It's hard to compare as the business model has changed, I believe that nowadays it's basically impossible for a library to get an individual subscription to a individual journal: subscriptions are bundled and (online) subscriptions are sold institution wide with contracts running in the millions. That's very different from what Kunth is describing, where individual libraries choosing what subscriptions they need (eg we need the JoA in our (physical) collection so we buy a subscription to that).
