One of my books is titled Warfare Today. It has no copyright date or date of publication in it at all...

Tie in to the topic (thought I'd really gone off my rocker there, didn't you?): Going from the pictures of the equipment in the book, it dates from the early fifties if not the late forties. I can work this out because of haveing other history books and knowledge to draw upon, I can work out that the book is out of date. With Modern Astronomy and the like, you don't know how current the book is unless it had the copyright date and date of publication (which a lot of people don't even pay attention to) so you could have people mis-educated about the subject and not even know it....

edit: Part of my book collection consists of old science books and text books--it's fascinating to see how science has evolved over the years to make more sense of the universe around us...
