For registered students on this Newcastle University course, all the readings are available through the Newcastle University library website:

MUS2065 - Reading list

To see a reading simply click the blue arrow on the right of it and if it is an electronically available article it will take you directly to it. If however, it is a book, or an article that is only held in physical form, you will be directed to the library holdings. This does mean that you have to actually go to the library to read it (in some cases, key texts can be reserved to read if it's in the student texts collection).

If you are not registered but want to join in the discussions, you'll find summaries of selected readings for each week at the ispopmus blog

For registered students:
JSTOR: Electronic access through our library gives you access to the complete back list of key journals in our subject such as Folklore, American Folklore, Ethnomusicology, Popular Music, British Journal of Ethnomusicology, Yearbook for Traditional Music etc.

The Folk Music Journal, in its various forms is all catalogued on JSTOR, but there is no full text access—this is in the library if you want any particular articles.

A very good place to start is always the Grove Dictionary available through the University with full text at http://www.oxfordmusiconline.com.*

Google Scholar is very useful for searching articles and particularly when you use “double inverted commas” or quotation marks to specify an entire phrase to search. For example searching “traditional music” will give much better results than searching ‘traditional music’ as two separate words in the search box. You can also combine this for even better results such as: ‘supernatural AND “Scottish Ballads”.

Google Books is also useful for full text books depending on various copyrights and permissions etc. There are also one or two websites that give full text of out-of-copyright books (e.g. www.archive.org).
