I have. *thanks to Mr.Urges* I know money would be part of the reason why this is done but there has to be better reasons, right? As in other reasons for publishers or authors to do it.
Well, after a few knocks on Mr. Google's door, I found a few answers.
1. They would like to boost the sales of the book...and yes, they want more buckz.
2. There is already another book with the same title in the market and they wanna avoid confusion.
3. To fit in the society better...which leads to better sales of course. Many UK books have been retitled in the US...and maybe vice versa.
4. Could be a plagiarized book. i.e. The same book was written by a different author under a different publisher sometimes even in a different country BUT the new author claims it as his/hers. Well, I bumped into this if you'd like to read further on how US and UK handles book plagiarism. :(
Anyway, here are some books I know with 2 titles.
The Secret Dreamworld of a Shopaholic == Confessions of a Shopaholic
Shopaholic Abroad == Shopaholic Takes Manhattan
Where Rainbows End == Rosie Dunne I Love, Rosie
If You Could See Me Now == A Silver Lining
A Place Called Here == There's No Place Like Here
Harry Potter and the Philosopher's Stone == Harry Potter and the Sorcerer's Stone
I'm sure there are a lot more out there. I'm also sure there are more reasons why a book is retitled. Anybody who has answers other than the points I've mentioned above, feel free to add in the comment box. ;)
Possible book with answers; yet to find the ebook...hihi
