In 2021, the mission of Pediatric Neurology Briefs (PNB) remains the same: “PNB is a continuing education service designed to expedite and facilitate the review of current scientific research and advances in child neurology and related subjects.” PNB has been published since 1987 and consists of 34 volumes with greater than 3700 articles and includes over 10,000 citations referencing the works of approximately 28,000 scholarly authors. PNB was relaunched as an open access, peer-reviewed journal with an expanded editorial board in January 2015. In 2018, the publishing model of PNB evolved even further. The canonical version of the article was published online as soon as it was accepted and typeset. The published articles are collected into online volumes, and an annual collection for print will be available at the end of every year.

The Editors of PNB select source articles using criteria that include recent publication in a peer-reviewed journal and a topic of clinical value to practicing pediatric neurologists. Contributing Editors provide detailed summaries of published articles, followed by commentaries based on their experience and corroborated by appropriate supplementary citations. In 2015, PNB launched a new website and content management system capable of organizing peer-review and providing improved indexing, DOI assignment, and online full-text article view. Before the internet, the Editor periodically compiled and published the PNB articles in book form with index, according to subject heading and chronological order [1 - 3].

In 2016, digitization of the 30 years of back issues was completed. There are now over 3700 full-text open access articles available on the journal website. Also, in 2016, PNB was selected for inclusion in PubMed Central® (PMC). PMC is a free archive of biomedical and life sciences journal literature at the U.S. National Institutes of Health's National Library of Medicine (NIH/NLM). The most highly accessed articles published in 2020 covered topics related to new epilepsy treatment [4], mechanism of the ketogenic diet [5], and genetic diagnosis [6].

Despite the immense personal and professional demands of the global COVID-19 pandemic, PNB published an increased number of manuscripts this year. The annual collection organizes the articles under 17 different sections and is available for download in PDF format here: Pediatric Neurology Briefs - Vol. 34 - 2020.
