The authors review a number of approaches to "just for you" service. They s
uggest that this concept offers opportunities for library and information s
cience (LIS) programs to extend their reach by engaging domain experts who
will develop services and architectures grounded in communities of practice
. They propose a unifying framework for an extension of LIS education and t
raining and suggest that this be labeled "the ethology of text"-an extensio
n of Nardi's concept of "ecology of text."(1) The proposed framework can im
prove understanding of domain experts at work, if core elements of existing
LIS programs (user needs, relevance, indexing, classification) are revisit
ed, unified, and interpreted in the context of local practice. The paper co
ncludes with some observations on professionalism, which address problems o
f linking communities of practice to knowledge architectures designed by in
formation professionals outside any specialist domain. Outline suggestions
for a curriculum that can enhance the performance of texts at work in a giv
en domain are also provided.
