Libraries are still the best place to find primary and scholarly sources, an essential element in any research project. And if a library does not have its own copy of a source, it can borrow resources from other libraries through interlibrary loan. Libraries are staffed with librarians who are often subject matter experts or at least knowledgeable about their own collections. Getting a librarian's assistance can mean having access to resources you never would have known about. And library collections are heavily vetted. Students can be sure that the majority of items in a library are reliable sources.
