The cosmic baryon budget is revisited using modern observations that have become available since our first publication. I also present an estimate for the heavy element abundance. An increased accuracy in the accounting of the baryon budget reveals `missing baryons', which amount to ≈ 35% of the total. This would provide an interesting test for models of the cosmic structure formation.
