There is a [small difference](http://www4.caes.hku.hk/acadgrammar/general/argue/citation/subtopics/sec7refsvsbibl.htm) between a bibliography and a reference: the former includes all works consulted and the latter only those that are cited in the paper. Should we maintain this technical distinction when writing a paper?

Some journal templates require the title of the last section to be 'References'. Does this mean all the references must necessarily be cited in the paper?
