Have there been books that were hard to find but you just had to track them down regardless of the effort it took? It's easy to do in the internet age but I can think of three books I sought out (before the internet).
The Revolt of the Angels by Anatole France. I could not buy it and it was out of print. Not at my local library. I found a copy in a library search on special order.
I did the same with an obscure 1970s book John Collier's Cinema of the Mind, which was an unproduced screenplay version of Paradise Lost.
Also, I Am Legend by Richard Matheson. Surprisingly this was out of print until the mid 90s. I tried ordering it from a book store and they sent me a graphic novel. Ultimately I found a copy in a public library. Then a Tor Books version came out.
