This online resource provides a readily available source that could be used by all students but especially graduate students as it contains thorough details for citations and referencing that would be necessary to complete your degree. I want to suggest that you take a look at the MHRA (for humanities) manual which is available as a downloadable pdf. MHRA Style Guide
Why MHRA and not MLA?
The MLA and MHRA are not far apart. It’s just that the MHRA offers the detailed definitive description in an easily obtainable pdf for the student/staff and removes the ambiguity of understanding how books as opposed chapters, editions, journals, magazines, articles etc are cited. This is just makes life simple.
