Entity is the identity of something. When a user comes to library to find the book of Macbeth, you would not know whether the user is looking for something for night reading, or the user prefers to read a French version, or just want to know more about Shakespeare,… If we can categorise all bibliographic information into different entities and record them accordingly, that would help us organise the information better to serve the needs of our users. In other words, by simply organise all catalogue into Author, Title, and Subject, is not enough.
FRBR provides us a framework to see the bibliographic universe differently. By recording and describing the different entities from the information resources, we are creating meaningful ‘information’ from information resources. We are building networks of relationships of entities that can help our users discover what they need and expand the horizon of information seeking journey.
