When writing a book title in a handwritten essay, there are different ways to format it. One common way is to underline the title, which is a popular style used in many writing formats. Another way is to italicize the book title, which is a contemporary style used in modern writing. It ultimately depends on the preference of your teacher or professor and the style guidelines you are following.
If you are unsure, the best approach is to check the specific guidelines that have been provided to you. If you are using a specific writing style such as MLA, APA, or Chicago, there are specific formatting rules that you should follow. Be sure to consult the most recent edition of the style guide you are using to ensure you are following the most up-to-date protocols.
If you have more questions about formatting or writing styles, don't hesitate to speak with your teacher or academic advisor. They can provide you with further guidance and resources to ensure that you are writing correctly and adhering to the guidelines of the assignment. Ultimately, it's important to put in the effort to format your writing properly, as it can impact your score and the overall impression of your essay.
