Language Problems and Language Planning (LPLP) is a multilingual journal created in 1969. It focuses on language issues and the challenges they raise for social life, with an emphasis on how these issues are addressed and processed through language policies.

LPLP cultivates a strongly interdisciplinary spirit, publishing the works of researchers from several disciplinary backgrounds that contextualise and analyse the ways in which language functions in society, particularly as an object of regulation, management and contestation. While case studies of particular national or regional issues are welcome, preference is given to work offering generalisable insights of relevance across diverse contexts, with attention to language and communication amid globalisation, particularly from a language policy perspective. Given the journal’s interdisciplinary scope, authors are requested to explain their findings in a way that is accessible to curious scholars from any discipline in the social sciences and humanities.

LPLP also regularly publishes contributions devoted to interlinguistics which analyse the development and use of planned languages. Articles and book reviews on such topics have explored, for instance, the links between religion and language planning, the use of digital media in the making of the transnational Esperanto community and Slavic constructed languages on the internet.

The journal is published both online and in print in collaboration with John Benjamins Publishing Company. It publishes three issues per year and is listed in Scopus under three subject areas: Linguistics and Language; Sociology and Political Science; Communication.
