They allow you to be on another website and do a search of the PBS database without going to the PBS site to do it.
For example: if you are reading an online newspaper or blog, and you see a review for a book you might be interested in, you can simply copy-paste the title or author or ISBN into the PBS Search field at the top right of your browser, and search PBS to request the book, or add it to your Wish List.
You don't have to go to PBS and enter the information in the Search there; you can do it from the window you are on!
How to Use our "Book Search Plugins":
Go to the Browser Plugin Download page here (linked from the bottom of any page on the site)
Click to install the plugin for the browser you use
After you have done this, there will be a dropdown menu in the Search field on your browser (at the top of your browser window, to the right of the space for the URL/web address)
When you are on any site, you can click the "down triangle" in that Search field and choose PBS from the list of Search engines to use
When the PBS logo appears in that Browser Search field, anything you type in there will search PBS automatically.
You can leave PBS as the default search engine in that field, or choose it each time from the list.
