" I have also written some poems which have not been collected in a volume. "
- Grazia Deledda

The statement suggests that the speaker has composed poems beyond those included in a published collection. This implies there are additional works by this person that have yet to be officially gathered and released as part of an anthology or book.

On a deeper level, the quote hints at the idea that even accomplished writers continue to produce work throughout their lives, some of which may remain unpublished or uncollected for various reasons. It also reflects on the nature of creativity and the personal journey of an artist, who might have pieces that they feel are not ready for public consumption or simply prefer to keep private. This can be seen as a testament to the ongoing process of artistic creation and self-expression.
