Do your libraries not have a system to request books from other libraries? Not trying to be a jerk, I just have looked for some obscure things before and sometimes they had to be requested from other libraries.
https://search.worldcat.org/ is a good inter-library search site. My librarians use it (among other things, I’m sure) to find books/DVDs to acquire for me on ILL, but since the site is public sometimes I just do the search for them and send them a link to what I want when I submit a hold request.
