According to Wikipedia, Encyclopedia is a reference work or compendium providing summaries of knowledge either from all branches or from a particular field or discipline

According to Collins Dictionary, an encyclopedia is a book or set of books in which facts about many different subjects, or one particular subject are arranged for reference, usually in alphabetical order

^[1]. Ideally the authors are experts with profound understanding of the topics and peer reviewed. We planned to launch a scholarly online encyclopedia 10 years ago where scholars and experts with their identities verified and registered in our sciprofiles.com take the responsibilities as authors to write the entries and the papers are reviewed and quality controlled by peers. For scholars, this encyclopedia will be complementary to the very successful Wikipedia. Now we are ready to start.

. Ideally, the authors are experts with a profound understanding of the topics and the entries are peer-reviewed. In the era of the Internet, people want to learn quickly about current hot topics (e.g., coronavirus, Zika virus, US elections, etc.). However, in the absence of reliable and trusted sources, sensational information spreads faster on social media than verified information and creates so-called fake news. Ten years ago, we planned to launch a scholarly online encyclopedia for which scholars and experts, whose identities would be registered and verified on our platform, sciprofiles.com, would take the responsibility as authors to write the entries, the content would be reviewed and the quality would be controlled by peers and experts in the related field. In 2018, we launched a collaborative content platform, Encyclopedia, at www.encyclopedia.pub for the use of the scholarly community [2].

Here, we announce the launch of Encyclopedia (ISSN 2309-3366), the multidisciplinary open access journal that records high-quality expert entries in all research fields, in a formal, encyclopedia format. All submitted entries will be peer-reviewed before publication online. The Encyclopedia journal will publish the final version of all original entries in an official way, with a DOI. It will provide benchmark information for researchers, as well as the general public interested in accurate and trusted information on specific topics.

Entries published in the Encyclopedia journal are not required to exhibit high novelty or innovativeness, but should be significant to the field and scientifically sound, citing established results, achievements and reliable sources. Papers should be specific to a certain topic, including, but not limited to, a research topic, a definition or introduction to a scientific concept, a hypothesis, a protocol, a biography of scholars or history of research institutes or universities, or interesting videos/images.

, or directly from regular submissions to the Encyclopedia journal. For well-prepared entries on the Encyclopedia platform encyclopedia.pub, authors could apply for publication with an official DOI in the Encyclopedia journal once they have received more than two comments from other scholars to support the publication. The final decision on the Encyclopedia journal would be based on all comments from both open peer-reviewing on the platform and single-blind peer-reviewing moderated by our in-house editors.

We encourage authors to either create entries at encyclopedia.pub or submit the paper in its final version in encyclopedia style to this journal directly on topics in which they have knowledge and expertise. Authors may also edit the entry content based on their published papers according to the requirement of an encyclopedia article. Unlike a review paper or research article, there is no request on the novelty or innovativeness on entries published in the Encyclopedia journal. Instead, all entries published here should be significant to the field and scientifically sound and mature results and achievements. Entry papers should be specific on a certain topic which includes but is not limited to: the research topic, definition or introduction to a scientific concept, hypothesis, protocol, biography for scholars/research institutes or universities, or interesting videos/images. Furthermore, we will also release our Encyclopedia printed volumes in future once there are enough entries on a topic or field.
