The publication of the Foundation saga spans 66 years and multiple authors. Of course Isaac Asimov laid the “foundation” with the first trilogy and multiple books thereafter. Bear and Brin also officially contributed to the canon after Asimov’s death. Looking for a place to start? I would suggest beginning with the original trilogy.
