I used to think that once a book had been published it would stay published for ever, but sadly that's not true. The average publication life of a book is about 18 months. Publishers want to make room for their new books. Even if a book is still selling in reasonable numbers they won't bother to reprint. They once caught me by surprise and stopped publishing one of my favourite books WHAT IF...? before I had a chance to get hold of some copies. (Blighters!)
Happy Hippo, In the Night, What if? Horrible Crocodile and Busy! Busy! Busy! are now only available second hand. ( I have a few second hand copies of Busy Busy Busy which I am willing to sell to anyone interested. Send me an email and I'll give you more details. )
They sometimes appear on Ebay.
Two other good places to get hold of second hand Jonathan Shipton books:
These sites search for books from booksellers in both this country and the
U.S. (the only real difference is that 'mums' become 'moms' )
