To give some idea of where we are...
The Great Brain books - probably ok. Some parts are likely to be deemed "too scary", but there isn't any particular tension to most of the books.
Encyclopedia Brown books - These are fine.
Charlie and the Chocolate Factory - Possibly too scary if he wasn't already familiar with the story, what with things happening to kids.
Peter Pan - Probably too scary, what with Cpt. Hook and all.
the Henry and Ribsy books - Probably ok.
James Herriot - Almost certainly ok.
Tove Jansson's Moomintroll books (Comet in Moominland is the first one.) - I have Finn Family Moonintroll on the shelf right now, actually. I don't remember enough about it to be sure it's properly non-scary, but I think it is. He doesn't like the looks of it, but I may force it

. I have a feeling Comet would be too scary, what with the comet preparation and all, but it's been 20 years or so since I've read it.
Alice's Adventures in Wonderland - Officially too scary, from the first chapter. We tried this the other night, and it was actually the inspiration for this post!
Charlotte's Web (sad, but not scary) - Already read it to him, but could be too scary.
Stuart Little - Probably ok.
The Trumpet of the Swan - can't recall it well enough, but probably ok.
Half Magic - Just checked it out of the library

The Wonderful Wizard of Oz (could be scary for some kids) - He has officially declared this too scary.
Winnie-the-Pooh and The House at Pooh Corner - these are fine
The Little Prince - Not sure
Mary Poppins - Probably ok
The Secret Garden - too scary, between parents dying and mysterious noises and all that
The Black Stallion series - the first book quite likely starts off too scary
The Phantom Tollbooth - No clue. I think it would probably be ok, but if I remember right it has a lot of the bizarre stuff that seems to bother him.
How about the My Father's Dragon series? - these are ok
Books I haven't listed I'm not familiar enough with to comment on, but I'll look into them.
Thanks everyone
