This file is probably the single most important element in the SBIS system. Individual records will describe documents that may describe Technologies, Methods & Tools, Policies & Programs, R&D Projects, Buildings, or other items of interest. One of the main sources of records will be conferences related to sustainable building. These are considered to be especially suitable because they have been screened for quality in addition to being appropriate in subject area. As with other files, records can be browsed or searched according to a variety of criteria.
