Open access is also provided by links to the Institutional repository of the awarding body, for example the full text of John Sulston's PhD thesis[18] is available by following links in EThOS to the Apollo repository of the University of Cambridge.

Doctoral advisor metadata can be used in academic genealogies like academictree.org,[28][29] Wikidata[38][30] and the Mathematics Genealogy Project. Academic genealogies in Wikidata are built using the doctoral advisor relation (Property:P184).[31] Searching EThOS metadataWhere present, metadata can be used as search criteria. So for example, in addition to a basic search,[4] an advanced search facility allows users to search for theses by publication year, awarding body, author's given name, surname, thesis title, doctoral advisor and various other metadata.[32] Data in EThOS can also be accessed programmatically (by machines) using the Protocol for Metadata Harvesting (PMH) from the Open Archives Initiative (OAI),[33] DataCite[34] and its Application Programming Interface (API).[35]===Types of thesis included===As well as indexing Doctor of Philosophy theses, EThOS holds records of other kinds of doctorates including* Doctor of Medicine (MD) theses, for example Pensée Wu's thesis.{{cite thesis|degree=MD|publisher=Imperial College London|title=Muscular dystrophy cell therapy : an in utero approach using human fetal mesenchymal stem cells|first= Pensée|last=Wu|date=2009|url=http://ethos.bl.uk/OrderDetails.do?uin=uk.bl.ethos.508625|website=ethos.bl.uk|oclc=930655636|hdl=10044/1/4726}} {{open access}} |
