence that it is copyright-free. I always say that you cannot look for something that you do not know exists. Researching Dover's database (also know as their catalogs) helps you "find" those gems, of which you were previously unaware.

To maximize your research results using these types of websites, be sure to:
1. Take a look at the products they are selling. Many of these are based on Public Domain resources, and in some cases, might even be exact reprints. The products they offer will give you a good idea of just what is available...think about it...there is a reason why THEY are selling it, right?! And it certainly aids in your quest to have actual titles for the books that fit your niche.
2. Pay attention to the information they offer about the books or products they are selling. This is the same information you can use to locate your own copy. Often they will include the title, author, year of original publication and more. Armed with that information, you can head over to Abebooks or Alibris and search for the book there. You can even plug the info into your favorite search engine. Who knows, the book may turn up being online. Remember, there are 85 million Public Domain books out there.
3. Use their resources as a bibliography to discover obscure titles by authors that may not be listed anywhere else. In some cases, you may discover a complete listing of titles by your author on these sites. Use this list as your own checklist to find the books that will best serve your niche through Ebay, Abebooks, local used bookstores or libraries (or one of many other online or offline places).
Whatever you do, do NOT underestimate the value of this type of Public Domain research. Many of my own greatest Public Domain discoveries were made at some of these types of sites. Take time to get to know these types of websites - research them. You just might strike gold!
