SOMERSET WEST, South Africa: Heavy reader? Maybe this South African rugby book weighing 35 kg and measuring half a meter by half a meter is for you. Got a spare $13,500, though?

There are just 100 leather-bound Captains’ Editions of the recently released “Springbok Opus,” which tells the complete story of South Africa and its national sport dating to the 1860s, said Craig Mark, the sales and marketing director for the book.

Its 630 pages and more than 150,000 words long, took four years to put together, and the books are autographed by 45 current and former star players.

The Springbok Opus is the latest in a line of collectable sports books aimed at the really, really dedicated fan. This one’s the first in rugby, and there have been others on the Super Bowl, Formula One, Ferrari, and Manchester United.

The South African rugby book may turn out to be a bargain. Versions of the Ferrari F1 team opus, with covers encrusted with diamonds, went on sale at $275,000.
