Classificaiton
Class inclusion relationship between
Instance
Class

For a purpose
Conceptual roadmap
Helps navigate
Add structure

Systematic
Logical arrangement
Not physical
Tagging
Social classificaiton
Less systematic
Un-controlled vocabulary

Flexible
Efficient
Not possible in physical organisation
All facets are independent

Often limited
Also called hospitality
Create more 'logical space'
Room for new classifications
e.g. Numbers
