The material can be in the form of books, journals, technical papers, brochures, magazines, newspapers, thesis and dissertations, and in the many forms of digital media, and be found for purchase from various sources, in libraries, in broadcast media, and on internet websites. The internet has done much to make such sources of information available, but accessibility is often challenged by the volume of material available on the web. The information relating to a particular subject is not necessarily to be found in a single, centralized easily accessed location. Mature subject matter and technology is far more likely to be easily accessible, with organized, comprehensive industry websites. This is typically far less true of new and emergent technology that may be largely uncategorized and unrecognized as a discrete subject matter. 4.4.1 Case Studies This is a classic and heavily utilized reference format in the building arts. Case studies can provide significant value to the user by documenting projects in a manner that presents experience based upon completed works. The content can include various aspects of concept, building form, programmatic content, structural design, a unique building form or technology, materials and processes, and detail design. Examples of case study subject matter may include: 163
an overall architectural project, an architectural material such as glass or flooring, an architectural element or building system, such as a curtain wall or structural glass façade. or documentation of some performance aspect of a project, such as thermal, daylighting or acoustic. Many design and architecture books contain case studies relevant to the book topic. Some books are virtually all case studies, but more frequently a set of relevant case studies is presented in support of and following an expositional treatment of the subject matter. Professional journals will often include case studies, and they have become a feature of many websites, ranging from architects to professional associations and product suppliers to trade groups. 164
