Biologically inspired design is an important emerging movement in engineering design. Finding relevant biological sources of inspiration from existing biology literature is one of the important challenges of this activity. We conjecture that annotating biology articles with lightweight Structure-Behavior-Function (SBF) models is one way to address this challenge. We present Biologue, a social citation cataloging system that allows its users to gather, organize, share, and most importantly, annotate scholarly articles with SBF models. This feature not only allows the implementation of search mechanism that is more targeted to the needs of designers seeking bio-inspiration, but also helps designers make sense of the articles returned by the search mechanism.
