I've come across a few books which I'd like to read, which I'd only be able to access through inter-library loans - but these are purely for personal interest, not actual research.
How much of a "pain" is it for libraries to engage in ILLs? (The use of "may be able to" in the wording makes me think there's some level of negotiation involved?) - should I go for it any time I'm willing to pay the nominal fee, or save it for really special cases?
There's also the option of joining my university's library as alumni, if it's somehow easier for academic libraries.
