Amiga System Libraries Overview

This table lists the system libraries, devices and resources, along with a brief description of their function and version information. Full details of the use of the libraries can be found in the Amiga Reference manuals.

Points to note:

• Many libraries are commonly used on systems that initially didn't ship with them, e.g. GadTools is available for OS 1.x systems.
• Some libraries (e.g. exec.library) were part of the OS earlier than V33 (1.2), but 1.2 is considered as the first widely released version and is thus listed as the introduction date.
