The traditional MARC bibliographic format extremely used for library bibliographic data from becoming network information resources. The library must solve how to attracts the users from network application services back to the library system. The present paper discusses SchemaBibEx, which is the bibliographic resource description extension of Schema.org, as the powerful tool for the library to solve this problem. By analysing the linked data model, vocabularies, tools, and services, the paper explains its originality, openness, global unity, and economically. It also discusses its complementary relationship with BIBFRAME which is the next generation of the bibliographic frame format. SchemaBibEx is not the replacement of MARC but will become a two-way communication bridge between library bibliographic data and information user network
