Ambiguous Series Numbering

[Priyadarshni]

This book is placed on #13 in the series, but titled as 'Piano Lessons Can Be Murder - 12 '

I have searched several sources which note that this is #13 in the Classic Goosebumps Series, and I actually own a copy which is numbered #12 on the spine. What do I do about it? Does anyone have any suggestions?

They were probably numbered differently in different markets, so both are correct. Sort of like how the first Harry Potter book was renamed in the US. It actually isn't uncommon, especially with childrens books where foreign publishers may skip a book if it is for instance very culturally bound and difficult to translate.

If you can find a reliable source that lists the other numbering, we could add another series. Otherwise, keep the #12 on your edition and add a librarian note to say your book in hand is clearly numbered differently.
