Hello world!

Write a detailed note on Preprints and their servers.
In academic publishing, a preprint is a version of a scholarly or scientific
paper that precedes formal peer review and publication in a peer-reviewed
scholarly or scientific journal. The preprint may be available, often as a non￾typeset version available free, before or after a paper is published in a
journal.
Since 1991, preprints have increasingly been distributed electronically on
the Internet, rather than as paper copies. This has given rise to massive
preprint databases such as arXiv and HAL (open archive) etc. to institutional
repositories. In 2016, several new preprint servers were proposed by council
centre for Open Science and ASAPBIO (Accelerating Science and
publication in biology). In March 2017, the National Institutes for Health
issued a new policy encouraging research preprint submissions.
The immediate distribution of preprints allows authors to receive
early feedback from their peers, which may be helpful in revising and
preparing articles for submission. Preprint are also used to demonstrate the
precedence of the discoveries and a way to protect the intellectual property
(a prompt availability of the discovery can be used to block patenting or
discourage competing parties).
Most publishers allow work to be published to preprint servers before
submission. In academia, preprints are not likely to be weighed heavily when
a scholar is evaluated for tenure or promotion, unless the preprint becomes
the basis for a peer-reviewed publication.
Preprint Servers
In scholarly and academic publishing, preprint servers play a high-level
role. Preprint servers are a simple way for scholars to receive feedback
on their articles quickly. Getting published in a peer-reviewed journal
often takes a long time from the time of initial submission. Editors and
reviewers use the waiting time to evaluate and critique manuscripts, and
authors make the necessary changes. To shorten that waiting time,
scholars submit their unpublished work in the form of preprints. This
allows authors to receive early feedback from their peers, which might
help revise and prepare the submission preprints.

There are preprint servers for many different subjects like:

1. ArXiv: for maths, physics, and other sciences.

2. PeerJ PrePrints: For Biology and Medicine.

3. PsyArXiv: allows publishing preprints in the field of psychology

4. Orvium: a fresh and exciting new preprint server, with a very intuitive

interface and innovative review process that puts the power back in the

author’s hands.

5. ChemRxiv: For chemistry.

5. BioRxiv: a preprint repository for biological sciences

6. SocArXiv: for social sciences.

6. EngrXiv: For Engineering.

5. EcoEvoRxiv: For Ecology, Evolution and Conservation
