The first thing entrepreneurs usually think about when dealing with public domain materials is text material, specifically books and reports. Most public domain dabblers already know that the US government has thousands of copyright free publications and encourages the distribution of them, or that Project Gutenberg hosts thousands of free texts that can be used for product creation. But there's a whole treasure trove of delights you can find online and off in that copyright free world of public domain, including software, audio, film, and art. And yes, they can legally become part of your next product!
For instance, sites abound with free to use audio books, music, radio shows, and sound effects as well as sheet music for various instruments. You are free to use all the true non-copyrighted materials to create new products and sell them as your own.
Some developers have placed their software programs in the public domain, although using it can be a little tricky. You need to know how the program works and then hire a coder to make it work specifically for your own purposes. So unless you're a programmer, it would require an investment to change the program to meet your specific needs.
Please note that not all freeware is public domain. Always read the licenses and terms of use to make sure that what you're redeveloping is indeed in the public domain.
Hundreds of thousands of royalty free photo images are hosted online, waiting to be used in your next book or as part of your business brochure or product. Many professional artists and photographers have donated their works to the public domain, so you can find some very creative images. Again, you'll want to check the licenses of each individual photo in which you're interested, just to make sure it's copyright free.
As far as sheet music is concerned, you can find music for all sorts of instruments on the web, so think beyond the keyboard. Also, some old magazines, like Etude (issues before 1923) have sheet music that can be compiled into new collections and sold. All the treasures aren't online, so check out some antique stores for the best buys!
Whatever your fancy- whether comics, radio shows, music, articles, books, software or movies - a virtual library of public domain items exists for free and legal use. Wise entrepreneurs are making profitable use of this material, repackaging it for the modern market. Why not capitalize on the treasures you find in the public domain?
