Summary
This is a survey article intended as an elementary introduction to the general index locality principle introduced in [17]. We discuss it and give some examples of its consequences and applications showing that this principle often proves to be a powerful tool for obtaining index formulas in various situations. Proofs can be found elsewhere; we provide only references. A lack of reference usually means that more detailed explanations can be found in [17]. A detailed account of the history of the problem is contained in [17]. We start by recalling elementary notions of elliptic theory.
