If a MARC bib is imported from another source (such as OCLC, Library of Congress, NLM, or MARCIVE), those data are applied to the batch file where it may be more fully processed and tuned for the catalog.

Conversely, if the MARC bib is in the catalog and it needs adjustments, then a batch may be created, and the bib added to the batch. The changes made in the batch are not applied to the catalog until the Update occurs.

Similarly, original cataloging takes place by creating a batch, and then creating a new MARC bib within the new batch. The Update applies the new bib to the catalog.

The format of this window implies the processing order. First, a batch is selected. Typically, this selection may be made by a preceding step of Importing a MARC bib file (see the discussed above). Once the batch is determined, then the cataloger will typically work down the first column of functions, and then down the second column of functions. Not all of the functions need to be run. During this process, the Batch Control will look for some obvious simple problems ( e.g., multiple call numbers, MARCout conditions, etc.) and display associated error messages near the top of window until the problems are remedied.

Only applicable functions will be selectable. For example, until the batch is processed through function [Update Batch to Catalog], function [Item Creation] cannot be run. Conversely, once function [Update Batch to Catalog] is run, then it cannot be run again (without changing the batch's status) nor can [Create a New Bib], [Add or Copy Existing Bibs], or [Edit Bib Functions] be used.
