Reading a book, even a chapter within a book, can be an excellent starting point when familiarizing oneself with a novel topic. Basic definitions, timelines, and major authors in a field can be assessed from a reference work, such as an encyclopedia or bibliography, while monographs can provide a much deeper understanding of key concepts, models, and arguments. Armacost Library has thousands of books in print and in electronic format, browsable by key term, title, or subject. Once you find a good book, make good use of its table on contents and/or index for best results!
