Just to make it explicit, if I understand Dr. Vickery correctly, do
citation search forward--using _Science_Citation_Index_ !

(I love to spread the gospel re SCI, a neglected or sometimes misused
wonderful database)

OR, if there is an alternative database for this kind of search, I'm
interested in learning about it; every little bit helps.
