You can recognize a book by the ISBN or eISBN number—this number is always unique. A quick way to double-check is by copying/pasting the ISBN number in your Google search bar. After hitting enter, that exact book should pop up in the search results.
If you’re not sure that you have found the right book, you can check if the ISBN number is the same as the number on your curriculum list.
Just a quick note: the ISBN and eISBN for a book with identical content in physical form will look differently. Don't be alarmed. We may have the book you're looking for, even though the ISBN or eISBN doesn't match the one from your curriculum.
