Wikipedia is cited in high-profile scientific journals, despite its poor reputation as information source. What warrants this acceptance by scientists? In search for answers, this article presents an assessment of the English Wikipedia according to Silberger's guide for reference works, analyzing its purpose, scope, arrangement, information given, access, and special characteristics, with an additional aspect: quality control of new content. An account of the author's experience in creating an entry in the Portuguese Wikipedia complements the assessment. In conclusion, Wikipedia has high quality content, with advantages such as the large volume of content in many languages, as well as disadvantages such as the emphasis on “popular” topics. There is also inadequate content, whose containment and repair depend on the literacy and engagement of the linguistic community that publishes it, as well as on following Wikipedia's editorial principles. Content creation is an opportunity to engage higher education students, as well as content evaluation, which is a form of peer review. Fruitful use of Wikipedia content depends essentially on the reader's critical judgment.
