The International Standard Book Number (ISBN) is an identification code for a published book/textual work.
The ISBN is assigned by the International ISBN Agency, an international body based in London.
In Indonesia, the National Library of Indonesia (Perpusnas) has a quota of 1 million ISBN numbers for publishers intending to publish printed books, educational films/videos, audiobooks, electronic publications, or mixed media publications containing text.
"The development of publishers and publications in Indonesia can be seen from the usage of ISBNs allocated to Indonesia," said Perpusnas on its website.
Based on Perpusnas data, the trend of ISBN issuance domestically increased continuously from 2015 to 2021. However, the number decreased in 2022.
ISBN issuance then started to rise again in 2023 and continued until 2024, although it has not reached the high levels of 2019-2021 as shown in the graph.
Perpusnas assesses that the use of ISBNs still has the potential to increase in the future.
"The development of ISBN usage in Indonesia is predicted to always increase due to the emergence of several policies issued by each ministry/agency, as well as higher education institutions that require the creation of written works," said Perpusnas on its website.
"Similarly, the national reading and literacy improvement program will significantly impact the level of ISBN demand," it continued.
