This is a really simple WordPress plugin that adds a sidebar widget. The widget has your book's title, an image of your book cover, and links to places to purchase the book at various retailers (i.e. Amazon, Kobo, Nook, iTunes, etc.)

You can upload your book cover image (or choose it from the WordPress Media Library if you've already uploaded it), enter the book title, and add links to 5 separate vendors:

• Amazon
• Nook
• Kobo
• iBooks
• Google Play Books

A widget for that book appears in your sidebar with links to all of the vendors you entered. You can add as many book widgets as you would like.

• Inclusion of book price
• Possibly the ability to add additional vendors
• Customizable image size for the book cover image
• Modifications to aesthetics

Eventually, you'll be able to install right from within WordPress. However, while in development, you do it this way:

1. Download the latest stable version
2. Upload the plugin files and images to /wp-content/plugins/book-widget directory, or install through the WordPress plugins screen directly
3. Activate Book Widget from the Plugins section of WordPress
4. Add a widget for each book you want on your sidebar.
