Information and knowledge is key for authors that want to market themselves as authors and market thier books. Sometimes a author can't take off and attend book conferences and book events nationally, however, there are some great local book events and conferences worthy of attending. Of course it also depends upon what area you live in, however here are a few links to some great sites that you can view and from them you will find other great links and great ideas.
Another important part of marketing yourself as a author and marketing your book is through having your own authors web site, authors blog or authors media blog with contact information.
