Copyrighting ancient texts I heard that reprints of ancient texts can only be copyrighted for their format, but not their actual text. But if you like the format, how close to the published format can you get before it's copyright infringement? (Also, if my premise is wrong, please correct me) This is an educational question and I am curious if such a case is even possible, and if not, how such a case would go about being decided.
The text of an ancient manuscript would indeed not be covered by copyright. A translation into a modern language normally would be protected by copyright. (Unless it is purely a machine or algorithmic translation.) The formatting of a publication could ber protected by copyright, but only if it includes some significantly original element. (In the US, and in many but not all other countries, only original works or original aspects of works may be protected by copyright. Thus where the copyright is for format the format must include an original element or elements.) If the format was a normal one for the type of publication, ther would be no original content to protect, and so no copyright at all. A work alleged to infringe a copyright on the format would need to be shown to have copied an original element or elements of the prior publication's format.
As for plagiarism, that is not a legal concept, so he can define plagiarism however he wants. It certainly isn't, under any definition I have ever seen on Earth and I have seen many (it has to do with "claiming someone else's work as your own"). As for copyright, a set of questions is (potentially) protected by copyright. If they are copied from somebody else's book of questions, then the book author (or publisher) holds copyright. Let's say that QM invented the questions, such as "What is the Turkish word for Janissary?", "What is the most prominent feature of Jannissary garb?" and so on. Then that set of questions, when put down in fixed form, are protected by copyright, and cannot be copied without permission.
This almost certainly falls under fair use. In fact, there are numerous examples of such books already. You are using a small portion of the work, and it is for a transformative purpose- teaching about it.
I'm going to focus on one part of your question, because I think it is informative to the entire question: "By publishing those data in a copyrighted book are they now in the public domain?" Insofar as copyright is concerned, the "facts" are simply never copyrightable. What is copyrightable is the expression of the fact. So you publish a book and it contains many facts. You retain copyright over how you expressed the facts, meaning the word choice, format of presentation and so on. The discussion of this point always leads people to ask the following two questions: What if the "facts" are closely related to the way they are expressed? For example, a phonebook contains "facts" about phone numbers. The individual numbers are not subject to copyright. But if the way they were organized was clever (i.e. not merely alphabetical) the presentation may be copyrighted. Doesn't that line get blurred? Why doesn't "the presentation order" count as a "fact?" It does get blurred! And courts use nuanced case law and judgment to figure out which side of the line a given thing is. However, one backstop is that if AN EXPRESSION is so closely related to the IDEA BEING EXPRESSED that the IDEA cannot be otherwise expressed, then then the EXPRESSION is not subject to copyright protection. To answer your specific questions: The book is subject to copyright. The facts in the book are not. Someone else could publish a book with the same measurements so long as they are expressing the facts with sufficient difference from the original. I'm not familiar with CUSIP numbers. However, there are two things to say here. (A) it sounds like you are describing a contractual relationship between the people who have the numbers. This is not governed by copyright; it is governed by contract between the parties. If these numbers could be treated as a "trade secret" they might be protected IP in that way. But given that they are likely circulated at least a bit, they don't seem like candidates for "trade secret" protection. To your question, "what is the effect of one person leaking?" If "trade secret" law was doing any "work" here... then yes, the trade secret would be undone once the information was public. But like I said, its likely this is actually all about contracts not intellectual property protection. (B) The "facts" of "which number is associated with which instrument" is likely NOT subject to copyright at any time. The specific numbering code COULD BE copyrighted, but in reality is almost certainly TOO CLOSELY tied to the IDEA being expressed to be copyrighted. Could the number be expressed otherwise? If not, then its likely not protected by copyright. -- Big take away here: You seem to be confused about the concept of "facts" getting into the public domain. That's not exactly what copyright is about. Copyright would protect the expression of facts. An expression can become public domain if it is sufficiently old or if the creator designates it as public domain work. But simply "putting something out there" does nothing to alter the copyright status of the thing.
