Refers to a collection of materials that are typically segregated from a general library collection according to form, subject, source, value, etc.  Although the Learn & Work Ecosystem Library is itself a specialized collection of information resources pertinent to the learn-and-work ecosystem, smaller subsets of information (sub-collections) are also available at the Library to serve particularized information interests of stakeholder groups; for example, alliances of organizations interested in resources on a particular topic such as Learning and Employment Records (LERs). The Library includes these sub-collections in its Special Projects section.
