A newly typeset and printed copy of Alice in Wonderland does have copyright protection. The presentation has transformed the (public domain) text enough to qualify for protection. Someone chose fonts, letter sizes, line lengths, book size... You can't go making photocopies of that particular work and sell them without infringing.
You can, however, take the original text, which is now in the public domain, and typeset and print your very own Alice in Wonderland book. And now you hold a copyright on a presentation of Alice in Wonderland.
