Quite possibly, you’ve been told of public domain publishing as a pathway to earning money online.  I am here to tell you about a twist on it that can have you bringing in extra income almost right away.

First, though, let’s review the fundamentals. As you may know, many books and other works have entered the public domain (fallen out of copyright) and can be republished, in any form, by any person who wants to do so. In the United States most works published through the year 1923 are now considered to be public domain (“PD”).

If you discover a PD book you think people would purchase if it were republished, you could reprint it as a physical book and sell copies on eBay, Amazon or your own web site. Some enterprising folks have done this with old correspondence courses and other non-fiction, how-to type materials from years ago.

On the other hand, you could repackage your PD find as an e-book and make it available for downloading, for a price. This is probably the more usual way that people are earning money these days from the public domain.Again, how-to, self-improvement and other non-fiction works will usually prove to be the most profitable.

Now about that little twist I mentioned.  The method I prefer is to make PD books freely available on the web, and place advertising on their pages. Strictly speaking, then, you are selling ad space, not the book itself.

A few years a guy named Steve Smith heard about an odd book from 1892 that combined a time-travel-type tale with a story about golf. Its title was Golf In the Year 2000.

After some looking, he was able to find a facsimile edition of the book that he could acquire for $10. He scanned the pages, converted them with OCR software, and posted the whole book on a web site he had registered just for that purpose.

He went further than that, though. On his web pages, he surrounded the text of the book with Google AdSense and affiliate merchant ads. This enabled him to make money from visitors clicking the AdSense or buying things. By the way, if you’re curious you can view his site at www.golf-in-the-year-2000.com.

Steve’s online edition of Golf In the Year 2000 attracts a steady stream of golf enthusiasts, science fiction fans, Victorian literature lovers and the simply curious, he reports. And the ads on his pages bring him money!

This is certainly an idea that could be copied by others. Public-domain sources are abundant nowadays.  You might be able to find an appropriate book in one of the many web-based PD archives, preferably one that not many other people have discovered yet.

One good thing with this idea is that the book you showcase (and use to earn ad revenue) need not be restricted to non-fiction or how-to.As with Mr. Smith’s strange little science fictional golf gem, it can simply be something that will bring web surfers to your site, for the novelty if nothing else.

You could also look in used-book stores to try to find something rare enough not to have made it to the Internet at all.  In that case you will probably need to buy a scanner and some OCR software to get the text into your computer.

Public domain publishing is indeed a potentially lucrative area.  And, how you “repurpose” your PD finds is entirely up to you.  That’s what makes it so fun, as well as profitable.

This method of publishing public domain material is also described in this article, along with recommendations for further reading.
