Chronologies are useful to contextualize research in time, highlighting links to other events. They include a list of major events in chronological order.
- Hellemans, Alexander - Bunch, Bryan, The timetables of science : a cronology of the most important events in the history of science (New York, Simon e Schuster, 1988)
- Cronologia universale : dalla preistoria all'età contemporanea (Milano, Garzanti, 1994).
