Measuring the impact of piracy and open access on the academic library services
MULLER, Floriane Sophie, IRIARTE, Pablo
Abstract
The University of Geneva library has seen, like others around the world, a slight but steady decrease in its document delivery service usage for a few years now and this decline also seems to affect the use of the electronic licensed collection. Indeed, 2016 was the first year where usage of licensed journals decreased. How could it be correlated with other actual trends, such as an ever growing open access corpus and an increased visibility of shadow libraries like Sci-Hub? To what resources and services, beside the offer of the library, can our scholars turn when they need an article? In this work we try to reveal and understand the mechanisms that operate behind this gradual disengagement of scholars in our library services. Working a reverse way, we checked in WoS all the papers published in 2015 and 2016 by authors affiliated in Geneva University STM faculties (3'833 and 3'989 articles respectively). Then we extracted all the references cited in those papers (364'445 references, 80% having DOIs) and enriched them with more identifiers, bibliographic data and access information, using bibliographic APIs from CrossRef, [...]
