Is it legal to print (non-pirated) textbook pdfs that are made freely available online by the copyright-holder? There are a lot of textbooks (typically out of print, I think) that the publisher/copyright owner has decided to make freely available online as a pdf. (see this, for example of what I mean) Is it legal to print such texts for personal use as long as it is not explicitly stated to be prohibited in the copyright notice on the pdf? It seems to me that this should be fine, since if something is put online not under a pay-wall or on a private database, the copyright holder is presumably fine with people making (digital) copies, then why not physical copies? Of course, I think the answer ultimately is: "Ask the copyright-holder for permission if you want to be absolutely sure", but I wanted to ask the legal community if this sort of thing is legal in general, either because of specific copyright laws, or legal precedent on this sort of thing.
Although the exact answer should depend on the country you are, in general private copies of copyrighted works are allowed. General rules are: You need to have got the work in a legitimate way. That is, that you have purchased a copy of the work with permission from copyright owners or you have got the work from an act of public distribution authorised by copyright owners - if you got it from a website that is not making a copyright infringement itself, you are in the second case. That you don't make a collective or commercial use of the work. (I took these rules from Spanish Intellectual Property law (article 31), but most countries have similar rules, specially in the European Union. Anyway, the exact limits of private copying exception may differ). Since private copying might have an economic effect, some countries collect private copying levies to compensate copyright owners - probably you have already paid for those when purchasing the printer. Therefore, you can print a book downloaded from a website (unless the site is hosting the work without authorization of the copyright owners, as pirate sites do) for your own use. You can't sell the copies or made a collective use of them. Although reach of collective use might be hard to assess, I would suggest that if you want all the people in your class have the book, send them the link so that any one could print their own copy. Update about the USA As the OP has now specified now their country I update the answer with a comment, although an additional answer by anybody more knowledgeable on US law would be great. I'm quite sure that for practical purposes the result is that you can print such a book anywhere in the world. However, I don't know which laws regulates that in the US. Google doesn't return meaningful results for "private copy usa", so I suppose it is know there by another name. Furthermore, statutes in common law countries tend to be less explicit and there might be no case law applicable. For example, I nobody printing a copy of a pdf for himself to read at home has ever been challenged in court in the USA, there might be no explicit rule about the subject.
This may well be infringement, but I agree that you should start by reaching out to the instructor. You don't want to pay a lawyer if the matter can be be adjusted peacefully. In the US there is a special limited exemption to copyright for "use in classroom instruction" which might apply in such a case. I am not sure if there is a similar provision in Canadian copyright law. But the instructor is likely to change his practice if you notify him of your objection, even if he has the technical right to use the photo. At least it is worth finding out. If he won't, then you can always consult a lawyer.
Multipage contracts, like any multipage texts, will likely bear some level of originality and so they will have a copyright owner. Absent a license allowing you to reuse the text, you will not be allowed to do so. The fact that you were a party to a contract represented by the text does not change your position: your contract does not have anything to do with the copyright of its text, therefore you still need to honor the copyright as if you were not a party to the contract. It is not uncommon that the copyright will be owned by the lawyer who drafted the text. Your business partner who supplied it would have employed/contracted one. Or, the lawyer could have provided the text to your business partner together with the copyright (less common). Why wouldn't fair-use be at play here? Don't you already get the permission to copy and modify the contract from the original party when they send it to you? (Is such right only limited to original execution?) The original party, whether it is the copyright owner or just a license holder, can send the text to you for possible copy and modification in the course of executing the contract with that party only. The copy that you receive is provided solely with the express purpose to make you an offer (so that you know the terms of the contract) and give opportunity to suggest modifications i.e. make a counter-offer. To reuse the text with another party you need a permission/license from the copyright owner. Fair-use won't play here because you'd be using the text for the purpose it was created for—executing contracts—as opposed to, say, writing a research paper on language/phrases used in legal documents. Does it at all invalidate the agreement itself if the party that supplied the contract doesn't actually own the copyright to it? After all, if you're not legally allowed to have a copy of the text that specifies the terms of the contract, how would it be possible to adhere to such terms? Most contracts do not even need to be in writing. The text will be just one of the evidences if your contract, not the contract itself. No matter whether you obtained the text legally or not, it still does its job as evidence. Whilst you may well be sued for the copyright infringement, in no way will it affect the validity of your contract, which will still hinge on those well-known 6 elements having nothing to do with the copyright of the text.
