Book Test Library - All Books + App Access

Book Test Library Subscription gives you access to the word location of HUNDREDS of titles, letting you perform Book Tests in ways never before possible!

With your subscription, you get access to the Book Test Library App, which is a app that lets you pick up a paper book and know ANY WORD from ANY BOOK in our library of HUNDREDS of books.

It's the fastest way to secretly look up any word from a book during a live performance. Just enter a page number, line, and word, and the result appears instantly. All lookups happen offline on your device, so there's no lag and no internet needed.

You also get access to the Book Test Library integration in your favorite magic apps, including Calculon, Notarized, and more from ThoughtCast Magic and others!

You can also purchase single edition books as well, and have access to them without a subscription. Browse all the titles on the ThoughtCast Store in the Book Test Library section of the site.
