Bibliographies
Introduction
All rigorous writing must supply evidence to support the presented arguments and to place the arguments in context. This entails citing appropriate elements of the existing literature - which might include printed books, articles or papers, hand-written manuscripts, and, increasingly, electronic sources such as URLs and DOIs. The citations are usually collected together and given at the end of the work in a separate section, entitled References. In the past, citations were often presented as footnotes to the main body of text, but this practice has now largely died out, at least in scientific or technical works.
