In the hobby of book collecting, the primary difference between author and subject collections lies in the collector's focus and scope.1

Author Collections: The collector concentrates on gathering the works of a specific author. This approach may involve acquiring every form in which an author's work has been published, or it may be narrowed to focus on a particular phase of their career or even just one or two specific titles.1
Subject Collections: The collector focuses on a specific theme or field of interest. These can range from broad categories like American literature or classics to highly specialized topics such as chess, nuclear energy, or even specific types of publications, such as books issued in serial parts.1

While author collections are defined by the creator of the text, subject collections are defined by the content or thematic relevance of the books. Both styles allow collectors to marshal significant facts regarding the history of society and human endeavor.1
