You add tags and subfields to a MARC record when you want to add information to that record. If you add a tag or subfield that is not already defined by your system administrator, the MARC Editor lets you put it in, but marks it as an error. If you have activated Error Checking, the error displays with the font or color settings determined in the Customize Editor. (For more information, see Activating Error Checking in Records.) You can add non-linking and linking tags and subfields.
When you have your insertion pointer in a component marker (such as a tag, indicator, or subfield delimiter) or in any other component that has valid values defined, you can press F12 for a list of valid codes. Double‑clicking on the code that you want inserts it into the proper position. (Horizon notifies you if no valid codes are available.)
