These are not details that are important to your essay grade, with the possible exception of #7—please, please do not spend time fixing the way you quote Shakes when you could spend that time enriching the textual analysis in your essay.
So, 7 quick rules:
1. Use numerals to indicate sonnet numbers
I can’t read a sentence beginning “In Shakespeare’s sonnets numbered one hundred and thirty-five and one hundred and thirty-six…” without thinking that you’ve just wasted a line of text you could have used to identify the themes or images central to those sonnets.
Hence:
In Sonnets 1 through 18, the speaker uses rhetorical and dramatic techniques to try to persuade the fair youth to procreate.
2. Only capitalize sonnet when referring to a specific one
Such as:
Scholars have suggested that Sonnets 71 and 72 best encapsulate the death and poetry theme that runs throughout Shakespeare’s sonnet sequence.
3. Replace line breaks with slashes (/)
Example:
In apparent opposition to the poetry-as-immortality theme, the speaker equates his name with his body: “My name be buried where my body is, / And live no more to shame nor me nor you” (72.11-12).
4. Preserve punctuation and capitalization
Exception 1: remove the punctuation mark from the end of your quotation so that you can fit it more neatly into your own sentence.
Exception 2: diacritical marks indicating enunciation (e.g. “believèd,” 141.12).
Exemplum:
The speaker suggests that earlier love poetry tended to praise people in parts: “in the blazon of sweet beauty’s best, / Of hand, of foot, of lip, of eye, of brow”; the speaker distinguishes this praise from the more holistic beauty of his lover (106.5-7).
(By the way, the punctuation we see in our edition is not Shakespeare’s. Like spelling, punctuation in the 16th and 17th centuries was erratic. Compare Sonnet 129 as it appeared in 1609—page 133—with the version that appears in our book and note how modern editors have made free with commas, colons, and semicolons.)
5. Cite line numbers after quotations
See points 3, 4, and 6 for examples.
Observe:
- The citation is part of the sentence to which it refers, and is hence not separated from that sentence by a period: “…of his lover (106.5-7).”
- As the citation is the last item in the sentence, it is followed by a period. The period is exterior to the end parenthesis.
- Exception: if you quote 4 or more lines, format your citation as described in point 6 below. (The citation is not part of the sentence in that case.)
- When the sonnet number is not indicated by context, which is the case in points 3 and 4, that number goes before the line number thus: (106.5-7).
- If the sonnet number had been indicated by context it would not have to be given, e.g. “Sonnet 106 ends with the phrase ‘tongues to praise’ (14).”
- You don’t have to write “line” or anything—when I see a number in parentheses after a verse quotation I assume that number refers to a line.
6. Quoting 4 lines or more? Don’t.
In a short essay you need all the space you can get.
Still, here’s the rule: quotations 4 lines or longer should be left-indented an inch; the right margin does not change, nor does the spacing. (That’s right: double-space block quotations.) E.g.:
Shakespeare exhibits his death fetish at the beginning of sonnet 71:
No longer mourn for me when I am dead
Than you shall hear the surly sullen bell
Give warning to the world that I am fled
From this vile world, with vilest worms to dwell. (1-4.)
7. Quote Shakespeare correctly
Because this essay asks you to look closely at the language of the sonnets, correct spelling and punctuation count enormously.
