Established in 1970, Congressus Numerantium is one of the oldest international journals with a focus on publishing high-quality papers in combinatorics and related areas. Over the years, it has published numerous fully refereed regular papers and conference proceedings for many prestigious conferences. However, publication was temporarily paused on January 15, 2020. Throughout its active years, Congressus Numerantium adopted a print format, following a subscription-based model for readers and releasing 234 Volumes. Despite the changing landscape of academic publishing, Congressus Numerantium demonstrated resilience. In 2024, the journal embarked on a transformative journey, reemerging in both print and online formats with the objective of publishing 2 volumes annually, scheduled for release in June and December. We cordially invite original research papers and survey articles, welcoming significant contributions to both the pure and applied aspects of combinatorics. Furthermore, we extend a warm invitation for special issues dedicated to conferences and workshops in combinatorics and related fields, carrying forward the rich tradition of this esteemed journal. Special issues on selected topics of current interest to the community of combinatorics are also welcome.
