  We review experimental results, from transport to magnetization measurements,
on different graphite samples, from bulk oriented graphite, thin graphite films
to transmission electron microscope lamellae, that indicate the existence of
granular superconductivity at temperatures above 100 K. The accumulated
evidence speaks for a localization of the superconducting phase(s) at certain
interfaces embedded in semiconducting crystalline regions with Bernal stacking
order.
