… to remove all barriers in the way of science

Sci-hub mirror, the first pirate website in the world to provide mass and public access to tens of millions of research papers.

A research paper is a special publication written by scientists to be read by other researchers. Papers are primary sources necessary for research – for example, they contain detailed description of new results and experiments.

At this time the widest possible distribution of research papers, as well as of other scientific or educational sources, is artificially restricted by copyright laws. Such laws effectively slow down the development of science in human society. The Sci-Hub project, running from 5th September 2011, is challenging the status quo. At the moment, Sci-Hub provides access to hundreds of thousands research papers every day, effectively bypassing any paywalls and restrictions.

Sci-Hub Ideas

Knowledge to all.

We fight inequality in knowledge access across the world. The scientific knowledge should be available for every person regardless of their income, social status, geographical location and etc.

Our mission is to remove any barrier which impeding the widest possible distribution of knowledge in human society!

No Copyright

We advocate for cancellation of intellectual property , or copyright laws, for scientific and educational resources.

Copyright laws render the operation of most online libraries illegal. Hence many people are deprived from knowledge, while at the same time allowing rightholders to have a huge benefits from this. The copyright fosters increase of both informational and economical inequality.

Open Access

The Sci-Hub project supports Open Access movement in science. Research should be published in open access, i.e. be free to read.

The Open Access is a new and advanced form of scientific communication, which is going to replace outdated subscription models. We stand against unfair gain that publishers collect by creating limits to knowledge distribution.

How To Download Research Papers For Free: Sci-hub, LibGen, etc.

One of the biggest problems about accessing research papers is the cost. At times, you may have encountered the right papers for your research, only to be frustrated that it needs to be paid for. 

There are many ways to download research papers for free, using websites like Oa.mg, LibGen, and more. This post will talk about these platforms, so you can go try it out yourself.

Open Access vs Paywalled Research Papers

There may be many research papers around, but there are some that remain behind paywalls. While the demand for open access to research is undeniable, certain factors contribute to the persistence of paywalled content.

Publishing Companies Need The Funds

Publishers like Elsevier and Wiley operate on a model where subscription fees and paywalls helps to pay for costs such as:

• peer review,
• typesetting, and
• maintaining digital platforms.

This economic structure ensures the sustainability of publishing houses but limits access to those without the means to pay. 

Protect Copyright Laws

Copyright laws further entrench the paywall system. Publishers hold the rights to the vast majority of journal articles, making it illegal to distribute copyrighted material without consent.

This legal framework underpins the operation of paywalls, despite the ethical debate surrounding access to publicly funded research.

In response, platforms like PaperPanda and Unpaywall have emerged, utilizing clever logic and browser extensions to find open access versions of papers, leveraging repositories like the Directory of Open Access Journals.

Paid Papers Seem To Have Higher Value

The perceived value of peer-reviewed journal articles also plays a role. Academic institutions and researchers place high regard on published work, often equating it with career advancement and credibility.

This prestige associated with peer-reviewed publications incentivizes researchers to publish in traditional journals, despite their papers going to be behind a paywall.

Open access platforms and repositories strive to balance this by offering peer-reviewed articles for free, challenging the traditional valuation of scholarly work.

Despite these challenges, the landscape is shifting. Open access initiatives are gaining traction, challenging the traditional publishing model and advocating for free access to research.

As the academic community and the public demand more equitable access to knowledge, the future might see a paradigm shift towards a more open and accessible repository of human understanding.

Best Websites To Download Research Papers For Free

If you are looking to dive into the vast ocean of academic knowledge without hitting a paywall, certain websites are akin to hidden treasures.

These platforms offer free access to millions of research papers and journal articles, covering various areas of science and beyond.

Often dubbed as the “Pirate Bay” of scientific articles, Sci-Hub breaks down the barriers to knowledge by providing free access to research papers that are otherwise locked behind paywalls.

Founded by Alexandra Elbakyan in 2011, this website uses donated institutional logins to bypass publisher restrictions, offering a direct download button for the paper you’re after.

It’s a controversial but popular choice to download papers, with a repository that includes articles from nearly every field of research. Users simply need to find the DOI (Digital Object Identifier) of the paper they want, and Sci-Hub does the rest.

