This study proposes to discuss the annual collections of poems published by Erya, a Taiwanese Publisher, from 1983 to 1993 (from the 1982 Collection of Poems to the 1991 Collection of Poems.) Edited by Mo Zhang, Xiao Xiao, Ming Xiang, Ruiteng Li, Yang Xiang, and Hanliang Zhang by turns in a decade, the collections are representative annual anthologies as well as important research materials on the development of Taiwanese poems. Based on Robert Escarpit's sociology of literature and Pierre Bourdieu's field theory, this study explores the collections' influence on shaping canons as well as the chief editors' operation of power and principles on editing. It also examines the relation between the collections and the trends in Taiwanese poems in the 1980s.As for the editing of Erya's annual collections of poems, Mo Zhang was authorized by Di Yin to choose editors. Before inviting editors, he took into consideration which poetry association and generation they belonged to, along with their positions in the poetry circles. To pursue a long-term operation of the collections, editors formed an editorial board to choose poems together, and they took the position as chief editor by turns every year. Despite their varying ideas of poetry, they could fully exchange opinions and follow the guiding principles they made. However, the poems in the 1988 Collection of Poems and in the collections that followed were chosen by the chief editor only, showing his personal taste.To discuss the outer factors affecting the collections, this study examines Erya's operation strategies, the media showing the collections, and the composition of the poets in the collections. Erya's publications were popular before 1988. However, after the martial law was lifted, sales of literature works dropped gradually. Although the sales volume of any of the collections remained above 3,000, Di Yin painfully decided to cease the publication of the collections because of his unwillingness to break the function of reprint fees. As for the media showing the collections, this study finds that certain media were favored due to many reasons. As for the composition of the poets, their average age was about 40, and they were born between the Japanese colonial period and the 1960s. The collections also showed the important poets during that period.It is difficult to clearly understand the relation between the collections and the history of Taiwanese poetry. By classifying poems based on their subject matters, this study shows the unique characteristics of Taiwanese poems during 1982 and 1991. It not only reveals that the collections favor realism, universality, and poems that represent news or an era, but also shows the trend toward localization and post-modernism in poetry writing. Although included in the collections, a poem needs to be examined many times before it can be deemed as a classic work. Albeit the collections can shape canons, their influence has its limitation. With careful examination, this study finds that not many poems that win literature awards are included in the collections. The collections encourage novices when including their poems that win campus literature awards, and reaffirm poets' accomplishment when including their poems that win national literature awards. Finally, by reviewing the collections and other important anthologies, this study finds that 26.4 percent of the poems in the collections are later included in other anthologies, and the finding shows that the collections serve as important references.
