Give your visitors the freedom of choice with BookLinker, a WordPress plug-in that converts existing affiliate links into a list of book resources: Amazon, Powells, and IndieBound affiliate links, WorldCat library searches, and LibraryThing book pages.
There are a lot of reasons to break free of the Amazon monopoly on the Internet–see my thoughts here–but the best reason is that your visitors should have some options for where they get their books. With BookLinker, you provide your affiliate ID for the three primary book resources on-line, and select which links to display. Any existing affiliate links in your blog will be transformed on the fly to the links you’ve selected. No changes are made to the actual content of your posts, so if you choose to return to a single-affiliate mode, simply deactivate the plug-in or turn off the option to convert the affiliate links of your choice.
What it does
For each book link on a page or post, BookLinker will display a tasteful DHTML pop-up window containing an image of the book cover, and links to each of the book resources you’ve selected. The window displays only when a visitor clicks the link, and can be dismissed with the “Close” button:
When a visitor clicks one of the links, a new browser tab or window opens to the selected page. If you’ve provided affiliate ID information in the BookLinker settings, all of the affiliate tracking will be in effect.
BookLinker installs just like any other WordPress plug-in.
Copy the contents of the “booklinker” folder to a new “booklinker” folder in your blog’s wp-content/plugins directory.
In the administration panel, go to the Plugins menu and locate “BookLinker” in the list of available plug-ins. Click the “Activate” link, and your installation is complete.
If you have problems with BookLinker, you can de-activate it from the Plugins menu, or delete the “booklinker” folder from the plugins directory.
After you install and activate the plugin, go the Settings menu in the WordPress administration panel and find “BookLinker.” Click the “BookLinker” link to set your options:
Affiliate IDs can be entered for IndieBound (the network of local, independent booksellers), Powells (the giant Portland, OR, bookseller), or Amazon (surely you’ve heard of Amazon …). The IDs you enter will be used to build the affiliate links in the BookLinker window.
To display book covers, you’ll need an API key from LibraryThing. Without this key, BookLinker will still build the affiliate links, but it won’t show a book cover. You can get an API key by joining LibraryThing and requesting one at the API Keys page. It’s free and easy, and should you be so inclined it gives you access to some of the most interesting projects that combine the web with books.
You can choose which links to convert to BookLinker links, and which links to display in the BookLinker window. Again, it’s all about choices, and how your visitors interact with books and the web.
Click the “Submit” button after making your changes, and your set to go!
If you’ve already been using your affiliate program’s tools to create links to books, you don’t have to change a thing. Keep generating the links from the Amazon, Powells, or IndieBound affiliate pages, and BookLinker will take care of the rest.
If you wish to create native BookLinker links instead of starting with an affiliate link, you can use this pattern:
<a href="[isbn]" rel="BookLinker">My Link</a>
where “isbn” is the 10 or 13 character International Standard Book Number for the book you want to link. (Hint: the ISBN is prominently displayed on the IndieBound, Powells, Amazon, WorldCat, and LibraryThing pages for most books.)
If you want to selectively leave some links unconverted (for example, Amazon affiliate links to non-book items, or links to specific editions of books available only through certain retailers), simply add “rel=’NoBookLinker’” to the link:
<a href="[URL]" rel="noBookLinker">My Link</a>
Affiliate links with “rel=’NoBookLinker’” will be ignored by the conversion process.
And that’s about all there is to it!
Here’s a sample link, generated from the Amazon.com link builder and transformed by the BookLinker plugin into a link to other book services:
If you have questions, concerns, or feedback on this plug-in, leave a comment on this page or anywhere else on the site, or drop me a line. This is very much an early-alpha release, so there are probably bugs to be squished; I plan to make a more mature release available through the WordPress plugin directory after a little more testing.

Feel free to drop something in the tip jar:
And honestly, I’d be just as happy if you saved my tip by picking up a book at your local independent bookseller (check IndieBound for the one nearest you!). And say “Hi” to the bookseller for me!
