It is a household classic and has been a masterpiece in the American literature and world literature. In the contemporary epoch, investigation into the canonization of Walden can be dynamic, progressive and longlasting. This treatise intends to furnish an all-round scholarship on the canonization of Walden from two perspectives: recognizance of Walden in America, development of literature theory.展开更多

Theoretically, anthology criticism focuses on three main areas： the preface and postscript, the annotation of the anthology, and the works selected for inclusion in the anthology. Anthology criticism is unique in its methodological synergy, including the direct and indirect communication of literary judgments and the amalgamation of critical theory and practice. This paper argues that the anthology as a form of literary criticism possesses great theoretical value; it sheds light on the development of literary concepts and forms, as well as suggesting the nature of literary transmission. Therefore, the literary anthology plays a key role in the canonization of Chinese literature.展开更多
