What is different between major and minor prophets?

The distinction between major prophet and minor prophet with respect to the Old Testament and Hebrew scripture is not necessarily intuitive. The minor prophets refer to a collection of writing of 12 prophets in a single book in the Hebrew scripture but broken into separate books in the Christian Old Testament (Hoseato Malachi). Major Prophet describes the longer books of prophecies in The Bible whose name matches the prophet it describes namely Isaiah, Jeremiah, Ezekiel, and Daniel.

Elijah and Elisha would be considered in the top ten of prophets yet they are not "Major" prophets because their record is found in books of 1 and 2 Kings rather than in the prophetic writings. So the terms "major" and "minor" in this context refers to two groups of books and does not signify their importance.
