Do we have (or need) a preferred way of citing a passage in The Lord of the Rings books?
Consider that the structure of this work is a little unusual. It consists of six books (plus the Appendices and the Indexes) which are grouped into three parts (The Fellowship of the Ring, The Two Towers and The Return of the King). Those three parts were originally published as separate volumes (and often still are). Many (perhaps most) people think of this as a trilogy, but in addition to being technically incorrect, this leads to confusion as the chapter numbers restart with each "book" and not each "part".
So if I want to cite the following passage:
I am glad you are here with me. Here at the end of all things, Sam.
Which of these styles is most helpful (or is there a better style)?
Book number, chapter number and name
The Lord of the Rings Book 6, Chapter 3: Mount Doom
Name of the part, and chapter name
The Return of the King: Mount Doom
In this case, adding "The Lord of the Rings" seems to be redundant, and including the chapter number is misleading as it is the number of the chapter within Part 6 and not within The Return of the King"
I generally avoid adding page numbers to the citation as there are so many editions of books that the chances of my page number matching that of whoever is reading my post seems quite small. Does this seem reasonable?
As pointed out in a comment, the question Is there a citation convention for this site is similar to this, but the answers to that question do not seem to address the unusual structure of The Lord of the Rings.
