SERVICE MARKETING HAS IDENTIFIED THE CUSTOMER or user as the most critical
voice in assessing service quality. Before assessments can be made of servi
ce quality in ARL libraries, it is essential to investigate what connotes s
ervice quality in the minds of library users. Today the dimensions of libra
ry service quality among the ARL cohort are not fully understood from the u
ser perspective. The LibQUAL+ project attempts to identify those dimensions
and measure the gaps between expected service and perceived service in eac
h dimension. This article describes the interviews conducted with users of
research libraries across North America in the first round of work on the s
till-evolving LibQUAL+ instrument. The interviews provided a rich pool of i
nformation about the users' own behaviors, their perceptions of what a libr
ary should provide, and their interactions with that important resource as
they pursued their diverse objectives at their respective universities. Ana
lysis of the interviews contributes to the identification of the dimensions
of library service quality; which will be further tested in future iterati
ons of the LibQUAL+ tool.
