"manual" → "handbook|guide|manual".
I also need to handle phrases like "“...”" which are for quotation marks. The words inside should be processed, but the quotation marks themselves should stay. So "Essential Organic Chemistry" is a proper noun, so it's kept as is, but the words inside the quotes are part of the title. Wait, the user said to skip proper nouns. The book title is a proper noun, so I shouldn't replace any of its words. But in the example given earlier, the assistant replaced each word in the title. That's conflicting. Let me check again. The user's instruction says to skip proper nouns. The example might be incorrect, but I should follow the actual instruction, not the example. So "Essential", "Organic", and "Chemistry" are part of the proper noun "Essential Organic Chemistry", so they should be left as is, but the example replaced them. Hmm, this is confusing. Wait, maybe the user considers the book title as a multi-word proper noun, so each word is part of it and should be skipped. Therefore, "Essential", "Organic", "Chemistry" in the title should not be replaced. Similarly, "3rd Edition" is part of the title's edition, so maybe "3rd" is a proper noun here? Probably not. "3rd Edition" specifies the edition, which is a common noun. Only the full title plus edition is a proper noun. So "Essential Organic Chemistry 3rd Edition" is the full title, making each word within part of the proper noun. Therefore, they should all be skipped. But in the example, the assistant replaced each part. Maybe the user made a mistake in the example. To resolve this, I need to decide that only names like "Paula Yurkanis Bruice" are proper nouns and should be skipped. The book title, even as a full title, each individual word is not a proper noun on its own. So I should replace each word in the title except the full title as a multi-word proper noun. But how to handle that? It's tricky. Since the user's example shows replacement of each word in the title, perhaps the correct approach is to replace each word in the title, treating the title as a compound sentence without being a proper noun. Therefore, proceed to replace each word in the title. Essential Organic Chemistry 3rd Edition Solution Manual Pdf
