[REBOL] select question

[bemerson]

I have a series with multiple identical entries, but different values:

[ "book" "The Hobbit" "book" "The Stand" "candy" "Mars Bar" "candy" "M&M" ]

I want to search the series for each occurrence of say "book" and then 
evaluate it for a match.  How can I do this?  Or, is select perhaps not the 
right hammer to beat this puzzle with?
