Unless you know the title and/or author of the book you are looking for, research topics should be searched by Keyword to maximize the number of references to a topic. A keyword search for "Beatles" yields over 50 search results.
However, another way to search is to browse by Subject. This strategy is especially useful if you are having trouble narrowing your topic.
Books about topics pertaining to The Beatles themselves can be found in the ML section of the library. You may wish to examine other books that deal with rock music. These are also classified as ML.
Since The Beatles' influence was not confined to music, and since they became an international cultural phenomenon, you will find books in many sections of the library that are potentially useful for your research project.
