ABSTRACT:
Part I of this three-part paper discussed the genesis of
the law formulated by Donald J. Urquhart on the use of scientific and
technical (sci/tech) journals through interlibrary loan and central
document delivery. It concentrated on the study of such use conducted by
Urquhart in preparation for the establishment of the National Lending
Library for Science and Technology (NLL), which became the central document
delivery library of Britain. The focus of Part I was on the statistical and
probabilistic bases of this law. In Part 2 the emphasis shifts to how
Urquhart utilized probability to develop and manage the NLL's sci/tech
journal collection. Urquhart based his collection development and
management policies on a high-loan core of journals, causing the stability
of sci/tech journal use over time to become the main theoretical issue.
Part 2 analyzes the controversy over this issue between Urquhart and his
successor, Maurice B. Line.
