No, unfortunately. I think those newspapers are kept there, but they are not online. They're only consultable by the Library's staff and by visitors.
I know for sure that in several libraries it happens the same. I mean: Hemeroteca Municipal de Lisboa owns the old copies of Record and A Bola, Biblioteca Nacional de España keeps Marca, Biblioteca Nazionale Braidense has La Gazzetta dello Sport, Library of Congress owns several copies of Népsport, Bibliothèque Royale de Belgique owns Le Soir, while Sport (a famous Serbian newspaper) is available at National Library of Serbia.
But unfortunately, at the moment, none of them is available online.
