The Web of Science is a truly multidisciplinary(多学科,综合性) database of over 8,600 journals in 200 categories(领 域). This allows you to discover obscure relationships between disciplines and get the complete picture of any particular research topic. It also gives you a broad and even insight into the entire academic publishing community. This is absolutely essential for performing non-biased and systematic research evaluation using bibliometrics(文献统计学).
We are not associated with any primary publishers of academic journals. Our selection process is unbiased and impartial. We evaluate all types of journals including journals from commercial publishers, academic society journals, open access journals and electronic only journals.
