Reading the Large Library Rules topic, I notice that a few posters find the current Level-Quality system problematic for various reasons. The reasons resonate with me; I find the single book, level and quality approach somewhat unsatisfying myself. The Large Library rules are an effort to address this.
Optionally, it occurs to me that rather than being focused on the Book, you could build a library of books, where you study a subject from the library by reading from as many books as possible. This seems similar to my academic experience of reading this book this week and that book the next, all supplemented by earlier works and often material from outside the official reading list.
To maintain as much of the current structure, keep quality and level, just pour them all into a Library Art or Ability using the existing pyramid point structure, including the experience point build division between Art and Ability. The resulting subject may be high quality or low level, but the trend is toward the mean, I would think, reflecting disagreements among authors. A skilled librarian may be able to cultivate a superior library through inclusion and exclusion.
So, a library would have scores in the Arts, for example, with Q & L. When Master Aquarius studies, for example, Auram, he generates a study total just the same as before, but from several books; the subject is probably checked out during this time, so Mistress Felina will have to wait for the Auram books to be returned. Possibly there could be study with a penalty for multiple readers drawing from the same subject. Medieval libraries seem unlikely to have multiple copies of the same works, but I suppose a covenant might double up the key works. Possibly multiple readers simply divide up the subject points.
Books are written in just the same say as the rules.
It's still desirable to have Great Works - they have high qualities and levels and boost scores, and all the bells and whistles that mage authors are fond of still contribute to the library scores.
This is very much off the top of my head, and forgive me if I have duplicated the approach of others, which seems likely. There are probably problems with this approach. Thoughts?