Library Genesis (LibGen)

This is more than just a repository for scientific papers; it’s a comprehensive database of:

• academic books,
• comics, and

Library Genesis offers a wide range of academic and non-academic content, making it a versatile resource for researchers, students, and the general public alike. 

The platform operates on the principle of sharing knowledge freely, and you can easily find and download PDFs of the research papers you need.

This is a free browser extension for Chrome and Firefox that provides legal access to millions of open access research papers.

When you stumble upon a paper online, Unpaywall’s clever logic checks various open access repositories and finds you a legal, freely available copy. 

It’s like having a digital detective at your disposal, dedicated to finding open-access versions of paywalled articles.

Directory of Open Access Journals (DOAJ)

The DOAJ is an online directory that indexes and provides access to high-quality, open access, peer-reviewed journals.

It covers all subjects and languages, making it an invaluable tool for researchers worldwide.

The directory is meticulously curated, ensuring that all listed journals adhere to a stringent open access policy. For those seeking reputable sources, this is a go-to place to find open access research papers across disciplines.

OA.mg is a tool designed to facilitate free access to scientific papers that are otherwise behind paywalls.

Sci-Hub is the most controversial project in today science. The goal of Sci-Hub is to provide free and unrestricted access to all scientific knowledge ever published in journal or book form.

Today the circulation of knowledge in science is restricted by high prices. Many students and researchers cannot afford academic journals and books that are locked behind paywalls. Sci-Hub emerged in 2011 to tackle this problem. Since then, the website has revolutionized the way science is being done.

Sci-Hub is helping millions of students and researchers, medical professionals, journalists and curious people in all countries to unlock access to knowledge. The mission of Sci-Hub is to fight every obstacle that prevents open access to knowledge: be it legal, technical or otherwise.

Download Research Papers and Scientific Articles for free (Sci-Hub and Library Genesis links updated September 2025)

Many students and researchers need to find a paper for their research, to complete the review of an article, or while writing their thesis. Many papers can be found through your university library, but for those that you may not have access to through your institution, we take a look at the three largest open access sites, as well as sci hub and Library Genesis .

Unpaywall Unpaywall is a website built by Impactstory, a nonprofit working to make science more open and reusable online. They are supported by grants from the National Science Foundation and the Alfred P. Sloan Foundation. What they do is gather all the articles they can from all the open-access repositories on the internet. These are papers that have been provided by the authors or publishers for free, and thus Unpaywall is completely legal. They say they have about 50-85% of all scientific articles available in their archive. Works with Chrome or Firefox.

PaperPanda PaperPanda is a free browser extension for Chrome that gives you one-click access to papers and journal articles. When you find a paper on the publisher’s site, just click the PaperPanda icon and the panda goes and finds the PDF for you.

Open Access Button The Open Access Button  does something very similar to Unpaywall, with some major differences. They search thousands of public repositories, and if the article is not in any of them they send a request to the author to make the paper publicly available with them. The more people try to find an article through them, the more requests an author gets. You can search for articles/papers directly from their page, or download their browser extension.

Library Genesis Library Genesis is a database of over 5 million (yes, million) free papers, articles, entire journals, and non-fiction books. They also have comics, fiction books, and books in many non-english languages. They are also known as LibGen or Genesis Library. Many of the papers on Library Genesis are the same as sci hub, but what sets them apart is that Library Genesis has books as well.

OAmg OAmg lets you search for journal articles and papers, download them, and of course cite them in your Citationsy projects. After entering a query it searches through all published papers in the world and shows you the matches. You can then click a result to see more details and read a summary. It will also let you download the paper through a couple different, completely legal open access services. www.oa.mg

Sci-Hub (link updated September 2024) Finally, there’s Sci Hub . Science-Hub works in a completely different way than the other two: researchers, students, and other academics donate their institutional login to Schi-Hub, and when you search for a paper they download it through that account. After the articles has been downloaded they store a copy of it on their own servers. You can basically download 99% of all scientific articles and papers on SciHub. Just enter the DOI to download the papers you need for free from scihub. Shihub was launched by the researcher Alexandra Elbakyan in 2011 with the goal of providing free access to research to everyone, not only those who have the money to pay for journals. Many in the scientific community praise hub-sci / sciencehub for furthering the knowledge of humankind and helping academics from all over the world. shi hub has been sued many times by publishers like Elsevier but it is still accessible, for example by using a sci hub proxy.

