Leigh Dodds included iSpecies in his recent post on the scientific paper as modern palimpest. He writes:
iSpecies is a nice example of a science "mashup" that illustrates an alternative search interface for finding related content. I used the false results that can appear when performing simple keyword searches to reinforce the need for standard identifiers. (The need for a common, scoped identifier for authors, is a particular hobby horse of mine).
Among the false results is the image of oil tanker (among other things) that Yahoo provides when searching for "Apus apus."
