A friend of mine (and the person who taught me about beekeeping) is writing a book on propolis, and has asked me to ask if anyone has any suggestions for information sources on propolis. I have tried to consult the BEE-L archive, but without success (any help on this greatly appreciated), but would also be interested in any other sources/information/anecdotes etc that people may be willing to share. Thanks Mark Walford (only one hive so far - an extreme novice) London, UK
