Record display information

MARC fields

The MARC records returned from this database will be the OCLC-MARC records as they were input into the system.

This database can have any valid MARC tag in it. Besides the valid MARC tags, the following FirstSearch Locally Defined fields also exist:

856 fields

OCLC has added links to additional content such as cover art, table of contents, summaries and author notes. These OCLC-created 856 fields include the following subfields:

856/u URL to additional content

856/i instructions in URL use

856/q data type such as "ASCII," "GIF," etc.

856/x "OCLC EC"

856/3 type of content such as "COVER ART," "TABLE OF CONTENTS," "MORE INFO," or "EXCERPTS"

Evaluative content info in websites: OCLC created URLs contained in 856/u fields in full MARC syntax and under the label "Access:" in full SUTRS syntax will allow internet-based access to evaluative content (cover art, summaries, excerpts, author information, etc.) These URLs can be cut and pasted, or programmatically entered, into any browser supported by FirstSearch in order to gain access to the information. The URLs will time out after 7 days so if continued access is desired another search to receive and updated URL will need to be executed. The 856/i field is the indicator for information on the URL; because not all 856/u fields are additional evaluative content, the 856/i should be checked to be certain the 856/u link is truly a OCLC sourced link. The 856/i field contains instructions regarding the URL.

NetLibrary websites: All NetLibrary records have had additional 856 fields added that would authenticate a user's access to their library's NetLibrary book subscription, based on their FirstSearch authorization number. These 856 fields will have a subfield u with the URL and a subfield I with the instructions:

"Input this URL in a browser to view e-book from NetLibrary".

Note: Searching "NetLibrary" in the Access Method index can retrieve all NetLibrary books. All NetLibrary books that a FS user subscribes to can be searched by ANDing this to the library's holding symbol, assuming the library is cataloging their holdings on the OCLC WorldCat cataloging subsystem.

Searching tips

Keyword All searches (1016): The Keyword All search includes elements from the Abstract, Author, Title, Subject, Source Phrase, and Note indexes.

Using restrictors: English and Non-English are restrictors. All other language terms can be searched alone in the Language (54) index.

Using limiters: Use the Document Type (1001) index to limit an index search in order to narrow the focus of your search. OCLC uses this index as a limiter on the web.
