Can Students Cite Folland Real Analysis Pdf In Papers?

Okay, quick and practical take: you can cite Folland in your paper — just cite the proper bibliographic details for 'Real Analysis: Modern Techniques and Their Applications' and the exact edition you used. If the PDF you found is an authorized copy (author/publisher site or institutional repository), include the URL and access date. If the PDF looks like an unofficial scan, avoid linking it and instead cite the published book to keep things clean and legal.

Also remember: textbooks are solid for exposition and widely used facts, but for new results or theorems with historical origin, try to track down and cite the original research paper. If you quote a passage or use a figure from the PDF, double-check copyright/fair-use rules or get permission. When in doubt, your university library or instructor is a great resource.

I get where you're coming from — sometimes the quickest route to a theorem is grabbing a PDF of Folland and skimming straight to the lemma you need. Short version: yes, you can cite 'Real Analysis: Modern Techniques and Their Applications' by G. B. Folland in your paper, but there are a few practical and ethical details to keep in mind.

Practically speaking, cite the published book (author, title, edition, publisher, year) whenever possible. That means using the bibliographic info for 'Real Analysis' and the edition you actually used. If you read a PDF that was legitimately posted by the author or the publisher (for example an official author’s webpage, a university course page, or the publisher’s site), it’s fine to cite that URL in addition to the book citation. If the PDF is a scanned/pirated copy floating on the web, don’t link to that; you should still cite the official book so readers can find the authoritative source and you avoid endorsing pirated material.

From an academic-quality perspective, textbooks are often acceptable citations in homework, class essays, and expository work. For formal research, it’s better to cite primary sources (original papers where a theorem or technique first appeared), but textbooks like 'Real Analysis' are great for background, standard results, and pedagogical exposition. Also, be explicit about the edition and page numbers if you quote or rely on a specific proof. If you directly quote a passage or reproduce a figure, check copyright rules or request permission when necessary — short quotations are often covered by fair use for educational contexts, but that varies.

If you want a concrete citation: Folland, G. B., 'Real Analysis: Modern Techniques and Their Applications', 2nd ed., Wiley, 1999. For BibTeX: @book{folland1999real, title = {Real Analysis: Modern Techniques and Their Applications}, author = {Folland, Gerald B.}, year = {1999}, publisher = {Wiley}, edition = {2nd}}. And if you're unsure, ping your instructor or the library — they usually appreciate careful sourcing and can point out the best primary literature to cite instead of a textbook.
