First insights • About 27% of all records in BASE arejournalarticles (exactnumbercannotbedeterminedbecauseoflackingmetadata) • Share differsfromcountrytocountry • Providing comprehensiveand valid information on OA statusandlicenseinformationis still a challenge
Agenda • Introduction • BASE • DOI pretest • Conclusions
Basic questions • Howmany DOIs are in the BASE index? • Howmany DOIs oftheOpenAPCdatasetcanwe find there? • HowmanyOpenAPCs-DOIs do we find on IRs?
First results • Out of 149,8 milliondocumentsand 7,175 sourcesthereare 43.051.773 DOIs indexed in BASE • Top ten: Data Cite(15,1 mill.), PubMed Central (3,3 mill.), DOAJ (2, 8 mill.), HighWire Press (2,4 mill.), Elsevier SD (1,3 mill., only OA articles via Crossref), ), Zenodo(1 mill.), ArXiv (822 k), ETH e-periodica, HAL, Dara
