#PreprintAdvent
9. The adoption of preprints in the life sciences is continuing to increase:

*Preprints are currently ~12% of the biomed literature.
*There are >750,000 life science preprints
*There are >50 preprint review services

21. Did you know there's an best time to post a preprint?

It isn't at the time of journal submission, as most do. It's ~1 month prior to journal submission. This allows you to get feedback & rack up views/metrics before submitting.

Exploding, Impacting: looking at bioRxiv preprint view dynamics with R – quantixed
One of the joys of posting a preprint is seeing that people are viewing, downloading and (hopefully) reading your paper. On bioRxiv you can check out the statistics for your paper in the metrics tab.

Preprinting represents perhaps the best route forward for meaningfully improving traditional publishing. But they have even greater potential in significantly altering academic culture, research assessment and trust in research!

14. There are huge benefits to converting your current journal clubs into preprint review clubs.

*Share usable feedback and improve science
*Help ECRs build a public track record
*Actual training

You could post the reviews to @prereview.bsky.social too!

Journal clubs 2.0: An update for the 21st century
Do you run a journal club? The non-profit, scientist-driven ASAPbio (Accelerating Science and Publication in Biology) promotes transparency and innovation in life science communication, and they are offering funding to organise preprint review clubs. Find out about their other activities, too.

This is brilliant!

I've been posting preprint-related advents each day here but have been inspired to put them together into their own site too.

16. Preprints have the potential to enhance your CV.

You evidence your productivity, show wider writing skills via @prelights.bsky.social & reviewing w/ @prereview.bsky.social

Preprints fuel community-focussed infrastructure.

19. Where you post a preprint really does matter.

Preprints posted to bioRxiv receive more citations & total downloads/views than preprints posted to servers owned by traditional publishers.

1. Posting a preprint gives you a citation advantage.

Studies consistently show that posting a preprint results in higher citations and attention than not posting a preprint.

23. Publishing is big business, so big it's like xmas everyday. Publishers have profit margins bigger than almost any other company & prioritise this over the actual science and integrity.

22. Preprints are comparable to their peer-reviewed versions. They're as reliable and trustworthy as the peer-reviewed literature is.

Tracking changes between preprint posting and journal publication during a pandemic
During the COVID-19 pandemic, preprints in the biomedical sciences are being posted and accessed at unprecedented rates, but can we trust them? This study reveals that the majority of preprints published within the first 4 months of the pandemic are comparable to their published version.

20. There's a misconception that you can just post any old rubbish to a preprint server. This isn't true. Any reputable server have a range of screening processes in place.

Really interesting discussion about #Preprints👇

(also follow @jacoates.bsky.social festive #PreprintAdvent 🧑‍🎄🎅🔔)
Great point here. I don't think we'll be able to change the word at this point but this is a growing problem. As I constantly say, most preprints have been peer reviewed as (I'd suspect, based on my experience) most authors share them with colleagues prior to posting.
I'm all for the early sharing of research, but the only meaningful definition of 'preprint' is in the negative -- i.e., an article that hasn't been formally peer reviewed/published. The problem is this definition doesn't describe any evaluative process the work has undergone to get to that stage.

4. There's an entire podcast dedicated to preprints and preprint-related discussions.

15. Preprints are accepted for many Fellowship applications & can help you secure fellowships and jobs.

For example, the Gates Foundation require all grantees to post & use preprints.

As we're all opening our advent calendars every day this month, I thought I'd do a new series sharing 1 preprint-related fact everyday. Could be a reason to post a preprint, combatting a myth or a fact. You'll just have to follow along 😀

6. Posting preprints actually protects you from scooping & enables you to establish priority.

In fact, an increasing number of journals recognise preprints for priority claims & in anti-scooping policies.

The evaluation of preprints is still relatively low; around 2% of preprints are evaluated in a journal-independent manner.

But thanks to great efforts from @prereview.bsky.social and others this is slowly changing.

2. Preprints have been around longer than you may think! Early attempts date back to around the 1940's but technically, publishing before the 21st century is akin to preprinting.

8. Posting a preprint does not prevent publishing in a journal. >90% of journals accept preprints, many publishers own preprint servers & editors actively search servers to invite submissions!

#PreprintAdvent
Peer review and preprint policies are unclear at most major journals
Clear and findable publishing policies are important for authors to choose appropriate journals for publication. We investigated the clarity of policies of 171 major academic journals across disciplines regarding peer review and preprinting. 31.6% of journals surveyed do not provide information on the type of peer review they use. Information on whether preprints can be posted or not is unclear in 39.2% of journals. 58.5% of journals offer no clear information on whether reviewer identities are revealed to authors. Around 75% of journals have no clear policy on co-reviewing, citation of preprints, and publication of reviewer identities. Information regarding practices of open peer review is even more scarce, with <20% of journals providing clear information. Having found a lack of clear information, we conclude by examining the implications this has for researchers (especially early career) and the spread of open research practices.

Preprint adoption differs across fields*. Neuroscience, Microbiology, Bioinformatics and Cell Biology lead the pack. However, based on recent growth there are likely to be some other fields joining these great adopters!

Preprints help to change academia beyond just publishing! They're great for expanding what counts as an output, what kind of things can be shared and how we assess trust in research. They also help to shift the culture within academia, away from much of the toxicity.
