Introduction
Mendeley: one of the most important altmetric toolsFor publications in Mendeley readerships statistics are available‘Type of users’ of the Mendeley readerships are available for readerships & publicationsPossibility of different types of impactReadership habits across types of usersBut, with the limitation: Mendeley only reports the 3 ‘top’ frequent types of users per publicationSlide3
Research questions
What are the differences in readership activity across research fields?In which fields are Mendeley users most and least active?What are the fields of interest for the different ‘known’ users?Are there differences?Slide4
Methodology
All 2011 WoS articles & reviews with a DOI1,114,776 publications (citations counted up to 2013)Readerships statistics collected through the REST API847,587 (76%) saved in Mendeley438,399 (52%) all the readers were knownVOS viewer for overlay visualizations250 JCR subject categoriesTerms from titles & abstractsSlide5
Readerships by subject category
Readerships/publicationReaderships/CitationAreas with higher readerships per publication:Cell biologyBiomedical sciencesMultidiscisciplinaryNeurosciencesBusiness & managementReadership activity vs. citation activity:
Social SciencesHumanitiesSlide6
Social sciences & humanities
Lit. & pol. scienceCognitive psychology
Marketing & innovationGeneral medicine topicsSlide7
Readerships: PhDs vs. Professors
Only papers with known users (52%)PhDs:ChemistryEngineering(PhDs/all PhDs)(Readerships/all readerships)Professors:Mathematics, appliedPolitical scienceStatistics & probability
(Prof./all Profs.)(Readerships/all readerships)Slide8
Conclusions
Mendeley: rich source of altmetric informationDisciplinary differences in readership activity: biomedical sciences, life sciences and social sciencesDifferences among ‘Mendeley’ users across disciplinesFuture research: understand better these differencesData problems, distribution of users by fields, genuine content differences, etc.Slide9
