The COVID-19 pandemic is worrying and unsettling for us all. While we are striving to keep any disruption to a minimum, some is almost certainly likely to occur. Referees may need longer to review items, authors may need more time to make revisions, and our editorial team and publishers may also experience delays. All of us are in uncharted waters, but we will do all we can to minimize disruption. Please bear with us, as it may take longer than normal to deal with papers. We will of course be understanding of the difficulties and pressures that everyone faces. To our authors and referees: if you have difficulties meeting a deadline, or if you are facing disruption, please let us know and we will do our best to help in these difficult times.
