Citation searches: backward chaining
Many publications, both online and on paper, contain a reading list (or: bibliography) at the back. This is a list compiled by the author of the literature consulted or of suggestions for further reading on the subject. This can lead to finding other useful books or articles.
When using an article from a database, it is often possible to click the link to the publication referred to in the article’s bibliography. When doing this, you are always searching back in time, because the literature you find in the bibliography of a publication is always older than the publication itself.
Example:
In this article from Business Source Premier on Global Consumer Innovativeness and under the heading Cited References, you will find 76 references to literature cited by the author.
