I find Wikipedia a great data base giving information which no other encyclopedia would give.
I do my bit when somebody tries to mutilate (not edit) an article by, for instance, deleting whole paragraphs or links just because he/she does not like it.
The eastern grey kangaroo (Macropus giganteus) is a marsupial found in the eastern third of Australia, with a population of several million. The eastern grey kangaroo is the second largest living marsupial and native land mammal in Australia, with adult males weighing around 50 to 66 kg (110 to 146 lb) and females weighing around 17 to 40 kg (37 to 88 lb). Like all kangaroos, it is mainly nocturnal and crepuscular, and is mostly seen early in the morning, or as the light starts to fade in the evening. In the middle of the day, kangaroos rest in the cover of the woodlands and graze there. Kangaroos are the only large mammals to hop on two legs as their primary means of locomotion.
