I was wondering if either might be available at Google Books, but they aren't. But I did find The music of the waters: A collection of the sailors' chanties, or working songs of the sea, of all maritime nations, by Laura Alexandrine Smith, 1888.
Oh, and check out The Shanty book.

You can purchase the Seven Seas Shanty Book through bookfinder.copm, but it ain't cheap.
