Any links to match REFERENCES?

[Russ Lewis]

The REFERENCES file notes two articles to read, "Static Semantics in
Compiler Error Recovery" and "Efficient Construction of LALR(1)
Lookahead Sets".  I can't find any links to anyplace on the web where
they can be found.  Does anybody have links to these, or to similar
documents that would be a good starting point for learning Bison's
design?
