According to The Guardian newspaper, the market for self-published resources grew by 79% in 2013. Amazon are largely to thank for this growth, as the online company has been at the forefront of this movement.
Since the Kindle platform was launched, it became even easier to release your resource to the world. All that’s needed to release your ideas/facts/knowledge is a formatted book, an ISBN number, and an Amazon account. Customers will then come to you in search of entertainment or answers to a particular problem.
Of course, now the market has grown to such a level, even Kindle is no longer needed. They serve purposes away from making direct revenue. Some can be given away in order to secure contact details from a potential buyer. Others can be filled with your business’s details and offered for free in order to increase your exposure. The possibilities really are close to limitless.
