> Do we have adequate copyright information, for instance?

I've only looked at one file:

And it looks like you could improve the copyright info:

Here the copyright claim is that the author died more than 70 years ago, but there is no illustrator death date listed.  So to verify the claim, we would need to do some research.  So if you have the date of death, and if the book was published outside the US (here it was apparently London, UK), please provide it.

Also, note that the current copyright template says (after a big warning sign): "You must also include a United States public domain tag to indicate why this work is in the public domain in the United States."  In this case you should use http://commons.wikimedia.org/wiki/Template:PD-1923.
