Searching for public domain works can be a tedious job and take several hours just to find one or two good publications.
There are hundreds, if not thousands of quality databases online you can use to search for public domain content, but are you aware of the places offline you can visit starting tomorrow morning and walk away with a handful of public domain publications you can duplicate.
The best part is you don't even have to purchase the books.
I'm referring to your local public and university or college library. There are thousands of public domain books right on the shelves waiting to be revived.
This is by far the simplest way to get your hands on hard-to-find public domain works.
I did a quick search of my libraries database online and found over 20 interesting publications I think will be good sellers online such as "How To Speak And Write German", "The Official Guide To Knots And How To Tie Them", How To Play A 5-String Banjo", How To Star In Baseball", Gemcraft: How To Cut and Polish Gemstones", Kites: Hot To Make and Fly Them", Your Lawn: How To Make It and Keep It", "How To Make Your Own Picture Frames", and the list goes on and on.
Once you find public domain material you're interested in conduct a quick copyright search to ensure these publications are in fact in the public domain.
Then visit your library, sign out the books and begin using the content. There are companies who offer scanning services relatively cheap so you can create a digital version.
You can also create audio and/or video portions of each publication and sell the videos under your copyright.
So now you have enough information to start your public domain search offline starting tomorrow morning.
