A catalogue is a systematic list or collection of items, often organized in a specific order. It can include various types of information, such as books, products, or artworks. Catalogues are commonly used in libraries, stores, and museums to help users find and access items easily. In a library, for example, a catalogue may provide details about each book, including the title, author, and publication date. Similarly, a product catalogue in a store showcases available items, often with descriptions and prices, allowing customers to make informed purchasing decisions.
