文學文獻學是文學路究的根柢之一，卻非文學研究本身，以前者取代後者，貌似知識廣博、功力精深，實屬具體問題意識錯置所致。張協平的資料極貧乏，難有考據文章可作，這種事實現象並非缺憾，反而應當被視為優點，因為研究者桴可將心力集中於張協的作品上，一探六朝人何以對其代表作：〈雜詩〉十首評價甚高，這十首的特異之處所在，以致能在古詩的宮室中與潘、陸並「坐於廊廡之間」。

Literary bibliography is one of the fundamentals of literary research rather than literary research itself. It may seem erudite and profound to substitute the latter with the former. Nevertheless, such a substitution is actually due to the misplacement of the subject matter. Biographical information about Zhang Xie is so rare that evidential research almost becomes unfeasible. This fact is not a weakness for research; it is rather a forte – researchers are allowed to focus on Zhang Xie’s works themselves, to find out how readers of the Six Dynasties found uniqueness in and extol the ten poems of his masterpiece “Zashi” (Miscellaneous Poems), which rivals Pan Yue’s and Lu Ji’s works in the world of ancient style poems.
