The Coq library is structured into three parts:
- 
The initial library:
-  it contains
 elementary logical notions and datatypes. It constitutes the
 basic state of the system directly available when running
 Coq;
 
 
- The standard library:
-  general-purpose libraries containing
 various developments of Coq axiomatizations about sets, lists,
 sorting, arithmetic, etc. This library comes with the system and its
 modules are directly accessible through the Requirecommand
 (see 5.4.3);
 
 
- User contributions:
-  Other specification and proof developments
 coming from the Coq users' community. These libraries are no
 longer distributed with the system. They are available by anonymous
 FTP (see section 3.3).
This chapter briefly reviews these libraries.
