Q. Why was the twentieth century called the ‘Era of the Book’?

(बीसवीं शताब्दी को ‘किताओं का युग’ क्यों कहा गया है ?)
Answer: The twentieth century was called the ‘Era of the Book’ because at that time there were books about everything. One could find a book on any subject from anteaters to Zulus.

(बीसवीं शताब्दी को ‘किताबों का युग’ इसलिए कहा गया है क्योंकि उस समय प्रत्येक चीज के बारे में पुस्तकें थीं। उस समय प्राचीनतम जानवरों से लेकर जुलू लोगों तक सभी पर पुस्तकें मिल जाती थीं।)
