Volume 22 introduces one of us, David Allen, as a new Senior Reporter,
although not as an author since David has contributed to Organophosphorus
Chemistry since volume 7. David replaces John Hobbs, who we thank for all
his hard work, not only as Senior reporter but also as author of the
"Nucleotides and Nucleic Acids" chapter. We have been fortunate in
persuading Rick Cosstick to take on the formidable task of writing this
chapter and we welcome him. Unfortunately we have again not been able to
include the "Physical Methods" chapter but we hope to do so next year.