You can find links to Sci-Hub on Wikipedia ( https://en.wikipedia.org/wiki/Sci-Hub ) or WikiData ( https://www.wikidata.org/wiki/Q21980377#P856 ).

How to use Sci-hub to get academic papers for free

• Post author: Emil O. W. Kirkegaard
• Post published: 10. April 2018
• Post category: Science

I regularly tell people on Twitter to use Sci-hub when they say they can’t access papers:

Yes you can, use Sci hub like normal people do. — Emil O W Kirkegaard (@KirkegaardEmil) April 10, 2018

However, it seems that people don’t really know how to use Sci-hub. So here is a simple, visual guide.

1. Go to the Sci-hub website

The URL may change to the website because the lobbyists of Big Publish (Elsevier, SAGE etc.) constantly try to get government to censor the website as it cuts into their rent-seeking profits . You can find the latest URLs via this handy website called Where is Sci-Hub now? (alternatively, via Wikipedia ). Currently, some working URLs are:

• https://sci.hubg.org/
• https://sci-hub.yncjkj.com (global)
• https://sci-hub.mksa.top/ (global)
• https://sci-hub.it.nf/
• https://sci-hub.st/ ( São Tomé and Príncipe )
• https://sci-hub.do (Dominican Republic)
• https://sci-hub.se/ (Sweden)
• https://sci-hub.shop (global) [redirects]
• https://scihub.bban.top (global) [redirects]
• https://scihub.wikicn.top/ (global) [redirects]
• https://sci-hub.pl/ (Poland)
• https://sci-hub.tw (Taiwan)
• https://sci-hub.si (Slovenia)
• https://mg.scihub.ltd/ (global)

If your country blocks the website, use one of the many free general purpose proxies. I tested hide.me for the purpose of writing this article and it works fine for Sci-hub using the Netherlands exit.

2. Go to the journal publisher’s website

Go to the website of whatever article it is you are trying to get. Here we pretend you want the article in my tweet above:

• Seeber, M., Cattaneo, M., Meoli, M., & Malighetti, P. (2017). Self-citations as strategic response to the use of metrics for career decisions . Research Policy.

The website for this is sciencedirect.com which is Elsevier’s cover name. Then, you locate either the URL for this (i.e. https://www.sciencedirect.com/science/article/pii/S004873331730210X) or the article’s DOI. The DOI is that unique document identifier that begins with “10.”. It is almost always shown somewhere on the site, so you can use search “10.” to find it. In rare cases, it is in the page’s source code or may not exist. If it doesn’t exist, it means you usually can’t get the article thru Sci-hub. When you have the article’s URL/DOI, you simply paste this into the Sci-hub search box. Like this:

Then you click “open” and you should get something like this:

In some cases, this may not work. The APA journals seem to cause issues using the URL approach, so use the DOI approach. Sometimes Sci-hub returns the wrong article (<1% I should guess).

Finding articles from APA journals

These journals refuse to give a DOI and they don’t work with URL either usually. Example this paper . A workaround is to search Crossref for the title which gives the DOI, then use the DOI to fetch the paper as usual:

• Directory of Open Access Journals ( DOAJ ): A community-curated online directory that indexes high-quality, open-access, peer-reviewed journals.
• arXiv: A repository of electronic preprints for physics, mathematics, computer science, and related fields.
• CORE: The world’s largest collection of open-access research papers.

Pro tip: Many of these databases offer email alerts for new papers in your area of interest, helping you stay up-to-date with the latest research.

2. Utilize Academic Search Engines

Specialized academic search engines can help you find both open-access and potentially accessible papers:

• Google Scholar: The most popular academic search engine, with features like cited by and related articles.
• Microsoft Academic: A free public web search engine for academic publications and literature.
• Semantic Scholar: An AI-powered research tool for scientific literature.

