I recently found a Nandi Bear Passport Sticker inside the front cover of a book that I purchased at a used bookstore.
What do I do now?
The first thing that you should do is visit NandiBear.com and enter the book’s unique Nandi Bear Passport Number and see where the book has been in the past.
The second step is to get a digital Nandi Bear Passport Stamp for your book. This will let others know of the book’s new location and how you personally acquired (e.g., bought at used book store) the book.
There's nothing that you need to print out or affix to your book. Your stamp is digital and will be attached online to your book's passport number. All that you need to do is login at Nandibear.com and click on Get your Passports stamped (PLEASE!)
Later on if you decide to donate, gift or sell your book you should get another stamp which will let others know that the book has again traveled!
