The digital era offers a plethora of opportunities for readers to exchange opinions, share reading recommendations, and form ties with other readers. This communication often takes place in online environments, which presents reading researchers with new opportunities and challenges when investigating readers’ reading experiences. What readers do with what they read is not a new topic of scholarly debate. As early as the 14th century, when scribes questioned how their readers understood their words, readers have been scrutinized. Contemporary reading investigations and theory formation began in earnest in the 1920s with I. A. Richards’s argument that the reader should be considered separate from the text. In the 1930s, Louise Rosenblatt furthered the discipline, using literature as an occasion for collective inquiry into both cultural and individual values and introducing the concerns for the phenomenological experience of reading and its intersubjectivity. While there is no universal theory of how readers read, more recent scholarly discourse illustrates a cluster of related views that see the reader and the text as complementary to one another in a variety of critical contexts. With the advent of social media and Web 2.0, readers provide researchers with a host of opportunities to not only identify who they are, but to access in profound ways their individual and collective responses to the books they read. Reader responses on the Internet’s early email forums, or the contemporary iterations of browser-hosted groups such as Yahoo Groups or Google Groups, alongside book talk found on platforms such as Twitter, Facebook, and YouTube, present data that can be analyzed through established or newly developed digital methods. Reviews and commentary on these platforms, in addition to the thousands of book blogs, Goodreads.com, LibraryThing.com, and readers’ reviews on bookseller websites illustrate cultural, economic, and social aspects of reading in ways that previously were often elusive to reading researchers. Contemporary reading scholars bring to the analytical mix perspectives that enrich last century’s theories of unidentified readers. The methods illustrate the fertility available to contemporary investigations of readers and their books. Considered together, they allow scholars to contemplate the complexities of reading in the past, highlight the uniqueness of reading in the present, and provide material to help project into the future.
