Scientists who serve on high-level projects or special committees read around 21% more journal articles than those scientists who do not. Scientists who are considered high achievers by their peers read 59% more articles than their colleagues even when other variables are held constant. University scientists who have won awards for their teaching and those who have won awards for their research read roughly 26% and 33% more articles, respectively, than their cohorts. Through the 1990s, university scientists relied on libraries for over half of their readings (54%), while personal subscriptions account for 36% of their readings, and 11% of their readings came from other sources. For non-university scientists, there is less reliance on personal subscriptions (24% of their readings), but greater reliance on libraries: 19% of their readings came from their organization’s library; 23% from routed journals; 11% from Inter-Library Loan (ILL) services; 3% from academic, government or public libraries.
