Socrates did not write anything himself. We know of his views primarily through Plato’s dialogues where Socrates is the primary character. Socrates is also known through plays of Aristophanes and the historical writings of Xenophon. In many of Plato’s dialogues it is difficult to determine when Socrates’ views are being represented and when the character of Socrates is used as a mouthpiece for Plato’s views.
