Coudln't find Steven Weinberg's "a model of leptons"

[rar0308]

i searched Steven weinberg in google scholar.
it returns many articles but "a model of leptons"
why does "a model of leptons" not appear in google scholar?
is there some mistake or some reason for it not to appear?
it seems odd that the famous articles is not found
