user-1: Looking for a primary source (an actual historical text) or a secondary source (a formal study of a historical text or texts), on how it is that this world is or isn't a "pure land".
Presumably the Buddha Sakyamuni has or had a pure land? I've read a lot of Buddhist scholarship, so please don't be shy in recommending anything at all, in English or translatable somehow.

user471: The bolded statements below show immediate birth into the Pure Land in this life itself.
The way I see this explanation is that the Pure Land is a "place of mind".
From Japanese Pure Land Philosophy on Stanford Encyclopedia of Philosophy:

Thinkers like Shinran and Shōkū, however, both understood the
utterance of nembutsu to be fulfilled practice because it arises from
the oneness of being and Buddha expressed as shinjin or taking refuge.
Further, because of this oneness, a person’s attainment of birth in
the Pure Land is completely settled in the immediate present.
The effects of the oneness are manifested not only in the occurrence
of birth in the Pure Land at death, but also in various ways in
present life. Shōkū speaks of a variety of benefits received in the
present by the person of the nembutsu, including the elimination of
the effects of past evil acts, extension of life, avoidance of various
calamities, protection of buddhas, seeing of Amida, and so on. One
should not pursue such benefits for their own sake, but they naturally
come about for the person of the nembutsu whose birth in the Pure Land
is settled. Thus, to express the condition of the nembutsu
practitioner, Shōkū even distinguishes two types of Pure Land “birth,”
“immediate birth” (sokuben ōjō) while remaining burdened with
afflicting passions in present life and birth into the Pure Land at
the time of death (tōtoku ōjō).
