I look at regex syntax reference page here
http://www.regular-expressions.info/reference.html
but there's no definition of the \1 operation ?
do I need a better reference page or book ???
what's a good book to learn from ( intending to use more regex in both sigil and calibre ). I'd prefer an ebook that I can put onto my kindle.
