Oxford University Press and The Crustacean Society have recently made the decision to convert Journal of Crustacean Biology to an online-only publication from the start of 2021. We have taken this decision in the light of the extensive online usage of the journal and that fact that we are now supplying few print subscribers with copies of the journal. The online journal, which is now considered the version of record, provides enhanced functionality, much of which cannot be offered in the print environment. This includes access to the most current versions of articles at all times; immediate access to the most recently published content via Advance Access; access to further digital content, such as supplementary data, enhanced figure display, reference linking, and other article-level metrics. Thousands of libraries and individuals around the world access JCB online. Readers are able to access a more flexible, modern user interface, which has driven readership increasingly online over the past few years. Finally, a move to online only publication is more environmentally friendly, eliminating the need for paper, shipping materials, and transportation, thus significantly reducing the journal’s carbon footprint. Published content is available to readers instantly upon the day of publication, rather than after a delay as the content is assigned to issue, prepared for print, and dispatched.
