Is it? I wouldnt say that MCO and the likes really hold that much more info than say Euwe's 12 opening books or Pachman's Eroffnungen. Sure it runs deeper now, but the further they get the more they forget.
It's true that a lot of old lines are forgotton. Forgotten, because there was a negative conclusion about them, and they were dropped from the manuals to save space. Then somebody has to rediscover it all.
But I think that the revolution in modern theory has mostly to do with computers. You can store vastly more information, so why bother to prune it? It's much easier to access; and theoretical advances, at least in lines where computation is important, is facilitated by machines. Also there are so many more strong players now, and so many more games between such players to contribute to the advance of theory.
But really I'm surprised that anyone would argue this point. Compare MCO-10, the bible of the 1960s and early 70s, to the multivolume ECO sets that succeeded it. Yet today, ECO sits on the bookshelf, more or less inadequate to capture the enormous breadth and continual, chaotic ramification of modern theory.
I've been preparing a fairly comprehensive set of computerized notes on Alekhine's, and I've been struck by the vastness of existing theory on just this one defense, which itself has become something of a backwater. I have in my files much more than would fit in a good-sized book. Maintaining equally comprehensive notes on the Closed Spanish or the Najdorf Sicilian would be a full time job, or very nearly.
It's no wonder that the books written today tend to be summary, introductory works, like the admirable
Starting Out series. There simply is no way to do justice to the theory, even of just one major system, in a book. And as soon as it's printed, it's obsolete.