All computer programs are not just copyrightable, they are protected by copyright as soon as they are put into fixed form (for example, as soon as I type it on my computer which will save it as a file on a disk). The copyright owner doesn't have to take any actions whatsoever to have a computer program protected by copyright. It’s not just computer programs, even many fonts are copyrighted because they are essentially computer programs. BTW. What I just wrote is also protected by copyright. There are some licenses involved that I agreed to when I submitted it to this website, and which allow the website to publish and you to read this text, but I'm the copyright holder. PS. There is a comment saying “computer programs are not literary works and therefore not copyrightable”. That may have been true or arguable in the 1980’s. It’s not true now. PS. No, stack exchange doesn’t own the copyright to my post, I do. Unless I was an employee of the company and posted on their behalf. Stack exchange needs and has a license to publish this post.
In the US, Copyright does not extend to theories: Section 102 of the Copyright Act (title 17 of the U.S. Code) clearly expresses this principle: “In no case does copyright protection for an original work of authorship extend to any idea, procedure, process, system, method of operation, concept, principle, or discovery, regardless of the form in which it is described, explained, illustrated, or embodied in such work.” Copyright of Ideas, Methods, or Systems - govcirc31.pdf Copyright does protects the expression of a theory. In your case, A computer program is a set of statements or instructions to be used directly or indirectly in a computer to bring about a certain result. Copyright protection for a computer program extends to all of the copyrightable expression embodied in the program. The copyright law does not protect the functional aspects of a computer program, such as the program’s algorithms, formatting, functions, logic, or system design. Copyright Registration of Computer Programs - circ61.pdf So you can develop a commercial computer program that does what the theory postulates, and that program itself will be under your copyright. The idea that you borrow the book from the library isn't relevant; nor would be reading the book in a bookstore.
A book (or any other creative work) published in the 1800s is now in the public domain everywhere in the world (excepting odd cases like Peter Pan where a special rule applies in some jurisdictions.) Anyone may legally quote from such a work at any length with no legal requirement for permission. In fact there is no legal requirement to attribute the quote to the author (although there is an ethical requirement). In fact one may publish a new edition of such a work, unchanged or modified in any way one chooses, with no legal need to obtain permission from anyone or to pay any royalties or fees. If the work were recent enough to still be protected by copyright, a limited quote could be used under fair use, fair dealing or another exception to copyright under the laws of most countries. The exact rules vary by country, and are often highly fact-dependent, so the exact details will matter. If one wanted to quote enough from a recent work that permission is required, the copyright holder, who is often not the publisher, would need to grant permission. That is often the author or the author's heir, but it can be a person or firm to which the author transferred the rights. Sometimes the rights-holder can be hard to identify. Update: it would be possible for a work published in, say, 1890 by an author then young who lived to a fairly old age, dying in, say 1960, to still be protected in some countries, although not in the US. (Anything published before 1925 is now PD in the US.) But Charlotte Bronte died in 1855, and all of her work has long been in the public domain
17 U.S. Code § 107, which governs fair use in the US, says (emphasis mine): Notwithstanding the provisions of sections 106 and 106A, the fair use of a copyrighted work, including such use by reproduction in copies or phonorecords or by any other means specified by that section, for purposes such as criticism, comment, news reporting, teaching (including multiple copies for classroom use), scholarship, or research, is not an infringement of copyright. In determining whether the use made of a work in any particular case is a fair use the factors to be considered shall include— (1) the purpose and character of the use, including whether such use is of a commercial nature or is for nonprofit educational purposes; (2) the nature of the copyrighted work; (3) the amount and substantiality of the portion used in relation to the copyrighted work as a whole; and (4) the effect of the use upon the potential market for or value of the copyrighted work. The fact that a work is unpublished shall not itself bar a finding of fair use if such finding is made upon consideration of all the above factors. Note that commercial/educational use is part of only one factor. Even if that factor is in your favor, it may not be fair use, and even if it isn't in your favor, it might be fair use. Because fair use is determined on a case-by-case basis, we can't really say whether your use is fair use, with or without the donations. That would be the sort of thing you'd ask a lawyer about to get real legal advice on your particular case.
Those posts are talking about making a modified copy of a copyrighted work. The key word is copy. You are not making a copy. Copyright is not about how a physical embodiment of a copyrighted work is treated. You can burn a book and shred a newspaper. Neither of those actions is making a copy. Also, cutting up a newspaper and pasting a picture on your wall has nothing to do with any “derivative works” issue.
