@maxheadroom What's the best practice for adding entries vs. importing on #BookWyrm?

https://mythicisland.com/inverted_frontier_edges.php by @LindaNagata is not on https://books.mxhdr.net/author/7549/s/linda-nagata, but when I search I find many references on other instances that are all for the paperback. Is it "better" to add a new entry for the #eBook or just import one of the paperback editions. Are comments for the different editions correlated, or will my comments and review be isolated because they're for the e-book?