These search engines often provide direct links to free full-text versions when available or point you towards institutional repositories.

3. Explore Institutional Repositories

Many universities and research institutions maintain their own repositories of scholarly work produced by their faculty and students. These repositories often make papers freely available to the public. Try searching for “[University Name] repository” to find these goldmines of information.

4. Check Author’s Websites and Social Media

Many researchers maintain personal websites or profiles on academic social networks where they share their work. Try searching for the author’s name followed by their institution or area of expertise. Platforms to check include:

• ResearchGate
• Academia.edu

5. Contact the Authors Directly

If you can’t find a free version of a paper, don’t hesitate to reach out to the authors. Most researchers are happy to share their work and may send you a copy of their paper. Look for the corresponding author’s email address in the paper’s abstract or contact information.

6. Use Browser Extensions

Several browser extensions can help you find free versions of paywalled articles:

• Unpaywall: A legal and simple tool that searches for free versions of scholarly articles.
• Open Access Button: Searches for free, legal copies of research papers.
• Kopernio: Helps you access PDF versions of scientific articles.

7. Take Advantage of Preprint Servers

Preprint servers host early versions of research papers before they undergo peer review. While these papers should be approached with caution, they can be valuable sources of cutting-edge research:

• bioRxiv: For life sciences
• chemRxiv: For chemistry and related fields
• SocArXiv: For social sciences

8. Utilize Your Library’s Resources

Don’t forget about your local library! Many public and university libraries offer:

• Access to academic databases
• Interlibrary loan services
• Remote access to digital resources

Even if you’re not currently a student, some libraries offer cards to community members that include database access.

9. Explore Sci-Hub Alternatives

While Sci-Hub is popular, it operates in a legal grey area. Instead, consider these alternatives:

• Open Access Button: A legal tool that helps you request access to research papers.
• Lazy Scholar: A browser extension that finds free full-text PDF versions of articles.
• Unpaywall: Another legal alternative that finds open-access versions of articles.

10. Stay Informed About Open Access Initiatives

Keep an eye on developments in the open access movement. Initiatives like Plan S are working to make all publicly funded research freely available. Following these developments can help you stay ahead of the curve in accessing free research.

Ethical Considerations and Best Practices

While accessing free research papers, it’s crucial to keep these ethical considerations in mind:

• Respect copyright laws and publisher agreements.
• Use obtained papers for personal research and educational purposes only.
• Properly cite all sources in your work.
• Support open access initiatives when possible.

Accessing research papers for free is not only possible but also increasingly important in our interconnected world. By utilizing the methods outlined in this guide, you can tap into a vast wealth of knowledge without breaking the bank. Remember to always respect copyright laws and support the open access movement to ensure that knowledge remains freely accessible to all.

Product manufacturing quality is influenced by various factors of the production process, so the key to improve product manufacturing quality is improving the relevant parameters and processing methods in the manufacturing process. Aiming at this issue, a manufacturing quality improvement method of using gene recombination and editing mechanism is proposed. In this method, an optimization model is established and described by formulas, in which three optimization objectives including production quality, costs and time are involved. In the model, the quality indicator is measured by a comprehensive evaluation approach of product gene. To address the model, an improved genetic algorithm (GA) and artificial bee colony algorithm (ABC) with hybrid encoding scheme (H-IGA-IABC) is designed by considering the different types of gene elements. 15 comparison experiments with different scales are performed to test the model and H-IGA-IABC. In these experiments, H-IGA-IABC, IGA, IABC, general GA (GGA) and general ABC (GABC) are involved. According to the data obtained by different components and algorithms, the search ability, speed of convergence of H-IGA-IABC are better than that of other components and algorithms, especially in solving large-scale problems. Besides, IGA and IABC (Two components in H-IGA-IABC) also perform better than GGA and GABC in those experiments. Compared with the solution before optimization, the quality evaluation results and other indicators of the solutions after optimization are significantly better. Therefore, the proposed product quality improvement method is effective and performs well.

Keywords: Manufacturing quality improvement, Product gene evaluation, Multi-objective optimization, Improved genetic algorithm and artificial bee colony algorithm, Hybrid encoding scheme
