Mark, I don't see anyone being rude. You gave a suggestion, and others said they didn't think it was a good suggestion for some reasons, and now you've said they are because they have habitat information... So from all that, the OP can decide if they want to but these books or not. From there lets move on if anyone else has other suggestions.
Edit: And side note, BigBella edited his first reply to you a few times, but none really changed the point of his post.
