* Work is defined as the intellectual or artistic content of a distinct creation. It refers to a very abstract idea of a creation e.g. Shakespeare’s Romeo and Juliet and not a specific expression.
* Expression is the intellectual or artistic realization of a work. The realization may take the form of text, sound, image, object, movement, etc., or any combination of such forms.
* Manifestation is the embodiment of an expression of a work. For example a particular edition of a book or a specific music recording.
* Item is a single exemplar of a manifestation. Cataloguing is generally done, based on an item directly available to a cataloguer
