1. Certain codes must be used in the same way by all libraries for suppression of bibliographic records. Local sites should use the labels below for suppression codes for their internal code lists (DB Prep minutes: 8-2-91, 6-5-92).
| BCODE3 | Bibliographic records | |
| ICODE2 | Item records | |
| CODE4 | Order records | |
| SCODE2 | Checkin records | |
| Code | Meaning | Label |
| blank | Display in both local and central OPAC | DIS LOCandCENT |
| Z | Display in the local OPAC, do not contribute to central | DISLOC/NOCENT |
| S | Do not display in local OPAC, do not contribute to central | SUPLOC/NOCENT |
| r | Do not display in local OPAC, contribute and display in central | SUP LOC/DIS CENT |
| g (Bcode 3 only) | Display local, Display at central with text "OhioLINK resource" | DIS LOC/OL RES |
| o (Bcode 3 only) | Suppress local display, Display at central with text "OhioLINK resource" | SUPLOC/OL RES |
Use of code "L--Display in local OPAC, contribute but do not display in central OPAC," and code "N--Do not display in local or central OPAC, contribute to both," is being phased out. They should not be added to new records.
