The Transactions of the London Mathematical Society has received a 2-year Journal Impact Factor of 0.8 and a 5-year Journal Impact Factor of 0.8 in the Journals Citation Reports for 2022 released by Clarivate on 28 June 2023.
The 2-year Journal Impact Factor is the average number of citations in 2022 to papers published in 2020 and 2021. The 5-year Journal Impact Factor is the average number of citations in 2022 to papers published in the years 2017–2021. For the first time, impact factors are reported only to one decimal place.
The Transactions was founded in 2014 by the London Mathematical Society as a fully Open Access journal and has an eminent Editorial Board with worldwide coverage. It publishes articles of the highest quality across the full range of mathematics, with an emphasis on excellent exposition of research which explores the interconnectedness of pure mathematics or extends the boundaries of its applicability. The Transactions welcomes high-quality submissions.
The journal impact factor is only one amongst a variety of publication metrics. The Transactions has a Journal Citation Indicator of 0.59 and a CiteScore of 0.5. As an early signatory of the Declaration on Research Assessment (DORA), the LMS discourages any use of journal metrics as an indicator of the quality of individual articles or, by extension, of the academic standing of their authors or those authors' institutions.
