Welcome to CLB-LOD Wikibase, a Wikibase instance hosted on wikibase.cloud. This is a sandbox for working towards MARC bibliographical records LOD-ification, with the final goal of their integration in Wikidata, with CLB Czech Literary Bibliography MARC-XML data as showcase. This is a project carried out in the framework of DARIAH WG Bibliodata.
