The growth of knowledge in any discipline depends on discursive practice fo
r the assertion of claims and the assessment of claims. At times, however,
that discursive practice may be ideological in nature. Ideology is here def
ined as being grounded in efforts at domination-the ascendance of some idea
s over others. Examination of tire incidence of ideology in discourse is ne
cessarily interpretive; part of this article explores the application of he
rmeneutics to the analysis of discourse. A set of examples of discursive pr
actice in library and information science (LIS), purposely selected, is exa
mined for ideological intent. Ultimately, the aim is to demonstrate that so
me discourse is ideological in nature and purpose, and to point out tile im
plications of such discursive practice for knowledge growth in LIS.
