Keep it simple. Start with the most recent and work backwards. The ones you’ll read first are the ones you can find first.

I was lucky - I have membership in two neighbouring cities’ library networks, both with no fee inter-library transfers. And one of them allows members to make up to three purchase requests per month. I was never knocked back unless it was impossible to buy it as it was no longer in print.

Then came the online used book hunting (eBay, ABE and Fishpond) and every used book store I could find.

And of course, the commitment to extended reading daily. I’ve been at it for a couple of years.
