For a more realistic view of citation frequencies, this slide shows that from 1900-2005, about one half of one percent of cited papers were cited over 200 times. Out of about 38 million source items about half were not cited at all. Keep in mind that “items” includes not only substantive articles but also ephemera mentioned earlier. Therefore, these data provide a distorted picture for high impact journals where the number of uncited publications is much smaller.
