Writing a book on history of structural analysis and use extensively secondary sources.

To which extent can I copy long paragraphs of the book while clearly indicating one of the following

  • just cite
  • write based on or adapted from

I do not put in quote long passages.

Can I get by placing a grey background from copied passage

Trying to avoid having to paraphrase

    Don’t paraphrase - learn the material and write it in your own words with the book closed. – George White Jan 19 '22 at 23:38
  • @George White that is good for when you want to copy facts without copying expression, but not for when you want to provide supporting source citations.or for when you want to comment on or analyze another work. – David Siegel Jan 20 '22 at 00:42
  • @DavidSiegel I agree. If he is taking words verbatim to comment on past explanations he might want to put it in a box or something. And get copyright permission or an opinion that it was fair use (in US). I took it that he was trying to avoid getting permission. – George White Jan 20 '22 at 01:22
  • @George White when quoting a past work to comment on it, ther is normally no need to seek permission. A copyright holder might be tempted to refuse permission for what might be negative comment,. which is one reason fair use was created. Another is not to burden an author by requiring a request for permission that might invo9lve significant delay in such cases. [...] – David Siegel Jan 20 '22 at 01:30
  • @George [...] In addition when you state a fact or opinion and want to support it by quoting a reliable source, it is normal to directly quote the relevant passage of the source, not paraphrase or just state the facts with a citation. This a reader can see whether the source does really support the statements in the later work. This is what I mean by a "reference quote". – David Siegel Jan 20 '22 at 01:32

    I agree completely. My orientation was formed by the question question saying "use extensively secondary sources". I thought the OP might be planning to make a book that mostly consists of the words of existing book. – George White Jan 20 '22 at 01:55
  • Clarification: I am taking about 2 pages out of a thesis (about 200 pages). inside my book, which will be about 500 pages. – victor Jan 24 '22 at 04:16

When you are citing a source to back up your statements, you may generally quote a reasonable amount. Under US law, this will be a form of fair use Under the laws of other countries, this may be permitted under one or another exception to copyright. The available exceptions and how they work vary from country to country, but reasonable quotes should be allowed in almost every country.

See Is this copyright infringement? Is it fair use? What if I don't make any money off it?

You should:

  • Make it clear what content is quoted, who originally wrote or said it, and when and where it was published;
  • Quote not more than is needed to support your point.
  • Not quote in such a way that your work can be used as a substitute for the source work.

If you are not making a reference quote, but merely reusing an idea from a source, it is usually better to write the idea in your own words, not closely following the structure or wording of your source.

However, if you are criticizing or commenting on what another author has written, you may (and should) quote enough to show what your comments or critique refers to. The same principles apply as with a reference quote: make what is quoted clear; attribute the source; and quote no more than is reasonable needed for your purpose.

Consider whether you really need to quote "long paragraphs" or can just quote key sentences, perhaps along with paraphrases of the rest.

If at all possible, the parts you quote should be only a small proportion of the source work.
