The final .zip file on the site I mentioned above contains Child texts 1-305, but be warned; the link doesn't work.  This one should do:  http://www.colorado.edu/ArtsSciences/CCRH/Ballads/text.ZIP

It's a 1087 KB file, and will need to be given a .txt extension when unzipped.  As MMario said, there is a lot of stuff to strip out so that it can be easily read.  As it's a concordance, they haven't transcribed the notes.
