A preprint (submitted version) is the version of an article that is ready to be submitted to a publisher but has not yet undergone peer review. Since the publication process is often slow, sharing preprints has become important for faster research visibility and dissemination. The intention is to receive early feedback from other researchers, speed up the formation of possible collaborations, and make research more transparent.
For sharing preprints, many preprint servers are available. Sharing preprints is free, and most servers assign the preprint a permanent identifier, such as a DOI, so it can be cited. Many journals allow citation of preprints in the same way as peer-reviewed articles.
Sharing preprints is especially important in natural sciences, technology, and economics, but in recent years, its popularity has increased also in psychology, social sciences, and humanities.
Please note:
Sharing preprints is encouraged by many funders but usually does not alone meet their OA requirements. Note that preprints are also not considered OA under the Ministry of Education and Culture's current funding model, as a preprint is not peer-reviewed.

When choosing a preprint server, primarily consider to whom the article is directed and ensure the server has good service levels. The following features characterize reliable preprint servers:
Permanent identifiers, e.g., DOI (the preprint can thus be cited)
Quality control (e.g., plagiarism check)
Guarantee of long-term server availability (good archiving policy)
Open licensing (Creative Commons)
Indexing in search engines (e.g., Google Scholar)
Versioning (when uploading an updated version, it links to the previous version)
