856 and 956 URLs

The Central Catalog contains records from the OhioLINK Office Catalog with 856 links to consortially purchased and leased e-resources in addition to approved OA material.

OhioLINK uses two MARC fields for URLs of electronic resources (e-resources) in member-contributed records to the Central Catalog:

  • 856 — for specific open access e-resource records (government documents or websites, electronic theses/dissertations, or items held in a local institutional repository)
  • 956 — for links to supplemental resources

For more information, see the Links in Member-Contributed Records in the Central Catalog Policy (December 2022). Instructions for implementing the change will be provided in the InfoHub for anyone who needs them and once they are available they will be linked to from here.

Field Use for Example
  1. Government documents or websites
  2. Electronic theses/dissertations (ETDs)
  3. Items held in local institution repository

More information about contributing open access e-resource records to Central is available on Ostaff

Setting up the 956 field in your local catalog

Most libraries should already have the 956 field in use. Below is information on setting up the field.
