I have questions for those Kindle users out there. I noted a comment in another post that a Kindle is so cool because you can have hundreds of books in your hand all at once.

So, at this point in time, how many books are actually available in digital Kindle format? I note that most new books coming out are available, especially on Amazon. Especially fiction.

How many older books are now available? And is there a source to be able to query to find out if a certain book is available?

My issue is that I read a lot of obscure history. I like to acquire actual dated books of vintage age to read what the attitude of the day had to say about historical events before the modern revisionism has set in.

It would be great to reduce the load of books, but I suspect there is a limit for how many obscure tomes are available digitally.

All thoughts appreciated.
