We separate our full text urls from our “supplementary” URLs for such things as tables of content, etc.

• Our MARC records use 956 fields for full text urls. These 956s are from a record service called MARCit, and they are all for full-text e-journals. So, regardless of indicators, the presence of a 956 means it is an e-resource. Some records that have a 956 are records for a print journal. A 956 was added to it to provide access to the e-version. So, it is a single record that provides access to both the print version and the e-version. Other records that have a 956 are specifically for the electronic version.
• The contents of subfield u in an 856 or 956 field will be a URL.
• A single bib record may have both a “table of contents” or “supplemental” URL in an 856 and a full-text URL in an 856.

Note: there may be more than one fulltext URL in a single bib record.

Algorithm:

1. any 956 field, regardless of indicators
2. 856 field if second indicator of “0”
3. 856 field if second indicator is NOT “0” or “2” AND subfield z and subfield 3 do NOT contain “table of contents”

Note: there may be more than one supplementary URL in a single bib record.

Algorithm:

1. 856 field if second indicator is a 2
2. 856 field if second indicator is NOT “0” or “2” AND subfield z and subfield 3 contains “table of contents”
