Find the data requirements for a bibliographic data sync collection in WorldShare Collection Manager Fundamentals.
Note: If you are a WMS library or using full WorldShare Collection Manager, please see 3. Data requirements for bibliographic collections.
Data synchronization allows for the processing of multiple file formats. In order to ensure your files are processed correctly, please follow the data requirements below.
Note: MARC data is required for all bibliographic collections.
Leader and Directory
MARC records must contain valid Leader and Directory information in order for a file to be recognized and processed correctly. Please consult the Library of Congress MARC 21 Format for Bibliographic Data for valid Leader and Directory information.

Please ensure that your submitted UTF-8 MARC data files do not begin with a byte order mark (BOM). MARC data files received with byte order marks will be rejected.
- A byte order mark (BOM) is a sequence of bytes embedded in some Unicode files to help make sure they are read correctly by some web browsers and server environments. The Unicode Standard permits the BOM in UTF-8 (hexadecimal values EF BB BF) but does not require or recommend its use. Byte order has no meaning in UTF-8 and OCLC does not accept UTF-8 encoded files containing BOMS.
Fields and subfields
MARC records must contain valid field and subfield information in order for a file to be recognized and processed correctly. Please consult the Library of Congress MARC 21 Format for Bibliographic Data for valid Field and subfield information.

-
Field/Subfield |
Field/Subfield name |
Requirement |
035 |
System Control Number |
Required if available. If available, include an OCLC control number, with valid prefix, in every record. |
040 b |
Cataloging Source: Language of cataloging |
Include a language code if any cataloging data is in a language other than English. If this is not coded, our system will assume the item is cataloged in English. |
040 e |
Cataloging Source: Description conventions |
Include a cataloging description MARC code for rare and archival materials only. |

Character Sets Present |
Where this field exists, include 880 fields. |

**Use UTF-8 Unicode or MARC-8 character encoding.
Caution: For all tags, but especially when entering text into text fields (e.g., Comment, Description, etc.):
- Do not add new lines. All text needs to be in one paragraph.
- Do not copy and paste text from Microsoft Word, email, a web browser, or other sources. Pasted text can contain hidden formatting codes which can generate errors.
- Tag order
- Fields 001, 003, 005, and 035 should be in tag order.
- Duplicate records
- Each record sent for a single symbol should have a unique local system number in a consistent location. Although this list is not exhaustive, local system numbers are typically found in the following tags: 001, 049, 035, 9xx, and 852.
Caution: When the system identifies duplicate records or multiple matches in your submitted data sync file, the file will be rerun in an attempt to resolve the issue. Multiple reports and files may be generated for each retry.
