Question

What's the proper way to reference a book from Project Gutenberg (MLA format)? It doesn't have all the information for the book format, but it was originally published as a book, so the web page format doesn't seem right.

(If it matters, the book is Lewis Carroll's "Through the Looking-Glass")

Answer 1

Since you got it from Gutenberg, not the print copy, you'll need to cite Gutenberg:

Include as many of those 13 items in the list, in that order. (No one can include all 13, but include what there is.)

If you want to give it a try and post it here, someone will be happy to check it for you.
