Definition
Meaning
A digital database or website where items (books, products, services, etc.) are systematically listed and described, allowing users to search, browse, and access information remotely via the internet.

Linguistics
Semantic Notes
In everyday use, 'online catalog' is often synonymous with 'online store' or 'e-commerce site', but in academic or library contexts, it strictly refers to a discovery interface for holdings, not a retail platform. The spelling 'catalog' is primarily American, while 'catalogue' is British, though 'catalog' is common in digital/tech contexts internationally.
Dialectal Variation
British vs American Usage
Differences
Spelling: UK prefers 'online catalogue', US 'online catalog'. The UK variant is more consistent with traditional spelling, but the US variant is widely adopted in global tech terminology.
Connotations
The term is neutral in both varieties, with identical functional meaning. In UK library science, 'online catalogue' is the formal term; in US, 'online catalog' or 'OPAC' (Online Public Access Catalog) is standard.
Frequency
Slightly more frequent in American English due to the dominance of US e-commerce and tech discourse. In the UK, 'online shop' or 'website' might be used more casually for retail contexts.
