There was an event at one of the biggest bookstore in Tokyo tonight. They would exhibit their sales ranking of the computer related books published during the last year. Thankfully, in the ranking, there were some books which I edited. However, everybody knows that the ranking itself tends to be a bit biased every year. Such bias can't be avoided because the customers' expectations are different from each bookstore, no matter how big the store is. So it wasn't the ranking the attendee, including me, were interested. Instead, we were looking forward to hearing the talk of the main presenter. He managed to review hundreds of books merely in two hours this year, and I found a few books I should read someday.
