What term describes a collection of various writings, such as songs, stories, or poems?

The term that describes a collection of various writings, such as songs, stories, or poems, is "anthology." An anthology serves as a curated compilation that can spotlight a particular theme, genre, or collection of works by diverse authors. This makes it a valuable resource for readers looking to explore different styles, voices, and perspectives within a single volume.

In contrast, other terms do not fit this definition. An anecdote refers to a brief, often amusing or interesting story about a real incident or person, rather than a collection. Alterity relates to the concept of 'otherness' and is used primarily in philosophical discussions regarding identity and difference, while aphorism refers to a concise, memorable expression of a general truth or principle. None of these terms encapsulate the idea of a compilation of various literary forms like an anthology does.
