Nine months later, I am now able to substantiate my claim. A search on this platform reveals that the third spot globally, among authors with the most indexed books in my field, is shared by several individuals, each with a total of 12 indexed books. However, the identities of these authors and the dynamics of their production are irrelevant. Even if, by some improbable chance, they were to start publishing three books per year, they would still fall short of breaking the record by 2029—the year of my retirement.
The only real danger lies in the professor (at a university in Australia) who occupies 2nd place in the world, holder of an impressive Scopus h-index=94, and who has 20 indexed books. It turns out, however, that he needed 20 years to produce them, so it will not be now, at almost 70 years of age, that he will start producing at a rate 300% greater than what he has produced in the last two decades. But even if by some miracle this improbable thing were to happen, it wouldn't be possible to break my record, for the simple reason that I haven't stopped yet, nor will I stop producing anytime soon.
