For instance, complex algorithm implementations (graph, sort, etc.), the proposition of complexe data structures (tree), the interface with external hardware or network resources, etc. All these issues are candidates to be libraries.

A framework can use multiple libraries to define its ... A library can reference another library, but to a lesser extent compared to frameworks
