Cataloguing is the organisation of information

If you ask librarians ‘What is cataloguing?’, very often you will get a reply like ‘Cataloguing is the organisation of information’.

The statement is true. In fact, we should say ‘Cataloguing is the organisation of information resources’. We are organising the resources (the things, the books, the physical objects) by their common characteristics.

We organise by the subject matters of the resources.

We organise by the creators, or the authors of the resources etc.
