According to the MHRA Style Guide, this item should be cited in a bibliography as follows:

Hahn, Hans-Joachim, ‘Germany’s Identity Problems as Reflected in Nineteenth-Century Literature’, in MHRA Working Papers in the Humanities, 2 (2007), 30–48 <https://www.mhra.org.uk/publications/wph-2> [accessed 7 December 2023]

This is how standard MHRA style would look. Some of its book series (notably Legenda) allow an alternative citation system called 'author-date', but please talk to your editor before using it. (To see the demonstration for author-date, follow this link.)

Let's take this bibliography entry one step at a time:

Step 1. We start with the name(s) of the author(s) of the article, inverting the first name into the form 'Forename, Surname'.

Hahn, Hans-Joachim

Step 2. This is regular MHRA style, so the name's followed by a comma.

Hahn, Hans-Joachim,

Step 3. Now we add the title, in single inverted commas. Any single quotation marks already in the title must be converted to doubles.

Hahn, Hans-Joachim, ‘Germany’s Identity Problems as Reflected in Nineteenth-Century Literature’

Step 4. We have to say where this comes from, so:

Hahn, Hans-Joachim, ‘Germany’s Identity Problems as Reflected in Nineteenth-Century Literature’, in

Step 5. Next we identify where the article is to be found, using italics, not quotation marks, for the volume title.

Hahn, Hans-Joachim, ‘Germany’s Identity Problems as Reflected in Nineteenth-Century Literature’, in MHRA Working Papers in the Humanities, 2

Step 6. Since this is a journal, no need for place of publication or publisher, only the year.

Hahn, Hans-Joachim, ‘Germany’s Identity Problems as Reflected in Nineteenth-Century Literature’, in MHRA Working Papers in the Humanities, 2 (2007)

Step 7. Now the pagination. This is a journal, so we don't use 'p.' or 'pp.'. Number ranges are elided in the last two digits: thus '2234-2265' should be '2234-65', and '102-109' should be '102-09'.

Hahn, Hans-Joachim, ‘Germany’s Identity Problems as Reflected in Nineteenth-Century Literature’, in MHRA Working Papers in the Humanities, 2 (2007), 30–48

Step 8. This is an electronic publication, so we give the URL. Note the angle brackets!

Hahn, Hans-Joachim, ‘Germany’s Identity Problems as Reflected in Nineteenth-Century Literature’, in MHRA Working Papers in the Humanities, 2 (2007), 30–48 <https://www.mhra.org.uk/publications/wph-2>

Step 9. Electronic publications cited by URL rather than DOI must give an access date. For this demonstration, it's today. Note the format, Day Month Year, with the Month spelled out in full.

Hahn, Hans-Joachim, ‘Germany’s Identity Problems as Reflected in Nineteenth-Century Literature’, in MHRA Working Papers in the Humanities, 2 (2007), 30–48 <https://www.mhra.org.uk/publications/wph-2> [accessed 7 December 2023]

And that's the finished bibliography entry. Note that there's no final full stop.

So how about citations in footnotes or endnotes?

In standard MHRA style, the first time the work is cited in a note, it should be cited in full. This looks very like a Bibliography entry, but:

• The author's name doesn't always come first: only for monographs. For collections and editions, the title comes first.
• Even if the author's name does come first, it's back to being the right way round, so it's Forename Surname, not Surname, Forename;
• Unlike Bibliography entries, notes are punctuated as sentences, and usually end in full stops.

Suppose we want to cite a passage on pages 24 to 27:

³⁴ See Hans-Joachim Hahn, ‘Germany’s Identity Problems as Reflected in Nineteenth-Century Literature’, in MHRA Working Papers in the Humanities, 2 (2007), 30–48 <https://www.mhra.org.uk/publications/wph-2> [accessed 7 December 2023], pp. 24-27.

But in any subsequent notes, a heavily abbreviated form is used:

³⁷ Compare Hahn, p. 17.
