Reviews of several electronic dictionaries are presented. As part of the review process, to determine how up-to-date these dictionaries are, the reviewer chose 50 words (such as artificial intelligence, backplane, digital switching, graded-index fiber, and virtual circuit) that he believed should be in a recent dictionary, even though a writing/publishing cycle could take up to 3 years. Then the dictionaries were checked against this list to arrive at a Current Factor for each.
