Use the run-in format when the quoted matter is not more than fifty words or five lines long (longer quotations should be set in block format):
The quotation remains within the body of the paragraph.
Because the run-in format does not require indentation, the writer enjoys some latitude in positioning the clause or phrase that introduces the quotation, also called the annunciatory element.
Note that when a quotation is interrupted by other matter, the quotation marks are repeated before and after each part of the quotation:
If you decide to insert the annunciatory clause between two items that were separate sentences in the original or have become separate sentences in the quotation, capitalize the first word of the second sentence, i.e. of the second part of the quotation:
Note that in the second example the annunciatory clause ends with a period and not a comma.
When a quotation within a sentence is preceded by that, do not capitalize the first word (unless it is a proper noun or adjective):
