Abstract
A previous study conducted through a survey of academic libraries at 100 US universities with the highest total expenditures on academic libraries according to data presented by the National Center for Education Statistics (NCES). The results pointed out an unexpectedly weak correlation among web variables, concluding that the complex online structure of US academic libraries was the main driver of this effect. The present study replicates this research applying the same web indicators but at the university level, to check whether the weak compactness among web indicators persists. Additionally, the percentage (in terms of web data) of academic libraries at universities is analyzed. Finally, the correlation among web and economic indicators (research expenditures, student population, and reputational rank position) for universities is calculated to check for a possible relationship. Results confirm a strong correlation among university web indicators. Otherwise, the strength of academic libraries at universities is moderate in terms of page count, but weak in terms of visits. Finally, the correlation among university web indicators and research expenditures depends on student population.
