Just find the citation on the web like at Open Library or somewhere, grab it, and add the book as an attachment.

I wouldn't drop it because all the stuff may not be done automatically. If you're going to read the books, you should be spending hours with them. I myself only put them into Zotero when I start reading them. I don't need to crowd it with wishful thinking. It's bloated and gets slower the more entries you add.
