Although some countries have already established models to try to solve the problem of orphan works, others are still discussing possible options. The paper explores the current situation of the schemes in place internationally to deal with the problems associated with orphan works and how these are being applied by cultural institutions regarding the digital dissemination of their collections. The methodology consisted in a systematic review of the research results as an exploratory analytical technique for the collection of relevant information. Results highlighted that global situation is uncertain and none of the formulas studied enables full and effective digitisation and digital dissemination of the world’s cultural heritage. Further advances are necessary for the creation of diligent search procedures.engbook parthttps://doi.org/10.1007/978-3-319-78105-1_73open access025:004004.65:061347.78:004Orphan worksDigitisationOnline DisseminationLibrariesCultural heritageDocumentary HeritageCopyrightDiligent SearchBibliotecas digitalesDocumentos electrónicosRepositorios institucionalesPropiedad intelectual
