ON THE SYSTEM OF CATALOGUING ADOPTED IN THE 
SARAWAK MUSEUM 
In the year 1874 ап American, Mr, Melvill Dewey, invented 
and published a system for class ifying and cataloguing scienti- 
fic and other literature by means of employing decimal numbers, 
this system is known as the Dewey Decimal System. Curiously 
enough it has received but a small amount of attention in Eng- 
land and her ndencies, ost astonishing fact when one 
compares its perfect method and simplicity with the s 8 
win vogue in the majority of large home and colonial libra- 
ries, Mr. Dewey is in short the Bertillon of scientific catalogu- 
ing, less fortunate than his distinguished prototype, inasmuch 
as he has still to receive a wide-spread recognition. 
e sy 
literature has been produced, into groups; to each group a 
number is assigned; each group is subdivided and each sub- 
division is алина by a decimal number, following the 
group number, Thus, under such a number as 600 would be 
found all works dealing with easy: a pré ge of this, 
Europe, would have the number 600.1; Asia, 600.2 P 
countries making up these main divisions would again 
number—England 600.11, Scotland 600.12, зе 600. 13, 
etc., etc., whilst still greater subdivision can be provided for by 
the addition of another decimal, thus :— Bedfordshire 600.11.1. 
Naturally enough ey modifications of this system have 
been suggested and tried.
