Year of Publication

Is the information out of date?

Question to Ask Why Is It Important? Where to Find
When was the material published? For some topics, (i.e. science and medicine), you usually need the most recent information. For example, if you are researching current treatments for diabetes, you don't want a report from 1932. This information is included where you find the citation and is usually on the copyright page of a book, on the first page of an article, at the front of a periodical, or at the bottom of a Web page.
When was the Web site last updated? For some topics, you may need only current information. This information should be found on the Web site. If it is not, be extra cautious about using the information on that site.
