The Business Directories category only lists business directories which span more than a single continent and cover multiple business industries. Excluded from this category are:
- Industry-specific directories are listed according to the industry which they cover. For example, a directory of hospitality industry businesses would be listed in Business: Hospitality: Directories.
- Regionally-specific business directories (local, state/province, or national) are listed according to the geographic area which they cover. For example, a state business directory would be listed in the category for the state it serves.
