感知信息可获得性是一个统一的概念，用于设计和评价各种信息系统和服务。这项实地研究测量了终端用户对三种信息来源(基于计算机、图书馆和个人)的感知，包括三个样本的个人。结果表明：1)可及性是一个多维的概念，包括对来源的物理接触、与来源的接口以及对潜在相关信息的物理提取能力；2)对可获得性的感知受到对来源和背景因素的先前经验的影响。
Perceived accessibility to information is proposed as a unifying concept for the design and evaluation of a wide variety of information systems and services. This field study measured end‐user perceptions of three sources of information (computer‐based, libraries, and individuals) for three samples of individuals. The results suggest that 1) accessibility is a multidimensional concept encompassing physical access to the source, the interface to the source, and the ability to physically retrieve potentially relevant information, and 2) perceptions of accessibility are moderated by prior experience with the source and contextual factors.
