A couple of things about the book online, I am so ignorant about computers and stuff, but let me offer these.

When I bring up the google books page, there is a place to enter a search; maybe your page does not have a search feature? If it does, "Songs of a Roving Celt" will pull up the file.

The "about this book" link on said site, discloses that the source for the digitized book is the University of California -- no link thereto, however.

What is built into the URL for the digitized book file,
is something called a BibTex ID number:
BibTexId=j7NBAQAAMAAJ    I have no idea what it is, though.
