IX. LIBRARY 
19. The library accommodation remained in the unsatisfactory situation 
stated in the previous Annual Reports. The prospect of relief recorded in 
last year’s report did not materialise with the suspension in September, of 
the contract in September for the construction of the building to house the 
library. Work is expected to restart early in 1968. The library accession 
register showed a holding of 9,052 bound volumes by the end of the year, in 
addition to which there is an extensive holding of unbound volumes, separates 
and other miscellaneous materials. The Gardens' Bulletin, Singapore, was 
exchanged with 318 addresses throughout the world.
