LibraryMate allows users to specify the categories of items in their library. The window below provides
an explanation of how to build a catalog structure. A maximum of 1,000 categories can be added. Each
category is assigned a 3 or 4 letter code and a 3 digit number. The 3 digit number becomes the first 3
digits of every identification number in a category. A maximum of 1,000 items can be added per category.
