Legal distribute a book by Isaac Asimov The Last Question by Isaac Asimov, is freely available on the web, albeit not being a free work. This is not unusual, as piracy is quite rampant on the web. What I find unusual is the sources that are offering an apparent pirated copy of the book. For example, the Princeton physics website is a source. According to a website claiming to represent Isaac Asimov's estate: As a result, none of Asimov's fiction is legally available for free download on the net without the permission of his estate. Source How can Princeton University legally distribute the book?
As the quote in your question notes (albeit in contrapositive form), Asimov's fiction may be made legally available for free download on the net with the permission of his estate. It is either that case that Princeton University's physics department (or whatever individual person or agency put up the story online) has obtained permission from Asimov's estate to distribute the story on their website, or they simply distribute it without legal permission, and Asimov's estate has not taken legal action to have it removed, which they may or may not choose to do in the future. Consider also that the Princeton distribution does not appear to have been meant to be in any way public: looking one directory level up (Princeton University Physics 115A and B: Physics for Future Leaders) shows a course overview with syllabus and lecture notes, without any apparent link to the story. Probably, it was put online for use exclusively by students taking that particular class, and the professor(s) just didn't put any controls to stop it from being accessible to anyone who knew the URL. This doesn't really change that fact that its public accessibility is, strictly speaking, copyright infringement, but it may be a favorable factor toward a finding that distribution outside of the class was innocent infringement, which can lessen (or, rarely, nullify) the penalty. (And it may be quite possible that distribution within the class was defensible under fair use/dealing, which considers educational context as a favorable factor.)
In general this kind of brief literary reference is not unlawful, and such things occur in both novels and commercial games with some frequency. Making such a reference a major part of the plot, such as by using a name from a previous work as a major character, particularly if other aspects of that character are also used, is far more likely to cause a problem. In the united-states this would be a matter of fair use. In general, when only a very small part of the source work is used, such a a single name; where the use is &quot;transformative&quot;, that is used for a rather different purpose than in the source work; where the use does not harm the market for the original work; and where the use does not serve as a replacement for the original, it is likely to be held to be fair use. But fair use decisions are always fact-dependent, and are made case-by-case, so it is hard to be absolutely sure of one in advance. But the kind of literary reference described in the question is very unlikely to be held to be copyright infringement.
"Educational use" does not get a free pass on the law against circumventing copy-protection. First, "educational use" is extremely broad and could include "to post on Stackexchange", or "so that I can learn something". The cited clause specifically limits this exception to "A nonprofit library, archives, or educational institution" – the library must be nonprofit, and the archive or educational institution may also need to be nonprofit (until the courts fix the ambiguity in the scope of "nonprofit"). Second, the circumvention has to be very limited: the purpose must be only to evaluate the work, to see if you want to legally acquire it. So a nonprofit library can peek into a work to see if they want to buy a copy, but you may not. The only thing the library can do is evaluate the work for legal acquisition, and they have to get rid of the pirated copy once they've made the decision. Additionally (other parts of the subsection say), they can't do this is there is an equivalent legal copy available (e.g. if there's a print book available, they can't hack into the e-book to "determine" whether they want the book), and w.r.t. libraries and archives they must be open to the public.
Yes, such a site can be created without infringing copyright Facts about the game are facts.They are not protected by copyright. Criticism of, and comment about the game, is an activity protected by the US First Amendment. Making such comments is very likely to be fair use under US copyright law. In general the author of a work, such as a book or a game, or the maker of a product, has no right to grant or withhold permission to discuss or comment on the work. This is true not only under US law, but also in the law of most countries (perhaps of all countries). The name of the game might well be protected as a trademark. But that does not allow the trademark owner to prevent discussion of the game, clearly identified by the name of of the game. As long as nothing is being sold or rented, or advertised for sale or rental under that name, and there is no attempt to claim that the site is sponsored or approved by the trademark owner, and there is no likelihood of confusion, there is no trademark infringement. This is true under US law, and under the trademark laws of most other countries. A wiki is a specific technology. It can be used for community discussion, or for a company's internal documentation, or for any of many other purposes. Wikipedia has popularized this technology. Not all community discussion sites are wikis, however, nor are all wikis for community discussion. Just as not all novels are books printed on paper, and not all books are novels. In any case, setting up a wiki about a topic such as a game, a movie, or a novel does not require permission from the owner or creator of the game or of any trademarks associated with the game or work. The same would be true for a discussion forum about such a game or work that is not a wiki. If a wiki uses excessive quotes from game dialog, or uses the game's logo without permission, or reproduces other game assets, such as character art, maps, and the like without permission, that might be copyright infringement.
