Use the KBART template for a blank KBART spreadsheet to add your titles.
You can also download a KBART file from an existing collection if titles have been selected.
Caution: : If you wish to download the titles from a very large collection such as a HathiTrust collection or an Internet Archive collection, it will download but will truncate your titles. See Download large files for Internet Archive and HathiTrust collections and for My Selected Titles (KBART) for more information.
You are not required to fill in every column in the KBART spreadsheet. The values needed depend on the format of the collection you are creating. You have two options to enter title data.
You can add OCLC numbers to a KBART formatted spreadsheet to have the system populate some of the title data fields. Afterward, you will need to enter your coverage information and Title URLs. For instructions, see KBART values and formatting, "Autofill" values.
You can fill in the recommended title data and include your coverage information and Title URLs. For instructions and details about the data values that are required, see KBART values and formatting, Recommended values by format.
Make sure to:
Before you upload your file to the WorldShare interface, save your spreadsheet as Text (Tab delimited) (.txt).
Note: If the file includes diacritics, including non-Latin characters, save it as Unicode Text (.txt). When you upload the file in the WorldShare interface, use the File encoding drop-down list to change the default selection to UTF-16LE (Unicode Text/Excel).

Caution: Excel files (.xls) and (.xlsx) will NOT upload correctly. Your file should be saved as a (.txt) tab delimited text file, Unicode Text .txt.
Note: When reporting problems, include your Registry ID and attach the file you attempted to upload. If possible, include proxy credentials that will allow us to access full-text links. Your information is needed to diagnose and resolve certain issues.
After you upload a knowledge base collection in Collection Manager, you can check the status of your file upload by opening the Collection History accordion within the collection. Alternatively, you can view your institution's history in your institution Activity History. See Activity History for instructions and details about Activity History detailed reports.

This accordion displays a list of titles within the collection that users have selected. To find the list of title-level settings, please see Title-level settings in knowledge base collections and/or the documentation on how to Modify a collection to select your subset of titles for more information.
When viewing a global collection, use the Add a Global Title drop-down and select Create a Title to add a knowledge base title. See How to add a new title to an existing collection for more information.

When viewing a local collection, use the Add a Local Title drop-down to select how you will add a knowledge base title to your local collection. Select either Create a Title or Create Using OCLC Number to Pre-fill.

Select this option to add new titles by manually typing in the information. To add title data manually:
Select this option to have the system fill in title data automatically if the OCLC number is available. To add a title automatically:
The Auto Select Titles setting in global knowledge base collections enables functionality to automatically select titles as they are added from OCLC data updates. You can enable or disable the setting regardless of whether you have selected a collection in full or have selected a subset of titles.
The default setting depends on if you selected all or a subset of titles in a collection:
You can enable or disable the setting at any time. For example, if you have all titles in a collection selected except for a few that are regionally restricted, the setting will be disabled by default. Enable Auto Select Titles if you want newly added titles to be automatically selected. Enabling the setting will not change your current title selections. Rather, titles added in future data updates will be automatically selected.
Note: When a collection is being updated by an automated holdings feed, you should not select the option to Auto Select Titles in the Titles accordion of the collection's settings. Refer to Providers and contacts for Automatic Holdings Feeds for more information.
For more information, see Title-level settings in knowledge base collections.
Link schemes are needed in order for articles to resolve to full text. Regardless of how the collection is created (one title at a time or via file upload) you need a link scheme for e-journal collections to resolve to full-text for articles. Without a link scheme, article citations will link to the journal’s homepage instead of the article.
OCLC can create a link scheme for you, but only if:
See Link scheme values and overrides for details.
