Thanks Alex - I'll look for that.

My only quibble is - and it's my own fault for not looking before I bought - some titles I'd like aren't available on the kindle. Apparently JK Rowling has a distrust of all ebook platforms and won't let them be licensed. For the most part I find about 80% of what I'm looking for is available. There are just a few titles I want but can't get.

Arthur Weasley would be disappointed.
