VisualBib is a Web application which enables users to build, enrich, share and analyze scientific bibliographies. It allows the realtime query of bibliographic indexes such as Scopus, CrossRef, Orcid and OpenCitations in order to retrieve metadata about papers and authors. The application is based on the zz-structure model for data representation and navigation and uses particular zz-views, called narrative-views and deep-views to visually represent bibliographies. The last 3.0 version of application (Oct. '19) allows to display, in addition to the collaboration and citation networks, the subject areas attributions, the authors and system keywords and the semantic tagging of the papers. The current version is also enriched with a control analysis section and a bibliographic analysis environment. The first permits to explore the list of papers, authors, subject areas, keywords, tags and paper types, to apply various sorting criteria, to analyze the co-occurrences of specific items, to select subset of papers according to different criteria in order to tag or analyze them. The bibliographic analysis environment includes two radar charts which present a series of metrics for papers and authors and enables comparative and aggregate analysis.
