Please help with adding this edition

[Joanna]

Hello Wonderful Librarians :)

I need your help yet again. I'm currently reading 'A Tale of Time City' by Diana Wynne Jones. I wanted to add it but I cannot find the edition I have. The ISBN number of my edition is 978-0-00-675520-3
but this directs me here: http://www.goodreads.com/book/show/10...

This edition has a different cover and page count to mine. For some reason the only place I could find the edition I own is the publisher's website:
http://www.harpercollins.co.uk/Titles...

So how would I go about adding this? Btw, the page count of the book I have is exactly 400 pages (I don't think that's mentioned on the publisher's website).

Please help and thank you in advance!
Joanna
