British Library partners with Google Scholar or research articles

"Search results will be matched against the Library's holdings and where a match is made, users will have the option to obtain articles held via the British Library’s online document ordering interface, British Library Direct.

My question is are these holding just print holdings or on-line holdings too?

"Lynne Brindley, chief executive of the British Library, said: "By partnering with Google Scholar, the British Library will enable users to identify and locate relevant articles more effectively than has previously been possible. By linking results to our pay-as-you-go service, British Library Direct, we’ll provide a swift and easy means for them to have the items they require delivered straight to their desktop."
