Is it copyright infringement to summarize texts from a powerpoint presentation? I have access to a powerpoint presentation as a student. These slides are part of the course content and every single slide has disclaimer at the bottom that says @McGraw-Hill Education Permission required for reproduction or display I do not aim to copy the material and redistribute it in any way. Instead what I wish to do is learn the material from the slides and then write notes and upload them to a website. But since I learned from the slides, I believe my notes, that will be uploaded/redistributed on another platform to a general audience, will most likely end up looking to a certain extent very much identical to the notes, as if I had copied them directly! Is there any legal issue that should concern me here? Should I move forward with my plan? For your information, the texts in these slides are academic in nature and their content is as summarized as possible. So, on one hand, the texts will be pretty similar regardless the textbook, university, country, since they all talk about the exact same material. And on the other hand, for an introductory course into this scientific field, the texts could not, or should not, be any more summarized nor detailed. Consequently, me too, my notes are not to be any more lengthy, because that would be beyond the scope of the course, and also, not any shorter, because then they will be missing critical details... As a result, I expect my notes to look extremely similar to the &quot;original source&quot;... Is this something to worry me?
Facts are not subject to copyright. Only a specific expression of a fact. When you describe a fact in your own words, then you are the sole copyright owner of that description, no matter who taught you that fact. But keep in mind that in the world of academia it is customary to always state your sources. But that's not a legal requirement. That's a topic for Academia Stack Exchange.
This appears to mean that the author, while retaining copyright, is allowing anyone to make copies without asking permission from the author. This would seem to be similar to a CC-BY license, or perhaps more exactly a CC-BY-ND license, as the author has apparently not granted the right to create modified versions or other derivative works. This does not require one who makes such copies to distribute them free of charge, unless there is another provision not mentioned in the question. Amazon, or anyone else, would be free to sell copies at any price they cared to ask. If the author wanted to limit the sales price, that would take another provision, and might not be enforceable.
In the US, at least, facts - like the speed of light, the name of a dinosaur or the moons of Jupiter - are not copyrightable. But the words or pictures, designs and original work used to express and present those facts in books, websites and other publications by individuals and publishers are copyrightable. (Original work doesn't need to be published to be copyrighted; it is copyrighted at the moment of creation.) See How can &quot;factual&quot; intellectual property be protected? Plagiarism can be copyright infringement; it's copying and presenting work of someone else's as your own. But not all copyright infringement is plagiarism in the sense that someone is claiming others' work as their own: if you're selling a T-shirt with an unlicensed design, you're not really claiming the design is yours; you're just trying to make money. If you use all or part of an image or a quote or a song from a copyrighted source in your own work, you need permission and attribute the source. Or, you have to decide if the amount of the copyrighted material you are using might be Fair Use and you don't need permission. But decisions on what might constitute Fair Use are ultimately decided in court, because that's where can you end up when a person or a publisher sues you for alleged copyright infringement.
You don't say where you are located. Copyright laws are different in different countries, am going to assume US laws. Under US law, a faithful digitization of a book does not get a new copyeight, see Bridgeman Art Library, Ltd. v. Corel Corp., 25 F. Supp. 2d 421 (S.D.N.Y. 1998) and thw Wikipedia article about that case (On the issue of mrequired originality, see also FEIST PUBLICATIONS, INC. v. RURAL TELEPHONE SERVICE COMPANY, INC. (No. 89-1909.) (1991) which dealt with copying a telephone directory.) The court in Bridgeman held that: It is uncontested that Bridgeman's images are substantially exact reproductions of public domain works, albeit in a different medium. The images were copied from the underlying works without any avoidable addition, alteration or transformation. Indeed, Bridgeman strives to reproduce precisely those works of art. ... The mere reproduction of a work of art in a different medium should not constitute the required originality for the reason that no one can claim to have independently evolved any particular medium.'&quot; As discussed above, the law requires &quot;some element of material alteration or embellishment&quot; to the totality of the work. At bottom, the totality of the work is the image itself, and Bridgeman admittedly seeks to duplicate exactly the images of the underlying works. ... [O]ne need not deny the creativity inherent in the art of photography to recognize that a photograph which is no more than a copy of the work of another as exact as science and technology permit lacks originality. That is not to say such a feat is trivial, simply not original. The more persuasive analogy is that of a photocopier. Surely designing the technology to produce exact reproductions of documents required much engineering talent, but that does not make the reproductions copyrightable. The Bridgeman court was actually construing UK law, but the earthlier phase of Bridgeman i and the SCOTUS case of Feist show the same result under UIS law. Note that books and other works published before 1925 are now out of copyright in the US. Copyright can also be lost ion other ways, such as publishing without a copyright notice before the effective date of the 1976 act, and failure to properly renew a work published in the US before 1964. Assuming that the book is not under copyright, neither the library nor anyone else has a US copyright in the PFD. Unless the library imposes some additional restriction by contract, any such PDF may be copied or shared freely. It may even be sold or rented. And the validity of such an additional agreement would be questionable, but since the question does not mention such an agreement, I will not go into that further.
You are framing it wrong. It is not that "they have put a barrier" to public domain information, it is that they have added an additional source of that information. The new source has a barrier, yes, but that does not prevent you from accessing the same information elsewhere. If you own a copy of some public domain data, you are not allowed to prevent other users from accessing other copies (by claiming copyright infringement or the like); you cannot even prevent people from doing copies from the copies you did provide them. But you are not forced to allow other users to access your copy. Consider the logical conclusion if that were the law. The moment that you downloaded some public domain file into your computer, you would be forced to give access to your hard disk from the internet, isn't it? Would you need to leave your home door open if you happened to have a printed copy of the text there? Of course, there is a need to discriminate between "public domain" (without licence) and "not public domain but open licence" (BSD, CC, GPL, etc.). In the later case the licence could be tailored so that the work could appear in archive.org but that it would be illegal to provide it with the business model of Academia.edu1. But that would be possible only for works not in the public domain. 1 To be decided by a judge on the basis of the wording of the licence and jurisdiction.
