This title resulted from a merger of two 1950s fanzines: Ron Smith’s Inside and Roy Squires' Science Fiction Advertiser. It featured early Science Fiction/Fantasy-related literary criticism. This type of analysis was especially significant because it was occurring in an era before the genres had begun to receive serious attention in scholarly literature. The editorship was later passed to Leland Sapiro, who renamed the publication Riverside Quarterly in 1964. RQ continued to focus on academically-minded criticism. In 1956, Inside and Science Fiction Advertiser won the Best Fanzine Hugo award; it was the second publication to receive this distinction.
