Effect of Producing a Second Edition of a Book on Book Reviews

I am considering revising/extending my “Selected Poems”, as there is new material which I would like to include. Consequently I am thinking of producing a second edition.

I would be grateful for the advice of my readers regarding whether a second edition would mean that the reviews in respect of the current (and only edition) would be lost? Or is it possible to publish a second edition whilst keeping the reviews for the first one?

You can find my “Selected Poems” here, https://www.amazon.co.uk/...
