Cimon
2 of the 6 encyclopedias on this shelf carry an entry for Cimon. Both are reproduced below, so you can see where they agree and where they differ.
Collier's New Encyclopedia (1921)
an and statesman, was a son of the great ancient Athenian general Miltiades. He fought against the Persians in the battle of Salamis (480 b. c.), and shared with Aristides the chief command of the fleet sent to Asia to deliver the Greek colonies from the Persian yoke. The return of Aristides to Athens soon after left Cimon at the head of the whole naval force of Greece. He distinguished himself by his achievements in Thrace, having defeated the Persians by the Strymon, and made himself master of the country. He conquered the pirate-island of Scyros, subdued all the cities on the coast of Asia , Minor pursued the Persian fleet up the Eurymedon, destroyed more than 200 of their ships, and then, having landed, on the same day entirely defeated their army (469 b. c.). He employed the spoil which he had taken in the embellishment of Athens , and in 463 reduced the revolted Thasians; but the popular leaders, beginning to fear his power, charged him on his return rupted by the King of Macedon. The with having been corcharge charge was dropped, but when Cimon's policy of friendship to the Lacedæmonians ended in the latter insulting the troops sent by Athens to their aid, his opponents secured his banishment. He retired into Bœotia, and his request to be allowed to fight with the Athenians against the Lacedæmonians in 457 at Tanagra was refused by the suspicious generals. Eventually Cimon was recalled at the instance of Pericles to conclude a peace with Lacedæmon. He died shortly after, in 449, while besieging Citium in Cyprus.

What Has Changed in the Last Century
The outline Collier's gave in 1921 — Salamis, Eurymedon, Scyros, the Thasian revolt, ostracism and death at Citium — still stands, since it rests on Herodotus, Thucydides and Plutarch, and no new narrative source has appeared. Two adjustments are worth noting. Modern historians usually date the Eurymedon victory to about 466 BC rather than Collier's 469, and they argue much harder than earlier writers did over whether the 'Peace of Callias' with Persia, said to follow Cimon's last campaign, was ever a formal treaty at all. The 1900 entry is not simply wrong, either: there were two Cimons, and Cimon Coalemos, father of Miltiades the Younger, really was killed by the sons of Peisistratus, as Herodotus reports — the compiler has run the grandfather and the grandson together under one head.
