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
