國會助理主要協助立法委員行使各項立法職權與問政工作，扮演著重要的幕僚角色。本研究以國會圖書館為研究個案，邀請10位以法案研究為主之國會助理參與深度訪談，深入瞭解國會助理資訊尋求行為之情境與特性，及其與資訊環境的互動與影響。研究結果顯示：達成立法委員法案研究與選民服務之任務，是國會助理之主要立法資訊需求情境；不同層次的立法資訊需求，會影響國會助理選用立法資訊的管道和類型。本研究亦發現國會圖書館網站資源，為國會助理開始蒐集立法資訊之管道，並以個人習慣熟悉的途徑獲得更多的資訊；國會助理同時會依據個人資訊需求特性，選擇書面或口頭的資訊為解決方案；同時國會助理習慣自己展開資訊尋求並自我判斷資訊適用性。

Congressional assistants play an important role in helping legislators deal with their legislative duties and political affairs. This study aims to explore and analyze the characteristics of congressional assistants' information-seeking behavior and context. Results of this study suggest that congressional assistants search for legislative information mainly in order to make thorough studies of issues related to bills under discussion and to provide prompt and satisfactory services for civilians. Specific needs in different contexts will influence congressional assistants' decision on information acquisition and adoption. In addition, the process of their legislative information-seeking is likely to be swayed by social or personal factors. The web site of the Parliamentary Library frequently serves as the first source of legislative information-seeking, though the searching methods applied by congressional assistants may vary from one person to another. Congressional assistants further seek specific information through various sources, judge the compatibility of the sought information, and select documents in oral or printed form to fit in with particular contexts.
