This is a part of a series of House rules I use, that I'd like to call "Reversed detailing". Here is a link to part I: Laboartories.

As an academic myself, I have had somewhat difficult to cope with the rules for books. For me there is four flaws in the (in other ways good) rules.

- There are two seperate rules for text: Summa and tractatus (i.e the rules are not streamlined).
- You can't read the same tractatus twice (because of munchkin reasons I presume) which is a somewhat strange way of looking at written knowledge. You also have to keep track of which tractatus for which spell you have read.
- In real academic texts, nobody seldom writes a beginners book (score 1-5), and an intermediate (6 to 10) to be able to write the advanced book (of 11 and up). They simply start at advanced from the beginning. Why would't they?
- With summas: It's increasingly difficult to learn from books, but not increasingly difficult to write them. In truth, it's almost always the other way around. It takes months for an accomplished academic researcher/writer to make one article that other academics read for ten minutes and then say: "meh, I knew all but the new results from table x." And that is with modern technology.

Now, my house rules are somewhat more difficult to calculate, however one big benefit is that you only need one formula. You are also not keeping track of ink, color, vellum, binding and such. It is all (sort of) calulated into the formula.

Here we go:

- All books have a Range: between level x and y, where x is the art score you must have to be able to start reading it, and y is the maximum score you can have from it. Examples of levels may be 0-5, 5-10 and 18-19.
- The complexity (time) to write the book is as much as the number of EXP, the book contains. A book between 0-5 contains 15 exp. a book of 19-20 contains 20 exp.
- The number of exp a character is able to write (speed) in a season is determined by the skills (Artes Liberales + Profession: Scribe) x2 + possible virtue/flaw bonuses. A skilled academic writes more quickly because Artes Liberales lets him/her find and reuse more good and exact phrases and passages.
- One can write a maximum of as high a magnitude equal skill level in Artes liberales. A writer needs Artes liberales 4 to write about level 20-24 and so forth. (This also makes Artes Liberales a more useful and relevant skill, which it in my opinion should be).
- The book's quality is: Artes liberales + Author's Magnitude of current art (alternatively the author's score in the corresponding mundane skill) + Communication + Any other bonuses.

Example: A winter magician with Ignem 35 is about to write an book of Ignem for level 30-35. In order to even bring that teaching to formulate the complex instructions required, he must first have 7 of Artes liberales. When he writes he has Artes liberales 7 and Profession Scribe 4. He writes (7+4) x2= 22 points per season. Writing 30-35 thus requires (31 + 32 + 33 + 34 +35) / 22 = 7,5 ≈ 8 seasons.

''Quality: Artes liberales 7, Ignem 35 (Magnitude 7) Communication + 0 = 14.

Thus: Books of high magnitude is therefore extremely rare, always written by winter magicians and therefore extremely extremely extremely valuable. Maybe even worth starting wars for?

Also

One can not interpret what level an unknown hermetic book is, if the magnitude of the art described in the book is greater than the skill of Magic theory. Which makes a librarian with high MT score most valuable and necessary.