Section 108(a) is the most useful for an infringer who posts an entire copy of a protected work in public. Subsections(b,c) require that the copy not be made available outside the premises, which precludes internet posting; (d) requires a user request to make a copy; (e) applies only to items that are off the market and transferred to a specific user; (h) allows more copying in the last 20 years of the period when a work is protected (not applicable here). Subsection (a) allows a library or archive to make one copy of a work, as long as there is no commercial advantage to making the copy, the library is relatively public (it might restrict access to bona fide researchers), and a copyright notice is included: this has the fewest restrictions on copying. The internet downloader is not a library or an archive, so the downloader is not granted any permission under 108 to make a copy. Under 108(a) a library can make no more than one copy available, but every uploading or downloading is "making a copy". A library would be contributorily liable for the illegal downloadings of their "customers". It is difficult to know exactly what one can get away with under 17 USC 107 a.k.a. "fair use". I am fairly sure that posting a copy of a contemporary book in the open is not "fair use" even if the intent is to make it possible for dummies to study chemistry: such copying is not at all transformative, totally unlimited, and provides a significant market substitute for the protected work.
The first question is whose law you are concerned with, since in principle you might have violated copyright law in any country, and might be sued under the laws of multiple countries. The US has a concept of "fair use" which is notoriously difficult to apply. When you are sued in the US, you can defend against the allegation by arguing certain things: telegraphically, this includes purpose and character of use, nature of the work, substantiality in relation to the whole, and effect on market. Plus there is a 5th factor to be considered, transformativeness. The court then weighs these factors to decide if the use is "fair". By reading existing case law on the topic (conveniently available from the US Copyright office) you might develop a fact-based opinion of the risk: you would be vastly better off hiring an attorney who specializes in US copyright law to do an analysis for you. Do not hire a programmer to give you legal advice (do not hire an attorney to debug code). You would "fail" on the test of substantiality in that you are copying a highly substantial portion of the original work(s). You would "win" on nature of use (research especially non-profit and commentary are the underlying purposes that drive fair use law). It's not clear how you would fare w.r.t. nature of the work, which is intended to distinguish the extremes "news report" and "literature and artistic work" where copying news is at the fair use end of the spectrum. It is not clear how you would fare on "effect on market", but probably not so badly: are you avoiding some licensing fee? Coupled with the tranformativeness consideration, you are most likely having no effect on the market, since the product that you will distribute is not the original work, but a scientific conclusion about the work. Germany has different laws, and this article would be relevant if you cared about Germany. There was a change in the law that expanded the analog of fair use pertaining to research use. That law allows 15 percent of a work to be reproduced, distributed and made available to the public for the purpose of non-commercial scientific research. That, b.t.w., does not refer to what you are planning to do (unless you also publish quotes); for personal scientific research you may reproduce up to 75 percent. Since this is a new law only a year old, you could become part of the cutting edge in testing the limits of the law. So the standard disclaimer applies: ask your attorney. But note section 60d of the law which legalized data mining, and is squarely on point: (1) In order to enable the automatic analysis of large numbers of works (source material) for scientific research, it shall be permissible to reproduce the source material, including automatically and systematically, in order to create, particularly by means of normalisation, structuring and categorisation, a corpus which can be analysed and to make the corpus available to the public for a specifically limited circle of persons for their joint scientific research, as well as to individual third persons for the purpose of monitoring the quality of scientific research. In such cases, the user may only pursue non-commercial purposes. (2) If database works are used pursuant to subsection (1), this shall constitute customary use in accordance with section 55a, first sentence. If insubstantial parts of databases are used pursuant to subsection (1), this shall be deemed consistent with the normal utilisation of the database and with the legitimate interests of the producer of the database within the meaning of section 87b (1), second sentence, and section 87e. (3) Once the research work has been completed, the corpus and the reproductions of the source material shall be deleted; they may no longer be made available to the public. It shall, however, be permissible to transmit the corpus and the reproductions of the source material to the institutions referred to in sections 60e and 60f for the purpose of long-term storage.
Ultimately whether one work is derivative of another is a question of fact, and there is no absolute rule beyond taking it to a court. Many cases are clear. A Full translation is obviously a derivative work, The definition in 17 USC 101 is: A “derivative work” is a work based upon one or more preexisting works, such as a translation, musical arrangement, dramatization, fictionalization, motion picture version, sound recording, art reproduction, abridgment, condensation, or any other form in which a work may be recast, transformed, or adapted. A work consisting of editorial revisions, annotations, elaborations, or other modifications, which, as a whole, represent an original work of authorship, is a “derivative work”. A mere description of a work, such as a one-paragraph summary, is probably not a derivative work, but as the summary gets longer and fuller, it starts to approach an &quot;abridgment or condensation&quot;. One test is if the summery could reasonably replace the original, at least for some consumers. But there is no clear cut place to draw the line. By the way, If something is a derivative work, it is infringing provided only that the original is in copyright and the creator of the derivative did not have permission from, the copyright holder on the original. Fair use may prevent an adverse judgement, but is still an infringement. As the question referred to fair use, a strictly US legal concept, I am assuming US law here.
