Are we witnessing the end of static published guidebooks?<p>Why spend $25 on a book that is outdated by the time it hits store shelves?<p>I’m dubious about the idea of this sort of format replacing books that don’t benefit from continual updates. I’m also curious if the one-off payment is what is best-aligned with what the market wants. Not a direct analog but Masterclass switched from one-off purchases to subscriptions. No inside knowledge to know what prompted it but I’m curious how that has changed their business.
