Are books in pdfdrive.com legal or illegal? Is it legal to download books in PDF-format from https://www.pdfdrive.com/ ? How one can verify if the book given in the site is a legal copy or not?
You can't, in general, know whether a distributor of a work has permission to distribute, or is a pirate site. I verified that they have posted an illegal copy of a work that I created, and I know that I did not grant permission to them (or anyone) to infringe my copyright. Both hosting and downloading works without permission is a violation of copyright law, so both parties are liable. Downloaders may erroneously rely on the "I didn't know!" defense, which in the US carries no legal weight. Even so, if you download my book, it will probably cost me vastly more to sue you for infringement than the damages that I might be awarded over your infringement. Usually, copyright holders go after the pirate sites, and only rarely go after particularly egregious serial downloaders.
Everything you see there is copyright and trademark the Tolkien estate or a derivative work thereof. It's all illegal.
It is legal to rewrite a book that is out of copyright, although ethical considerations demand that the original author and source be credited. You need to derive your rewrite from a version that is out of copyright, however, rather than a translation whose incremental innovations due to the transformation arising from the translation is still under copyright. Certainly, the 16th century original would be out of copyright, and in all likelihood, so would many of the later editions, but probably not the one from 1971.
Why would the method by which you transfer a item that has a copyright impact the copyright? You buy a new book at a new bookstore, a used book at a used bookstore, a used book at a garage sale, someone gives you a book, you find a book on the sidewalk, you steal a book from a store, you buy and download an ebook, you give an ebook to someone on a USB stick, you download an ebook via Bittorrent. The author's copyright - as well as the design copyright, and any book company trademarks - does not change in any of those scenarios. Copyright around most of the world - read Berne Convention (Wikipedia) - says that copyright exists at the moment of creation of a work, i.e. a work that you say is "100% yours". This has nothing to do with the way the work may be transmitted or stolen or downloaded. A work in the public domain can still be copyrighted in terms of cover artwork and design, annotations, etc. Read Welcome to the Public Domain - Stanford Copyright and Fair Use Center You can say someone "owns" a book in the sense that they might have paid for it or it is personal property and one could justifiably call it theft if someone took it from them, but "owning" the physical or electronic copy in any sense doesn't mean you own the copyright. Read the copyright notice on a book or ebook; you get a license to read it, not ownership of it. Read What's the difference between Copyright and Licensing? - Open Source Stack Exchange. Sure, the TOS of a network can specify the ownership/licensing status of the files shared on such network. They will almost all explicitly say not to upload or share anything that will violate the copyright of that work. The TOS of a network could possibly say that anything that is uploaded is automatically licensed to them. A network could demand the reassignment of copyright upon upload, but that would have to be outlined in the TOS and is not simple. See Copyright Ownership and Transfers FAQs - Stanford Copyright and Fair Use Center.
If the blog author holds the copyright on the ebook, they can distribute the ebook anyway they choose, either via download from Github or elsewhere, or sell it in an online store. They hold the copyright, they alone can decide how to distribute it. If they also sell the ebook in the Microsoft press Store, they may have an agreement with the store to also allow their own free downloads; it's hard to say without knowing the agreement. If there are ebooks on Githb available for viewing or download, the owner of the Github page should hold copyright of the ebook, both 1) for their own protection against copyright infringement, and 2) to not break GitHub's TOS against copright infringement: https://help.github.com/articles/github-terms-of-service/#f-copyright-infringement-and-dmca-policy
Yes. You can sell it for whatever you can get for it. The license allows you to watch the DVD. If you sell the DVD, you won't be able to watch it - but the buyer will. This is same principle that books are subject to copyright, but there is nothing stopping you selling your books second-hand to a dealer.
First of all derivative works are not exactly "illegal". They are fully legal if the owner of the copyright in the original work has given permission. If no permission has been given, they may be copyright infringements. But they may fall under an exception to copyright. Under US law, the most common exception is "fair use". See this question and answer for more on fair use. But particularly relevant in this case is that a parody is usually a fair use, although as in every fair-use decision, there is pretty much no clear-cut, hard&amp;fast rule on what is and is not fair use. In the UK and much of the EU (or maybe all of it, I am not sure) there is a somewhat similar concept known as "fair dealing". It is also an exception to copyright. So it is possible that such works fall under fair use, fair dealing, or another exception to copyright, or that the rights-holder has given permission. Secondly, copyright infringement is a tort, not a crime, under most circumstances. It is enforced when, and only when, a copyright-holder chooses to take action, sending a take-down notice or copyright complaint, of filing suit for infringement. Some rights-holders choose as a matter of policy not to take such actions, thinking that such derivative works actually benefit them. That is their choice to make. Some rights-holders don't have the time or money to track down and take action against most infringements, and will only act if they think the derivative work will in some way cost them a lot of money or harm their reputation. Some rights-holders may just not have heard, yet, of specific possible infringing derivative works. As for Acta2, it has not yet been approved, the Wikipedia article linked in the questions says: In order for the text of the directive to become law in the EU, it must be approved by the European Council on 9 April 2019 The article also mentions significant continuing opposition. If it is approved, it is not clear, to me at least, how it will affect sites hosting such content, nor how it will interact with the copyright law of individual EU nations. If approved, it will no doubt take some time before enforcement is widespread. And of course it will only apply when EU law applies. If both site and author are outside the EU -- say if both are from the US -- it seems that it could not apply.
A TOS is not intrinsically illegal, but an interpretation of a TOS may or may not be supported by a court, that remains to be seen. It probably does not constitute a &quot;deceptive practice&quot; under FTC standards. The TOS is your permission to use the software, and there can be no question that they have the right to impose conditions on customer use of the software. E.g. Amazon cannot freely use software that is only licensed for free educational use. They speak of &quot;ownership&quot; of IP so created and explicitly disclaim any claims about Current Law in Your Jurisdiction. At the crucial point in the agreement, they switch to talking about the license (BY-NC) that they grant when you are not a paid member. The exact details of this ownership are not part of the free tier TOS, but they do seem to add certain protections to &quot;owned&quot; content created under the Pro plan – they are under no legal obligation to make all content universally visible and usable.
