Put on your party hats and join our editorial team (fig. 1) in celebration: this year marks the 100th anniversary of the Journal of Helminthology (JHL)! The first volume of the JHL appeared in March 1923, immediately setting the tone for the breadth of parasitological research that would fill its pages in the following years. This first issue included articles on the morphology and life history of the nematode Ascaris columnaris, parasitic in North American skunks; a description of the lung fluke Paragonimus compactus; a study of the development and infectivity of larval stages of the sheep hookworm Bunostomum trigonocephalum; and a survey of helminth diversity in the wild birds and mammals of British Guiana (now Guyana). From these beginnings, and despite slowing down through the Second World War, the JHL has continued to publish excellent research for a century, making it one of the oldest journals covering parasitological research.

Today, the JHL exists in a very different format to that of 100 years ago, having evolved along with the rest of the scientific publishing industry. No longer printed on paper and published as regular issues, the JHL is now online only, with articles published continuously and in their final form shortly after acceptance. These changes have not come at the expense of scientific excellence, as the JHL continues to be a key outlet for quality research from around the world in all areas of helminthological research. The JHL's solid international reputation and our continued efforts to publish important and original research findings have set the stage for another century of success.

To celebrate the JHL's milestone, we will be publishing a series of invited Centenary Reviews throughout the year. The first of these, co-authored by Neil Morley and former Editor-in-Chief John Lewis, provides a fascinating overview of the JHL's history over its first 100 years. Other reviews will follow in the coming weeks and months, on topics spanning the range of subjects covered in the JHL and by parasitology more generally. We hope all our readers will enjoy these articles and all other papers we publish, in this special year and in years to come.
