The Library provides access to E-book collections. See two sample searches below, which I embedded within this guide.
To refine your search, use filters as well.
Materials on Ethnomusicology are generally found in the ML section at the library, classified as 'Literature on Music'. While a specific area within ML is set aside for works on ethnomusicology (ML 3797.6 - 3797.9), especially general works on theory, or introductory texts, much of the specific stuff is found in other areas of ML. For example the book, Music of the First Nations is found in ML 3557.