Physical content The main consideration with physical content is that reading it does not require making a copy, so uncomplicated copyright law is what’s relevant. Copyright law is about making copies (also distributing). Purchase a novel (a physical book which was legally obtained). There is no copying involved (you do not in fact make a copy in your mind, if you're a human). Under the First Sale doctrine, once a copy is sold by the rights-holder (e.g. the publisher, initially to the bookstore or distributor), that owner can do whatever it wants with that specific copy, including reading or re-selling (and anying thereafter can likewise). Books are sold, not licensed. Copyright relates to copying, not reading. It’s true that all (legal) rights are reserved, but the power to prevent resale is not a right. Book (or anything else) on the ground. As above, with the complication that you aren’t at least immediately the rightful owner. But, you don’t have to be the owner of a protected work to read it (otherwise libraries would not exist). The rightful owner might unsuccessfully try to sue you for reading their property, but reading does not cause damage, and your act is innocent (not even negligent), and not wrongful. Eventually (depending on jurisdiction) you may become the owner if the original owner does not reclaim the book. Reading a copy made by someone else. See above about the relationship between reading and copyright. The teacher might maybe be liable for infringement, but you are not culpable (assuming you didn’t encourage the teacher to make an illegal copy). Digital content However, every item of digital content has to be copied many times, in order to actually be read. E.g. a copy is made to video display memory from RAM, which is copied some number of times from RAM to RAM as the program formats and sizes, ultimately reading a copy stored on disk storage (which is installed from.... using N temp files) Typically what happens is that you acquire a copy of a license to use the content. Some number of copies may be statutorily permitted, e.g. the myriad transitory copies created across the internet as you download the work, or on your computer as you install it. The law addresses this matter in part at 17 USC 117, saying that it is not an infringement for the owner of a copy of a computer program to make or authorize the making of another copy or adaptation of that computer program provided: (1) that such a new copy or adaptation is created as an essential step in the utilization of the computer program in conjunction with a machine and that it is used in no other manner, or (2) that such new copy or adaptation is for archival purposes only and that all archival copies are destroyed in the event that continued possession of the computer program should cease to be rightful. Since Congress chose the word “program” rather than “file”, the plain reading of this is that permission is always required to read digital content. One may assume, when you purchase an electronic book at the store (you thus own the recording medium), that the work also comes with specific permission to make those automatic copies required to actually read the book on a computer. In order to read the book you must make some number of copies. Seeing stuff on a web page. Let’s also assume that the material is on the page without permission, but you don’t know that, and it just jumps out at you. This raises an interesting question regarding statutory language and web pages. The statutory language is not at all clear about link-clicking (the statutes don't say anything about "links"), and I don't know of any relevant case law (probably because it would be ludicrous to go after an innocent link-clicker) Infringement is defined in 17 USC 501(a): Anyone who violates any of the exclusive rights of the copyright owner as provided by sections 106 through 122 or of the author as provided in section 106A(a), or who imports copies or phonorecords into the United States in violation of section 602, is an infringer of the copyright and if you infringe, you may be liable. 17 USC 106 spells out those rights: the owner of copyright under this title has the exclusive rights to do and to authorize any of the following: (1) to reproduce the copyrighted work in copies or phonorecords; … (3) to distribute copies or phonorecords of the copyrighted work to the public by sale or other transfer of ownership, or by rental, lease, or lending; … When you go to a web page and click a link, are you reproducing the protected material? Or is the website owner reproducing the material, and pushing it onto you? I don’t know of any decisions that address this kind of technical question. There is no question that the person hosting the infringing material is liable, the question is whether you would be as well? It would be highly unjust to hold the innocent link-clicker responsible. There is a bit of protection for innocent infringement in 17 USC 405(b) Any person who innocently infringes a copyright, in reliance upon an authorized copy or phonorecord from which the copyright notice has been omitted and which was publicly distributed by authority of the copyright owner before the effective date of the Berne Convention Implementation Act of 1988, incurs no liability for actual or statutory damages under section 504 for any infringing acts committed before receiving actual notice that registration for the work has been made under section 408, if such person proves that he or she was misled by the omission of notice. In a suit for infringement in such a case the court may allow or disallow recovery of any of the infringer’s profits attributable to the infringement, and may enjoin the continuation of the infringing undertaking or may require, as a condition for permitting the continuation of the infringing undertaking, that the infringer pay the copyright owner a reasonable license fee in an amount and on terms fixed by the court. (c) Protection under this title is not affected by the removal, destruction, or obliteration of the notice, without the authorization of the copyright owner, from any publicly distributed copies or phonorecords. (You could be prevented from further use of the infringing material, and liable for specific lost profit). Infringement is not defined in terms of what you know or believe about the copyright status of work. Nevertheless, I would expect that in addressing the question of whether a person had in fact made a copy that they would look at the mental state of the individual, looking for mens rea. This could distinguish clicking a link that unexpectedly pushes protected material onto you, versus attempting to obtain protected material by clicking on a link.
