Even though - I guess - you have lovely 'new' copies to borrow (which is always nice) I'm amazed that no one had borrowed them before you! But what's heartening is that it sounds as if your library is still buying in new titles in spite of budget cuts, so that's a good sign the librarians are keen on keeping their graphic novels and manga up-to-date.It seems like supply is actually outstripping demand sometimes, though, as I'm the first person to borrow either. A Silent Voice turns out to have been available for loan since October last year, yet the stamp card was as yet blank before I took it out.
And the titles you've mentioned in the catalogue also seem to show someone behind the scenes is doing some research and buying in a wide range of recommended manga. That's really heartening.
