[目的/意义]随着主文献从静态的纸质汇编向动态的数字知识基础设施演进，其价值具有多层、多维的特性。通过对主文献价值生成、价值维度与实现路径的系统性剖析，在理论层面，完善并丰富主文献价值理论体系；在实践维度，为推进主文献建设的高质量发展提供坚实的学理参照。[方法/过程]首先，通过文献梳理与理论分析，阐释主文献价值生成的逻辑；其次，从具体的服务场景出发，揭示主文献的多维价值表现；最后，从机制、技术以及战略适配等层面，探讨主文献价值实现的路径。[结果/结论]主文献价值植根于坚实的现实条件与深刻的内在逻辑，是对当前知识生产模式转型与学术创新发展客观要求的积极响应。主文献价值的表现有三个维度，第一层为基础支撑价值，主要包括文献精选价值；第二层为基础赋能价值，主要包括教育教学价值、学术评价价值、助力原创价值、知识传播价值；第三层为战略引领价值，主要包括导向引领价值。要实现这三层价值，需紧扣各层面的核心定位，通过构建“精选机制—应用场景—战略适配”的联动体系，形成三层价值相互赋能、协同发力的完整闭环。

[Purpose/significance] As classic literature evolve from static paper compilations to dynamic digital knowl⁃edge infrastructure, their value possesses multi-layered and multi-dimensional characteristics. Through a systematic analysis of the generation, dimensions, and realization paths of classic literature value, this paper aims to improve and enrich the theoretical system of classic literature value at the theoretical level, and provide a solid theoretical reference for promoting the high-quality development of classic literature construction at the practical level. [Method/process] First, through literature review and theoretical analysis, the logic of classic literature value generation is explained; sec⁃ond, starting from specific service scenarios, the multi-dimensional value manifestations of classic literature are re⁃vealed; finally, from the perspectives of mechanisms, technology, and strategic adaptation, feasible paths for realizing the value of the main document were explored. [Result/conclusion] The value of classic literature is rooted in solid re⁃alities and profound internal logic, and is a positive response to the objective requirements of the current transformation of knowledge production models and the development of academic innovation. The value manifestation of classic litera⁃ture has three dimensions: the first layer is the basic support value, mainly including the value of carefully selected doc⁃uments; the second layer is the basic empowerment value, mainly including the value of education and teaching, aca⁃demic evaluation, supporting original creation, and knowledge dissemination; the third layer is the strategic guidance value, mainly including the guiding value. To realize these three layers of value, it is necessary to closely adhere to the core positioning of each layer and form a complete closed loop of mutual empowerment and synergistic efforts by build⁃ing a linkage system of "selected mechanisms - application scenarios - strategic adaptation".
