About our site
Upgraded to taxonomy-driven logic for category searches in December 2005
Philosophy: users first, advertisers second
Currently maintaining aggressive release schedule
Business name search also utilizes alias tables
Our taxonomy: properties
Product + service taxonomy Housed within a proprietary application
inherited from our parent company (UK) Hierarchical structure with categories
represented at the highest level Search categories are aligned with print
headings and maintained accordingly Maintained and developed by team of
information scientists
