There is a research guide on the Alumni Library home page for Civil Engineering that can show you places to look for books and articles. Look under "Research by Subject" to find the guide.
First, try to come up with a list of keyword search terms such as "civil engineering", "sustainable", "construction", "sustainability", "building", etc. and use them in varying combinations. Search the Library catalog for books and e-books; search the databases suggested on the research guide for articles.
