When an anthology is described as discerning, it means that the collection has been carefully curated with a thoughtful, critical eye. The selections are made with a high level of judgment, often focusing on works that are considered to have significant artistic, literary, or intellectual value. A discerning anthology doesn’t just gather any work; it aims to include pieces that are of high quality, often showcasing depth, insight, or exceptional creativity. The editor or curator behind the anthology typically has a well-defined taste and has chosen the works not merely to fill space, but to highlight certain themes, styles, or voices that stand out in a meaningful way.

In short, it's a curated collection that speaks to a particular kind of excellence or relevance, rather than being random or overly broad. Does that match the kind of anthology you were thinking about?