Under Copyright? The first question is: Is this novel still under copyright. This depends on the place and date of publication. In many countries copyright now lasts for 70 years after the death of the author. Some countries use different rules. In the US, a work published before 1978 is in most cases copyrighted for 95 years. Works published after that are protected for 70 years after the death of the author. More complex cases are detailed in this well-known chart. Who holds the Copyright? For most novels, copyright is initially held by the author(s). The author may sell or give away the copyright at any time. If the author does not transfer the copyright during life, it will pass with other property st the author's death. It may pass by will or by default (intestate) inheritance in the absence of a will. The author's surviving spouse children, if any, are often the heirs to any copyrights, but not always. Authors with many works still in print may have s &quot;literary estate&quot; set up to handle their copyrights. Works with multiple co-authors usually have the copyright shared between all authors; in equal shares unless they agree otherwise. Any one copyright holder may license a derivative work such as a translation. A would-be translator of a work still under copyright must find the copyright holder(s) and obtain permission. If the holders cannot be found, no permission can be obtained, and any translation would be an infringement of copyright. The copyright holder could sue for damages after publication. Damages may be quite substantial in some cases. This varies by country and by the facts of the case. In the US The Federal Copyright Office will search its records to try to determine who holds a copyright. They charge a fee for doing so, and success is not guaranteed. Other countries may have similar services. Addition: There is no automatic or guaranteed way to find who now owns a copyright. In some cases the owner does not even know that s/he owns the copyright. If the holder died without heirs the copyright may belong to the government (state government in the US). Research into the author's life may reveal probable heirs. An obituary may list the author's children, if any. Finding them and asking is a reasonable place to start.
Whether published or unpublished, they are still protected by copyright. (They are probably unpublished for copyright purposes, but in the US this makes little difference for any recently created work (that is anything after 2002). For older work see the Cornell chart.) They cannot be copied or distributed without permission, unless an exception to copyright, such as fair use or fair dealing applies. And it is hard to see how either would apply to entire essays simply begin placed in a database. Placing text in a database is probably making a copy, and might be distributing it or publishing it, depending on how access to the DB is granted. Now data from the essays, as opposed to the texts of the essays themselves, are probably facts. Facts are not protected by copyright in any Berne Convention country, including the US, the UK, and the EU.
In general, using content provided by another who incorrectly posted it under a permissive license, such as a CC license, does not grant a valid license from the real copyright holder. That is, if A writes some code (or a song, or creates an image, or whatever else), it is protected by copyright. If B then posts it to the web, with a statement that it is released under a particular license, without having obtained permission from A, then B's &quot;release&quot; is of no value, because B had no rights to grant. If C downloads and uses this content, relying on B's license, then A could take legal action against C. C would probably be considered (in the US) an &quot;innocent infringer&quot; which reduces the minimum statutory damage amount, but does not otherwise change C's legal position. A could, if it chose, bring suit and possibly obtain a judgement including some damages. But to return to the practical case of code posted on one of the SE sites. Given the comparatively short code sections usually posted, and that they do not usually form a complete working program, and given further the stated educational purpose of SE, it is likely that in US law such a posting would constitute fair use, and in the law of other countries fall under one or another exception to copyright. That is a general conclusion, the details would matter. I have not heard of a case similar to that suggested in the question. I find it unlikely that an SE poster would post copyright-protected code without permission, that is valuable enough to be worth an infringement suit, and substantial enough and having enough effect on th market for the original to be outside the protection of fair use. Such a situatiion is, of course, possible, even if unlikely. Note that a cease-and-desist letter is not a court order, and is really only a threat of court action. its only legal effect is to put the recipient on notice, so that continued infringement is not without awareness of the copyright claim. To have legal effect the claimant must actually bring an infringement suit, which is not without cost.
You also retain the right to license the work to others. Therefore you can sell similar rights to MusicBook and anyone else, as long as you do not grant an exclusive license (you have already licensed another party to distribute). They do not gain the right to sub-license your work. If you had executed a copyright transfer, you would have no rights to the work whatsoever (leaving out moral rights for jurisdictions that have them and where they are absolute).
