As elsewhere, in medicine it has become evident that the "pure" ideal of on-line, full-text real-time computerized systems offers no panacea for the diverse information problems of researchers, practitioners, and administrators. More flexible, efficient and economical possibilities are available in the form of "hybrid" systems of computers and other techniques, such as micrographics and COM. There are a number of alternative strategies. LORBAS is one family of such systems. LORBAS is based on a mini-microfilm technique (reduction ratio to 250:1, up to 200,000 pages per liter), permitting rapid digital random access to every page. The computer is used off-line for the administration of the system and for generating a variety of retrieval aids which are worked into the film inventory (through COM). Numerous user stations can be equipped with the full document basis(incl. the retrieval aids), and operated off-line. On-line linkage is optional on every desired level of sophistication.
与其他领域一样，在医学领域，有一点已经很明显，即在线、全文实时计算机化系统的“纯粹”理想并不能为研究人员、从业者和管理人员所面临的各种信息问题提供万灵药。以计算机与其他技术（如缩微摄影和计算机输出缩微胶片）相结合的“混合”系统形式，有更灵活、高效和经济的可能性。有许多替代策略。LORBAS就是这类系统中的一个系列。LORBAS基于一种缩微胶片技术（缩小比例为250:1，每升可达200,000页），允许对每一页进行快速数字随机访问。计算机用于离线管理系统，并生成各种检索辅助工具，这些工具被编入胶片目录（通过计算机输出缩微胶片）。许多用户站可以配备完整的文档库（包括检索辅助工具），并进行离线操作。在任何所需的复杂程度级别上，在线链接都是可选的。
