  1. Introduction

  2. This is a catalog of
    articles on cosmology that yours truly identifies as signficant/useful. It's a curated catalog.

    Probably, most articles are just useful: intelligible, educational, NOT likely contenders for eternal truth.

    Yours truly tends to avoid quantum cosmology, unless they are truly intelligible---quantum cosmology has a lot of byways which must be explored---you got to keep trying---but most of which must wrong.

    Papers yours truly as read at least in part or heard discussed: *
    Papers yours truly thinks are particularly useful: **
