Questions
Why do Crossref and OpenAlex give different numbers?
Crossref counts citations from references deposited by publishers; OpenAlex also reads other sources. Neither is complete, so both are shown.
Is this the same as Web of Science or Scopus?
No. Those databases are not open; their counts are usually different.
