Because science is an ongoing debate, which is conducted through publications, it is sometimes important to follow that debate from a particular publication, forward or backward in time.
In Web of Science and Google Scholar you can see in which publications certain articles and books were later quoted or mentioned. In Scopus you can check that for articles. In Web of Science and Scopus, the quoting publications are always articles from peer-reviewed journals. In Web of Science and Scopus you will find not only the quoting articles (Times Cited/Cited by, forward in time), but also the articles that have been quoted (Cited References, backward in time).
If you want to look up in Web of Science in which articles a particular book has been quoted, use the Cited Reference Search option.
