When you have an assignment that requires you to consult sources other than those assigned by your instructor, you may be overwhelmed about where—and how—to begin. After all, Harvard has more than 28 libraries containing more than 20 million books, 400 million rare items (manuscripts, letters, photographs), and six million other digitized items. Harvard also subscribes to about 1500 databases.
In this section of the Harvard Guide to Using Sources, you will find information about how to use the Harvard Libraries to locate sources that are appropriate and useful for your assignment, how to evaluate the sources you find, and how to integrate the information and ideas from those sources into your own written work.
