There is a method called DNA shuffling mutagenesis by a guy named Willem
Stemmer, published in SCIENCE and/or PNAS in late 1994/early 1995. He
takes a PCR fragment, DNAse I digests it and purifies out 50 - 200 bp
fragments, then run PCR cycles with NO primers to let the fragments
anneal and primer off each other, introducing recombination errors as
well as PCR misincorporation errors.
Sorry, no specific citation, you'll have to look for it. :(
