Response to “Making Search Engines Notice” by Le Yang

Purpose – Google Scholar has difficulty indexing the contents of institutional repositories, and the authors hypothesize the reason is that most repositories use Dublin Core, which cannot express bibliographic citation information adequately for academic papers Google Scholar makes specific recommendations for repositories, including the use of publishing industry metadata schemas over Dublin Core This paper aims to test a theory that transforming metadata schemas in institutional repositories will lead to increased indexing by Google ScholarDesign/methodology/approach – The authors conducted two surveys of institutional and disciplinary repositories across the USA, using different methodologies They also conducted three pilot projects that transformed the metadata of a subset of papers from USpace, the University of Utah's institutional repository, and examined the results of Google Scholar's explicit harvestsFindings – Repositories that use GS recommended metadata schemas and express them in HTML m

Invisible institutional repositories: Addressing the low indexing ratios of IRs in Google Scholar

This study analyzed the search results of four main Internet search engines on three newly created digital collections at Texas Tech University Libraries, in order to assess the search engine indexing on metadata and PDF files of digital items that are published in the institutional repository. The exploratory study found that only one search engine discovered PDF files, while the others only discovered metadata. The results of the study also suggested that metadata and PDF files can supplement each other to facilitate discoverability of the digital collections on search engines, and revealed some findings that are contradictory to conclusions in previous research.
