Catalogue 

A catalogue is a document containing a list of items available for purchase, typically including specifications and prices. In procurement, a catalogue may be created by a supplier in order to provide potential customers with information about the products or services they offer.

There are two main types of catalogues: electronic and paper. Electronic catalogues are often found on websites and can be browsed online. Paper catalogues are usually printed and mailed out, or distributed in physical stores.

While some businesses still rely on paper catalogues, electronic catalogues are becoming more popular as they are more efficient and easier to update. For example, an online catalogue can be quickly updated with new products or prices, while a paper catalogue would require printing and distribution of a new edition.

Electronic catalogues also allow businesses to track customer behaviour, such as which products are being viewed and for how long. This information can be used to improve the customer experience by tailoring future marketing campaigns and product offerings.
