Reference management tools let you keep track of your citations and pdfs, collect articles and data, share references, format bibliographies and add footnotes to your papers.
Citation counts measure the impact of a publication, an author or a topic, by counting the number of times it is cited by other works. No Single citation analysis source covers all publications and their cited references.
The major citation count resources:
-- Google Scholar does not index all scholarly articles.
-- Author names can be tricky to search and results can vary depending on how the name is entered.
-- Variants in how the item is cited can result in more than one entry for the item under study.
-- The term "citation" in brackets [CITATION] at an entry, indicates that full text is not accessible through Google Scholar.
Other indexes: Proquest, BioOne abstracts and more.
