The paper reports a longitudinal analysis of the topical and methodological development Library Information Science (LIS). Its focus is on effects researchers' disciplines these developments. study extends an earlier cross-sectional (Vakkari et al., Journal Association for Technology, 2022a, 73, 1706–1722) by coordinated dataset representing content articles published in 31 scholarly LIS journals 1995, 2005, 2015.

Correspondence confirms existence already 1995 traces through decades. infuse concepts, research questions, approaches may also subsume vital parts own structures knowledge production.
