Arrange the following networks in the ascending order of geographical coverage :

(i) OCLC
(ii) INFLIBNET
(iii) CALIBNET
(iv) ASTINFO

  • A.(i), (ii), (iv), (iii)
  • B.(ii), (i), (iv), (iii)
  • C.(iii), (ii), (iv), (i)
  • D.(i), (iv), (ii), (iii)

Answer: C

The ascending order is (iii), (ii), (iv), (i): CALIBNET, INFLIBNET, ASTINFO, OCLC.

CALIBNET is the Calcutta Library Network, a city network. INFLIBNET links university libraries across India, a national network. ASTINFO is UNESCO's regional network for science and technology information in Asia and the Pacific, covering a region of many countries. OCLC is a worldwide library cooperative.

Moving from city to nation to region to world gives this order. The other options begin with OCLC or INFLIBNET, which cover more ground than CALIBNET, so they are wrong.
