Use Library Catalog Search to find books available in print and online. E-books are linked from catalog records.
BTW, catalog searches also identify journals (not articles), CDs, DVDs, videos, conference proceedings, microforms, U-M dissertations and many more kinds of publications.
It is very useful to use the subjects that describe each publication in its catalog record. They will give you new search ideas and lead you to more publications on similar topics.
To expand your search, try the WorldCat to find books and other materials available at many other libraries world-wide. Books owned by U-M are identified, and it is easy to place an interlibrary loan request for the materials we don't own directly from the WorldCat record.
