The National Library safeguards the published heritage of Singapore. This is carried out through the deposit of materials published in Singapore under the National Library Board (NLB) Act (Chapter 197, No. 5 of 1995, Part II Section 10).

Known as Legal Deposit, it ensures that Singapore’s published heritage is collected, preserved for posterity and made accessible. It is an important function as it helps to keep knowledge and stories of our culture, our heritage, and our history alive for future generations of Singaporeans. Two copies of every publication published or produced in Singapore and made available for sale or public distribution in Singapore are required for deposit with the National Library within four weeks from the date of publication.

Recognising that many publishing activities are increasingly moving to digital, the National Library Board Act was updated to include electronic publications under Legal Deposit. The amendments came into force on 31 January 2019. For more information about depositing electronic publications, please refer to Digital Legal Deposit.
