# Record Reference Documentation The documentation below for the record types and menus included with Base was converted from the old EPICS Wiki pages and updated. This list only includes the record types supplied with Base.

The document sources can be found in the `src/std/rec` and `src/ioc/db` directories in files with extension `.dbd.pod`. The documentation source format is a combination of the EPICS DBD file format with an extended version of Perl's POD (plain old documentation); run `perldoc pod` for details of POD.
