There are zillions of citation styles to reference publications, especially in academic writing. Browsing late 19th century journals I was suprised by the lack of formal bibliographies and references, as usual today. When and how were they introduced in scientific publications? Is there a history of citation styles?
Im am not interested in the evolution of particular citation styles but in the evolution of the idea of formal references in scientific publications. It looks like until the 19th century it was common to just refer to "the recent results" instead of citing a list of specific articles with author, title, journal, pages etc. Citation styles are usual no later than the 1960s, the introduction of citation analysis by Eugene Garfield may also have had an impact. I guess that formal citations got obligatory during the early 20th century, but when and how?
