Attribution & Citation

Primary Source

The original record of a quote — the book, letter, speech, or recording in which it first appeared.

A primary source is the original, first-hand record of a quotation. For a book, it is the book itself, ideally the first edition. For a speech, it is the transcript or recording. For a letter, it is the manuscript or the verified printed edition. Anything else — a biographer's recollection, a newspaper paraphrase, a later anthology — is a secondary source.

Quotation research begins and ends with the primary source. If the line is in the book on the page the citation gives, the quote is verified. If it is not, every later use of the line is suspect.

When the primary source is genuinely unrecoverable — for instance, a remark made privately in conversation — the next best evidence is a contemporaneous secondary source: a letter from someone who was present, written soon after.

Example

— Martin Luther King Jr. · 'I Have a Dream' speech, Aug 28 1963 — primary source
