In the name of science and free access to scientific articles we need to use, I've got a list of two free tools to help you download the full and free versions of full scientific articles. Web browser extensions ---------------------- Method 1: Unpaywall - Unpaywall is a free browser extension that will check to see if it can find a free article of the version you're currently reading. Simple as that. It will have a little green popup in the right hand corner you can click on if you come across this article. https://unpaywall.org/ Open Access Button - Claims to open up locked articled. Have not tried it myself. https://chrome.google.com/webstore/detail/open-access-button/gknkbkaapnhpmkcgkmdekdffgcddoiel CORE Discovery - Again, claims to beat the paywall and access the article. May just be quering Sci-Hub https://chrome.google.com/webstore/detail/core-discovery/ockidfiihjhkngdalfnbeeepgfbmkmlh?hl=en These will occasionally work. Method 2: Sci-Hub - Sci-Hub is a full free (and pirated) method to find journal articles you're looking for. Generally, just paste the full link of the journal article that's restricted. It will almost fine all articles 100% of the time if you just know how to paste in the URL properly. It generally works really well if you use a DOI (Digital object identifier) url. Here is an example of a DOI url Redirecting. Sci-Hub has to change URLs frequently because of the crackdown on the from the academic industrial complex. Some of the Sci-Hub links aren't working, so you can visit a site that has mirrors of Sci-Hub URLs. It has a small popup on the front page, but if you hit ESC it will go away. Sci-Hub: Removing barriers in the way of Science → Latest Sci Hub links: The best place to find the most up to date and working Sci-hub mirror is Reddit's Sci_Hub section: https://www.reddit.com/r/scihub/ or Alexandra Elbakyan's Twitter: https://twitter.com/ringo_ring Library Genesis has tons of links to articles, ebooks and much much more. Their current URL is https://libgen.li/ However, they also have a Reddit with their most up to date mirrors: https://www.reddit.com/r/libgen/ Zlibrary. Current working URL: https://b-ok.cc/ or https://z-lib.org/ and, of course, they have their own Reddit as well (although it seems to be volunteer manned): https://www.reddit.com/r/zlibrary/ Method 3: #ICanHazPDF - This is kind of the method of last resort and I've never had it work for me, but it's worth a shot. You can post the title of the article along with a URL along with the hashtag #ICanHazPDF and other researchers online will see if they can share it with you. It's worth a try if you can't find it anywhere else. Access Subscription Only Newspapers for Free ------------------------------------------- One other thing I wanted to recently post about is a really awesome website paywall killer browser extension called bypass-paywalls-chrome. Now, unfortunately, this extension requires a little bit of technical knowledge to install, but it's explain very well in the read me a file. Here's an extensive list of all the sites they prevent you from getting the "Sorry, you're not subscribed" error message when trying to access a paywalled website. Bypass the following sites' paywalls with this extension: ByPass Firewalls Chrome INSTRUCTIONS BELOW Adweek Algemeen Dagblad American Banker Baltimore Sun Barron's Bloomberg Quint Bloomberg Brisbane Times Business Insider Caixin Central Western Daily Chemical & Engineering News Chicago Tribune Corriere Della Sera Crain's Chicago Business Daily Press De Groene Amsterdammer De Tijd De Volkskrant DeMorgen Denver Post Dynamed Plus Eindhovens Dagblad El Pais Encyclopedia Britannica Examiner Financial News Financial Times First Things Foreign Policy Fortune Genomeweb Glassdoor Haaretz.co.il Haaretz.com Handelsblatt Harper's Magazine Hartford Courant Harvard Business Review Herald Sun Het Financieel Dagblad History Extra Il Manifesto Inc.com Investors Chronicle L'Écho L.A.

Well, first of all you need an unzip client (one comes with Windows), but you can also use my personal fav, WinRAR or 7Zip. Second, you download the ByPass Firewalls Chrome ZIP file (apparently there is a version for Firefox as well). Since this version is for Chrome, it will work on browsers that use the Chrome engine like Microsoft Edge, Opera, and Brave. Then you unzip it into a folder or your choice and here are the further 3 instructions: 1. In Chrome go to the extensions page (chrome://extensions, or edge://extensions, brave://extensions, opera://extensions, etc). 2. Enable Developer Mode. 3. Drag the bypass-paywalls-chrome-master folder anywhere on the page to import it (do not delete the folder afterwards). And you're done. It works great on sites like the WSJ which are impossible to read without some kind of bypass. Find Old Deleted Web Pages -------------------------- I've found a very new cool extension if you're looking for copies of old web pages that have vanished off the internet and you can't find them. It's very helpful if you know the direct URL of the site and knew it existed in the past but has just vanished completely. The Wayback Machine works for most things, but for forums and other miscellaneous links it isn't so great. This is an extension called Web Archives and you can download the extension here: https://github.com/dessant/web-archives/blob/master/README.md Web Archives is a browser extension which helps you to find archived and cached versions of web pages. Searches can be initiated from the right-click context menu, the browser toolbar, or the address bar in case of a server error. Supported search engines, archive and cache sources: Wayback Machine Google Cache Bing Cache Yandex Cache Archive.is Memento Time Travel WebCite Exalead Cache Gigablast Cache Sogou Snapshot Qihoo 360 Search Snapshot Baidu Snapshot Naver Cache Yahoo Japan Cache Megalodon
