I just got a new "coin" book, it is a book about a father that helps his kids collecting coins via e-mail. Its is great fun reading it and interesting to see how they use e-mail to get all the current countries in the world.
There is a lot of information about how to contact people, and how to get in contact with people on small islands.
On the coin side the book is very limited there is no information about the coins they collect only on how they collect them.
I can recomment the book if you enjoy nice stories and interesting facts.
the book can be ordered online at

but i got mine from my local coin dealer
