Throughout the 19th century, stereotyping of work by sex had restricted women's employment. (Woloch, 2002). Is this a quote or paraphrasing?

I can't tell. Is it exactly, word for word, what is in a book or article?

To determine whether the sentence you provided is a quote or paraphrasing, we would need more information. The sentence itself does not include any quotation marks, which suggests that it is likely a paraphrase rather than a direct quote. However, without knowing the exact source and context of the sentence, it is difficult to make a definitive determination. To properly cite the information and avoid plagiarism, it is always best to refer to the original source and follow the specific citation guidelines required by your academic institution or writing style guide.
