I read the title as “VR bookshelf” and imagined someone scanning in an entire book and representing it in the ‘verse in some way. Not to derail from the content here too much, but I think this other idea could actually be pulled off pretty elegantly.
This guy yas some work with books in VR [1] and there is a full library example out there somewhere but I don't have the link handy. Some memory palace solutions make use of bookshelf type interfaces also.
