I wish to add a history section to the article on Ethylenediaminetetraacetic acid. I have found a free-access article in the Bulletin of the History of Chemistry (Bull. Hist. Chem.) that contains the information that I want to add. It is also written pretty much as I think it should be for direct use, so there is really not a valid reason to paraphrase the article.

My question is, how can I use it? Is there a limit on the length of block quotes? Might there be an issue with copyright if I use too much of it? I do understand that I would need to reference the publication.

Thanks for your help. Tsember ( talk) 17:06, 13 March 2024 (UTC) reply

Hello, and welcome to Wikipedia. The relevant guideline for quoting non-free source material would be Wikipedia:Non-free content and the relevant policy for doing so would be Wikipedia:Non-free content criteria. Use of non-free content must be limited in order to comply with these two, and you must give a reason as to why you can't paraphrase the article (i.e, create a free alternative).

However, the procedure is completely different if the material is under a free license, such as CC-BY. In that case, you must merely provide attribution. Justarandomamerican ( talk) Have a good day! 17:44, 13 March 2024 (UTC) reply