The following answer is based on US-law. I am not a lawyer; this is not legal advice. If the book you read is in the public domain* you should be fine. Otherwise what you are doing is copyright infringement and probably not protected by fair use**. One of the rights granted to copyright holders is to control derivative works, and transference to different mediums, which is what your recordings would be. Under US law, whether an instance of copyright infringement is fair use is evaluated on a case-by-case basis, weighing four points: the purpose and character of one's use the nature of the copyrighted work what amount and proportion of the whole work was taken the effect of the use upon the potential market for, or value of the copyrighted work In my non-lawyer evaluation, point 1 depends on what you do in your video (unless you monetize your Youtube video, in which case it is likely to be decided against you), but if you are merely reading the book out aloud, it is unlikely to be in your favor (although it may not be against you as an &quot;educational tool&quot;). Point 2 depends on what is being read, with a informative work (e.g. a textbook) being more likely to be fair use than a creative work (e.g. a novel). Point 3 depends on how much and what proportion of a work you use; since you are presumably reading a whole book, this would most likely be ruled against you. Point 4 would almost certainly be decided against you, as you are essentially creating an unauthorized audiobook. In summary, you can read a book aloud. You can record your reading of it for your personal use. You should NOT upload it to Youtube, or other sharing sites. *Note that different countries have differing rules on when a book enters the public domain, and since the internet crosses borders, multiple rule sets may apply.
I believe the author has published it online. I agree. It is posted at his publisher's website. However, I am unsure if I'm allowed to read it. This answer assumes you are in jurisdiction whose copyright laws is based upon the Berne convention (i.e. the civilized world + USA). Assuming it was the author published it online, it is perfectly legal to read it. Technically, the author is performing his work by putting it online, and by reading it, you are just enjoying his performance. Also, if you are in a jurisdiction with an explicit exception from copyright for personal use, or where fair use allows making copies for personal use, it would also be legal to download it, or to print it on paper (but for personal use only). As for downloading and printing for non-personal use - that is not legal in Berne jurisdictions.
Distribution on YouTube implicates, at least, US copyright law. Shropshire v. Canning 809 F.Supp.2d 1139 (N.D. Cal. 2011), Subafilms v. MGM 24 F.3d 1088 (9th Cir. 1994) Are you infringing? Is the original work eligible for copyright? &quot;It is undisputed that computer programs— defined in the Copyright Act as a set of statements or instructions to be used directly or indirectly in a computer in order to bring about a certain result, can be subject to copyright protection as literary works.&quot; 17 USC 102, Oracle Am., Inc. v. Google, Inc., 750 F.3d 1339 (Fed. Cir. 2014) (internal citations omitted). Are you making a copy or displaying the work publicly? (17 USC 106) You concede that you are doing this in the hypothetical, so we can skip this step. Do you have permission to do this? Some work is licensed to allow your proposed use. If you have permission, then this entire answer is moot. Are you taking what amounts to a substantial taking of the original? Presumably, you will not need to show the entire source file to present the naming conventions and techniques that other developers have used. But, what you do show will be an exact reproduction of the original. In the case of computer programs, all US districts use the abstraction-filtration-comparison test. Computer Associates International, Inc. v. Altai, Inc., 982 F.2d 693 (2d Cir. 1992). The abstraction stage of this test is irrelevant in this hypothetical because the reproduction is exact. Filtration excludes any uncopyrightable elements of the original from consideration (due to scènes à faire, merger, lack of originality). The comparison stage compares what remains after the filtration stage, to determine if the new work takes substantially from the original. Fair use defense If your use is found to be infringing based on the above analysis, the affirmative defense of fair use is available. I can't tell you whether a fair use defense would be applicable or successful in your particular case. However, you can search the US Copyright Office's Fair Use Index for many examples successful fair use defenses when a literary work was reproduced in part or whole for educational purposes. There are also other affirmative defenses available (implied license, for example), or defenses that directly attack the elements of copyright infringement. Some confusion exists regarding &quot;idea/expression merger&quot; as a defense after a prima facie case of copyright infringement has been made. This isn't completely correct. Where idea/expression merger enters the analysis differs from circuit to circuit. In the 6th circuit, merger enters in the copyrightability analysis (paragraph 1. above). But, the 2nd and 9th circuits treat merger as part of the infringement analysis (paragraph 4. above) and in the 9th circuit, merger is an affirmative defense. Ets-Hokin v. Skyy Spirits, Inc., 225 F.3d 1068 (9th Cir. 2000) The idea/expression merger doctrine is not implicated just because &quot;the idea one that is expressing is 'this is the code they used.'&quot; When you need to cite/show the original work for purposes of &quot;criticism, comment, news reporting, teaching&quot;, that is a direct implication of fair use. Using using this justification triggers the full four-factor fair use analysis. (17 USC 107). You don't get to reproduce a work just because you want to say &quot;this is the work they created.&quot;
