brief intro on preprints

Preprints are not peer-reviewed scientific articles, posted before publication in scientific journal. Currently, the most popular form of preprint circulation relies on public preprint servers, specific for area of science (medRxiv for health sciences, PsyArXiv for psychology, etc.).

Details of preprint submission differ between servers and fields:
- Preprint can be posted after acceptance by journal, but still before publication. In this manner, scientists provide free version of their work in accordance with green open access. Some journals provide similar service by themselves ("issue in progress", "advance articles" etc.), and many researchers use personal websites for storing their work, but preprint servers are still easier to follow.
- Preprints are often posted during formal peer-review, after or along with submission to a journal. Authors can receive more opinions on their reporting of research, for instance by discussions on Twitter or platforms specifically built for public peer-review.
- Preprints can be posted before engaging with journals. In addition to the advantages mentioned above, some publishers employ editors who pick interesting preprints and invite their authors to the peer-review process. Moreover, there are fields where journal publication can be unnecessary (an example is mathematics: work of G. Perelman presented only in preprints was awarded Fields medal).

Preprints are also used to speed up the circulation of scientific information. Depending on the field, rapid information exchange can aid crisis situations (recent example: Zika), a proliferation of new technologies, scientific disputes, or simply shorten waiting time for getting out the results. Preprints also support scientists on the individual level, as those works can be earlier listed in funding proposals or career summaries.

Knowledge Browser at this moment indexes preprints from the following servers: arXiv (physics, mathematics, and other quantitative sciences), bioRxiv (biology), chemRxiv (chemistry), NEP RePEc (economy and politics), AgriXiv (agriculture), BodoArXiv (medieval studies), EarthArXiv (planetary sciences), EcoEvoRxiv (ecology and evolution), ECSarXiv (electrochemistry), engrXiv (engineering), LawArXiv (law research), MarXiv (marine sciences), MediArXiv (media research), MetaArXiv (meta-research), MindRxiv (health sciences), NutriXiv (nutritional sciences), PaleorXiv (paleontology), PsyArXiv (psychology), SocArXiv (sociology), SportRxiv (health sciences), LIS Scholarship Archive (all sciences), medRxiv (health sciences), PeerJ Preprints (biology), Preprints.org (all sciences), viXra (all sciences), ESSOAr (planetary and space sciences), PhilSci (philosophy), NBER (economy and politics).
