To ma an institutional repository is a *component* of the digital 
library.  A digital library might consist of an repository where digital 
objects are persisted, preserved, and managed but it also needs a 
presentation layer, tools for collection building, metadata creation, 
discovery tools, and scanning/transformation services of objects which 
are not born digital, etc.

Typically I've seen digital libraries start by identifying a collection 
based on a genre, material collected and stored in a "digital library in 
a box" (like DSpace or Greenstone) and then made available through the 
UI provided by the all-in-one solutions.

I am working on a model which collects and persists all of the available 
digital objects and persists them to a repository, then collections can 
be built from any of the material in the repository as well as material 
from other institutional repositories.
