About the repeating catalog merge area
When you select Catalog Merge as the merge type in the Mail and Catalog Merge task pane, a catalog merge area appears on the publication page. The catalog merge area is the rectangular region of the page in a catalog merge template where you insert merge fields as placeholders for the information in your data source. When you complete the merge, the information from your data source will populate these fields, and the contents of the catalog merge area will repeat in the merged publication pages until all of the records from your data source are displayed.
You can change the way the catalog merge area repeats on the page in your merged publication by resizing or moving this area in your catalog merge template. If you move your mouse pointer over the area, a ToolTip displays the number of times that the catalog merge area will repeat per page.
If you make the catalog merge area larger, you will decrease the number of records that appear per page in your final merged publication pages. If the catalog merge area is large enough, it may only appear once per page. If you make the catalog merge area smaller, you will increase the number of records that appear per page in your merged publication pages.
When resizing the catalog merge area, think about both the amount of information in the records in your data source and the page size of your merged publication pages. Make sure that the catalog merge area is large enough to display this information clearly.
