Plus having a library card often gets you access (even remote access!) to lots of expensive services - I use the OED, J-stor, etc. from home with gusto. I will say there's a small dark side to having gone digital, many libraries have culled a lot of their holdings, and/or can't afford to buy as many books as they once did (have to pay for those licenses somehow...). It's likely that there's less demand, but it still makes me a little sad.
I haven't noticed any reduction in catalog size or variety over the years (US), maybe I've lived around well-funded systems? If anything it's become more varied with time. The only annoying thing is having to filter out eBooks every time searching the catalog.
RE: culling, Yeah, there is stuff (I notice manga not reprinted since the 90s, they didn't hold up physically that well and they loaned mainly to teens) that I remember being common that has been culled.
e.g. My library system doesn't have a copy of any of the volumes of "Please Save My Earth," and that was a title that many libraries had if they had any manga at all, in my experience.
