How do I do it? jedi tricks, I have ways and means of finding the droids you ARE looking for
Its called sci-hub.
A currently active sci-hub address is sci-hub.tv although I'll check a few others to test they are still up. Don't worry about the security alert, its just due to a self-signed SSL security cert, the creator of sci-hub, a kazakh student probably can't get any central authority to hold an official signed certificate because of the way the place came to be. Basically she got a beehive up her ass about paywalling sons of bitches and closed-access, believes that knowledge ought to be freely disseminated and that the practices of the big publishing houses, in a word, fucking stink. Which they do.
So there have been a fair few domains that have changed from time to time, when the courts succeed in getting one domain shut down, she just creates several more. The publisher Elsevier launched a court battle against her, she lost, but she more or less told them hey, bugger off, you can't extradite me, and there is nothing whatsoever you can actually do to stop me, whether you like it or not, and I don't give a shit what the court rules. Shut down one site, and up pop several more.
Just like Herakles battling the Lernean hydra. Only the courts have no flaming brand with which to cauterize the burnt stumps of individual domain names. The more get felled, the more there are.
Current addresses operational as of wed march 14th 2018:
Sci-hub.tv
http://sci-hub.hk/sci-hub.tw
sci-hub.name
sci-hub.la
If needs be at any time I can always post....somewhere else...to find out whatever the current sci-hub hosts are. There are ways and means, and I reckon that the creatrix of the site is fresh out of tuppeny fucks of which to bestow upon the ladies and gentlemen of the jury and quite obviously has decided any judge can go stick two fingers up their backsides and use their sphincter as a mount for a pogo stick.
And don't worry, its no imposition, you just need the DOI, although SOMETIMES, not always but on occasion a PMID will suffice, usually though you need the DOI number, plug it into the text input bar and click the unlock icon at the end and there you go. Works by spoofing an access token thats normally passed between the publisher's sites and a properly authenticated user, making it appear that its being accessed from a uni, or someone else with a valid login and subscription, then forwarding the results to the sci-hub end user.
Apparently now, even users who have a valid uni institutional access are using sci-hub, in order to bypass the paywalls and the publishing houses, as a protest, to make sure they can't continue profiteering from both researchers, unis and end users, ripping them off the way they have been. Sci-hub is really doing well in sticking it to the bastards.
If you come up against any regional blocks, then you might need to download TORbrowser, its firefox-based and integrates TOR with the browser, and then you can just route the connection through another set of countries, if there are any local connection blocks.
And one other little package of goodies, this one quite definitely does need local court-ordered ISP level blocks walked round in some countries, like the UK. TORbrowser does the job perfectly.
http://gen.lib.rus.ec/This is basically a pirate book site. Its the full scanned and uploaded, downloadable (as .PDF usually) book repository answer to sci-hub's service for for open access journal articles.
You can find an awful lot of useful books, such as by searching using the ISBN number, or the author and title etc; I've had luck finding a book I needed quite a few times, and often there will even be several editions available, since there are currently at the very minimum, 2 million uploads.
