* He published in various forms: Blake didn't just write poems, he also created illuminated books, which are combinations of text and his own artwork. These sometimes include poems, but they're not always poems in the traditional sense.
* Different interpretations of what counts as a poem: Some scholars include shorter pieces, fragments, and even notes in his notebooks as poems. Others focus solely on the longer, more conventionally structured poems.
However, we can provide some general estimations:
* Over 100 poems: A conservative estimate would be over 100 poems, if we focus on the longer, more well-known pieces.
* Many more if you include fragments: If we include everything, including fragments, it could be hundreds, or even thousands of poems.
It's best to think of it as a range, rather than a precise number.
Ultimately, the most important aspect is not counting the poems, but appreciating the beauty and depth of Blake's work.
