Interested in Language
Writing a title, for example, a book title:
I know that the first letter of each word should be capitalized.
However, prepositions are excluded from this rule.
What else? What other kinds of words that shouldn't be capitalized?
Thanks in advance.
Otherwise, the titles of articles can be formatted in different ways. I suggest that you do a little research online. The Chicago Manual of Style is one excellent source, and there are many others. It's better to get this information from a resource that goes into all the minutiae of formatting. Once you find a guide that you like, you can consult it for all the many style questions that will arise.
I hope this is helpful,
What I mean is concerning writing references.
I am not writing an article or a book; on the contrary, I am quoting.
Then I write the references, that's why I'm asking how to write titles of any written work that I QUOTE from or from which I use the main idea.
Simply copy the style of your textbooks.
Otherwise you can use a style guide: the Harvard style is often used in linguistics. You can get extensive help on how to make references and citations by searching for "harvard style". Yhis is how books are quoted in Harvard style:
The Cambridge Guide to Teaching English to Speakers of Other Languages.
