ABSTRACT
One of the most significant challenges in constructing a handbook that proposes to display an area of study is to divide prominent, diverse kinds of work into coherent categories in such a way that common themes across those categories are made visible, while giving room for each subfield to make obvious its distinctive contribution to the enterprise. A further, just as significant challenge is to look across work that, although recognized as just as influential, cannot fit comfortably within any of the categories. As is probably the case in any interdisciplinary area, there were many more outstanding programs of research and theory that have an important bearing on the central concerns of LSI than could be fit into a volume of the proposed length. It was also increasingly difficult, when those projects were arrayed together, to find a common thread among them that would allow a section labeled something other than "Miscellaneous Excellent Work in LSI."
