4. Upload files in My Files

You can upload your files using My Files, which is located under the Metadata module in the WorldShare interface. You also have SFTP options.

 Note: 

• For bibliographic and delete WorldCat holdings collections, you can submit MARC, MARCXML, BIBFRAME 2.2.0 and ONIX 3.0 or above files for data sync processing.
• When uploading using My Files, please note that there is a one (1) gigabyte file size limit. If you have files to upload that exceed the 1 GB size limit, please upload using SFTP.
• Uploaded files are retained in the WorldShare interface for one year. To verify that your files have been processed, click Uploads and search for the collection ID and date the file was uploaded in the File Name column.

• OCLC institution symbol - Include as the second element of the file name, separated from the collection ID by a period.
