Determine the type of PLR e-book you wish to promote, and purchase depending on your business needs. If you have a website to promote business, choose E-books that fall into the niche of your business. Such books may include investment guides, fitness, self-help, travel, or outdoor sports.
Conduct an Internet search using Google, or Yahoo and narrow down the type of PLR E-book you need. Use keywords such as PLR and the type of book you're looking for. For Example: plr fitness, or plr investment.
Look through the choices. Many e-books are sold outright, while others are free, which is great if you're working on a tight budget.
Network with other marketers on forums, or though social networking sites such as Facebook or Twitter, to find the right PLR E-book that you need. You could find another seasoned marketer out there that can point you in the right direction, or recommend a site that has a ton of free PLR E-books such as FreePLRebooks.net or PLRDownload.com.
