The impact of broad scope arises more from the heterogeneity of the resources and users in a collection rather than from their absolute number.
Larger collections need more people to organize and maintain them, creating communication and coordination problems that grow much faster than the collection.
The best way to prevent problems of scope and scale is through standardization.
