Hunting down obscure
ebooks sometimes turns into a proper little adventure, and
your question about 'the assassination of barbara o neill' taps right into that thrill. I dug around in my head for how books like this usually behave on the market: first, check the usual suspects — Kindle Store, Apple Books,
kobo,
google play books, and Barnes & Noble's Nook. If a title is commercially published as an ebook, it almost always shows up on at least one of those platforms. Use the search with and without punctuation (try Barbara O'Neill with an apostrophe, or plain Barbara Oneill), because catalogues can be fussy with special characters.
If you don't find it there, widen the hunt to indie platforms and aggregators like
smashwords, Draft2Digital, or the publisher's own site. Small presses and self-published authors sometimes sell directly as DRM-free
epub or PDF. For academic or niche nonfiction, university presses or specialty publishers might host a shop. I always check
Goodreads and WorldCat too — Goodreads will point to editions and WorldCat will tell you if libraries hold a copy, even if it's print-only.
Finally, consider that some titles are simply not published as ebooks: they might be out of print, unpublished, or only ever released as a zine or pamphlet. In those cases, used-book markets like AbeBooks, eBay, and local thrift/
Bookshop inventories can be gold. I once spent weeks
chasing a tiny print
run and ended up emailing the author for a PDF; sometimes a polite
contact with the publisher or author yields a straightforward answer. Personally, I love
the chase and the little victory when a rare title pops up in my library app — good luck finding it, and may you score a legit copy rather than a dodgy scan.
