Literary critics, asked to summarize their research, are often asked, ‘Who are your authors?’ Everywhere and Nowhere cleverly baffles this question and turns our attention to anonymity. Bracketing out the author, Mark Vareschi brings into sight other features of publication: namely, networks of writing and reception and a complex of print and performance. He works impressively with bibliographic records, booksellers’ catalogs, advertisements, and paratextual material, like tables of contents. His careful bibliometric work establishes changing percentages of anonymous publication across decades and genres. This is fresh, compelling, detail-rich scholarship and essential reading.
