When I was at School in the UK, I read a book which was a sort of encyclopedia' of aliens, and I have been trying to remember it's title. It was a large-ish book (a4-ish) hardback with a black cover and silver writing. The picture on the front was of a large, green tentacled creature with a yellow eye which was consuming a space-ship. Inside it had full-page pictures of various aliens, including the above creature (called a 'Space Barnacle'(?)), angels (which it described as 'grey-skinned, winged humanoids with purple 'radiation' halos')and I think one of the authors might have been Clive Something or other.
I know this is rather vague and a long shot, but does anyone else remember such a book. We had it in our school library when I was a kid, but I've never seen it since. It was rather cool, though.
Any chance this rings a bell with anyone? or have I dreamt it?
If anyone has any suggestions, I would be most grateful...
