[Air-l] Internet Surveys: One or Many?

Folks, I have a quick question (I think) for the group with regard to internet surveys. Does anyone have an opinion and/or references to literature about whether the implementation of several small surveys is better that one very long survey? When I say 'better', I mean a positive effect on survey responses? Thanks Kylie ------------------------------------------ Kylie J.
