title: [Heterogeneity in bibliographic references].
abstract: Bibliography plays an important role in the writing of books and papers, as it permits us an exchange of experience, the reading of case reports, the revision of articles and new investigative aspects. Bibliographic references in the same chapter of six books from different countries, published in the same period, were analyzed, and a strong heterogeneity was found among them. The "language pattern" varied depending on the author's native language. The temporal distribution of articles was also different and only a small percentage of articles was common to two or more books. Our results showed that the same chapter in different books have highly heterogenous bibliographic references, although they should have similar contents.
