In-text citations generally require you to provide Author, Date, and Location (i.e. page numbers) when you first reference a document in your writing. Subsequent references/citations do not always require all of this information. Follow these basic guidelines for handling subsequent citations.
If you first cite a source in the text of a sentence, you do not need to include the Date in any subsequent citations that are also in the text of the sentence. You should include the Date if you later cite the document in parentheses.
APA Manual pp.265, Section 8.16
If you first cite a source in parentheses, you must provide a full citation for all subsequent citaitons.
