Few buildings have had single books written about them, so expert researchers know to conduct searches for the architect's or firm's name and across the professional and popular literature for information about a particular building.
Types of Resources
Books: Look for books when researching an architect, movement, or broad subject. Sometimes called "monographs", books can include bibliographies, footnotes, and indexes and often includes numerous images.
Arts Databases (Journal Articles): Look for articles in databases when you are researching a more contemporary/timely topic and more narrowly defined topics. Articles tend to be more closely focused on an argument, theory, or specific topic. Articles can be found in popular magazines (e.g,. AIA's Architecture) and can be peer-reviewed by experts, meaning extra vetting of information. Indexing in databases like the Avery Index allows simultaneous searching by subject across hundreds or thousands of magazines and journals.
Newspaper Articles: Published quickly and frequently, often documenting a particular place, easy to read
Biographical Information: Quickly look up an architect's nationality, birth and death dates, titles of major works, writings, etc.
Primary Sources: Present first-hand accounts and direct evidence, as in correspondence, diaries, or photographs
Dissertations and Theses: Find out which topics current and past scholars have researched extensively, look at their bibliographies for additional sources
Image and Video: Documentary visual evidence
