Some years ago, during a discussion in the ASTR Executive Committee about the relevance of the Theatre Library Association's participation in ASTR, a scholar on the cutting edge of contemporary theory is reported to have asked a TLA representative exactly what it was that libraries were doing to support postpositivist research. No one remembers what the answer was (it was evidently satisfactory), but I recall thinking that if I had been asked the question, my own reply would have been that libraries weren't doing anything at all; that the business of the library was to preserve the evidence as well as it could and provide access to it, so that scholars could make use of it in whatever manner they chose.
