Scope: Minimal-level cataloging (MLC) is an abbreviated form of cataloging that gives limited bibliographic description, subject analysis and (in most cases) authority work. Materials eligible for MLC include low-need and/or low research value titles.

Any record input by LTS should be described according to RDA. If the record is based on AACR2 copy input as MLC (Encoding level not blank) by LC, it is acceptable to leave the record as AACR2. Modify the in-process record in Voyager to OCLC to bring it up to the LTS minimal level standard, as defined below.

MARC 21 Definition | Tag | LTS Minimal Level Requirement |
Library of Congress Control No. | 010 | Mandatory if applicable. Enter any DLC label mounted on the cover. |

System Control Number | 035 | Retain the OCLC control number if present. Do not include an OCLC control number for a different manifestation. Do not include an OCLC control number for a non-English record (that is, 040 |b must be blank or “eng”). |

Access points should be consistent with the structure of the Voyager catalog. NoteLC Name Authority File. Note: it is not necessary for every MLC access point to be represented by an authority record in the national file.
...
- If you find an authority record, use that form, which is the authorized access point, and control the heading.
- If you don't find an authority record, search Voyager FOLIO (the public catalog search may be more effective) and use a form from a Voyager an existing bibliographic record. If several forms of the name or uniform title occur in Voyager, select a heading form in this order of preference: a full RDA or AACR2 record; another MLC minimal level record; an LC in-process (Encoding level 5) record. Use judgment to select one of them; make a quick decision in most cases.
- If the heading is new to Voyagerus, do a quick search of OCLC. If a form is found in other bibliographic records, use that form. Otherwise, formulate the heading using RDA, information from the item, and information you've discovered by searching Voyager.
- If the heading conflicts with a heading that already occurs in Voyagerour catalog, resolve the conflict by making additions to the MLC heading in your record.
- If the conflict cannot be resolved in this manner, create an RDA NACO authority record.
Note, the only instance in which you would make a NACO authority record is when the chosen access point conflicts with an access point that is already in Voyager our catalog and you cannot resolve the conflict without further research.
2. Titles (130, 240). If the item is a translation and the original title is known, supply the preferred title for the original + |l Language. Follow the procedure in (1) above to find the preferred title or name/title combination. Remember that RDA requires what we used to call “uniform titles” in two more situations:
- If the work is a complete compilation with one creator, RDA requires a conventional collective such as “Works. |k Selections” or “Short stories. |k Selections.” NB: As of August 2013, CUL does not follow this rule. See Chart #2.title.
- If the work is a compilation with more than one creator, you may need to devise a 130 if the title proper is in conflict with another title in the database.
- Supply these titles if the choice is easy and quick. You should check for an authority record for any name/title 100/240, but you do not need to create NARs in these situations.

Starting on December 1, 2014, LTS exclusively uses FAST subject headings on minimal level records. This change applies to minimal level (that is, encoding level 7) cataloging only and not to class-on-receipt (encoding level 3) or full cataloging.
Consult LTS Procedure #127, FAST Headings for Cataloging for guidance on the use of FAST.
