OK, I'll provide the authors and a little background on each:
Augustus Hippocrates ex Misc.
A strong faerie blooded Ex Misc who was apprenticed in Merinita but lost his Master in Arcadia and was gauntleted by an Ex Misc friendly to the Master. Is obsessed with living forever (and being forever young). In the faerie mirror of Constantinople he was tricked by a trader to pay one year of his apparent age for 10 pawns of Corpus vis. He now looks 22, and after that he wrote:
A beginner's view into the ailments of ageing - Corpus Q6
When his god friend Kiri Silverwing of Bjoernar got pregnant (a well planned stunt involving a templar "good breeding stock", wine and a helping of Augustus' Corpus magic) she didn't like the prospect of painful childbirth. So he cooperated with the Mentem specialist Andrea of Tremere to make pain feel like flying (a positive feeling for Kiri) and eased the physical processes himself. Then the two helpers wrote:
Easing Childbirth, a practical of application of combined Corpus and Mentem magics - Corpus Q6 and Mentem Q9 (bound together)
The Bishop of Ulm (which we discovered after some more research never existed) is a very scholary man. He has a weakness for discussions and delights in visits from the covenant's Jerbiton mage, and even more their (secretly) female scholar. After losing a formal debate and receiving "On the logic of Plato" he donated two of his own books to the covenant and later we also traded a third book:
Church choirs through the eyes of Boetius - Artes Liberales Q11
Art glorifying God - Theology Q11
Advanced arithmetics - Artes Liberales Q11[/list]
Donar ex Misc. was a guest at the covenant. He represents a non-hermetic weather mage tradition and was at the covenant to extract revenge (by humiliation, not by breaking the code) against the resident Flambeau (who had killed off most of his tradition's future by killing young mages and apprentices when they didn't want to join). The book was payment for staying over winter and getting a lab. The revenge was crushing the Flambeau in Certamen and making him smell foul for a moon. The book has an exotic take on how to use weather to harm your enemies:
Storms and Lightning - Auram Q8
NN of Guernicus was the representative of Greater Alps at the Grand Tribunal arguing that our covenant is actually not in Greater Alps, not in Rhine. We don't have a copy of the original argument ("On the superior suitability of Mountains as Borders", Hermes Law, Q10) but after winning at least a delay in the grand tribunal "our" quesitor felt we deserved the counter arguments as payment for his quick rise in status after arguing (and winning) our case:
Why rivers are better borders than mountains - Hermes Law Q13
Magister Ester Nussbaum (don't remember the correct last name, but it shouldn't matter). Of course only known as "Magister Nussbaum" in all correspondence and while travelling is always disguised. She was an apprentice of great potential of one of the founders of the covenant, but had (most) of her gift destroyed in a major lab accident involving much vim and mentem vis. It seems you cannot make a goat into a magical animal with the gift in a lab ritual. Specially not when the goat refuses to stand still and topples most of the lab. After that she was nursed back to (mental) health by the (then) resident Jerbiton. She never recovered fully physically being frail and motion sick. Having a very keen mind still she has developed quite a reputation as a scholar and is an invaluable resource with her very good (theoretic) understanding of magic. Her first two books describe her accident and her (failed) attempts to recover her Gift:
On the burning of the Gift - Magic Theory Q11
Salvaging the magical residue - Magic Theory Q11
After settling in at the covenant as head of teaching and scribes she started reading Artes Liberales and philosophiae. And she started writing letters to learned men all over Europe. She has friends and connections in most universities, but almost none have ever met her. She started out trying to align the theory of Plato with elementalist experiences and started on a long series of books on the philosophical nature of elements:
On the nature of Water - Philosophiae Q11
On the Nature of Fire. - Philosophiae Q11
On the Nature of Air - Philosophiae Q11
On the Nature of Earth - Philosophiae Q11
On the interaction of Fire and Air - Philosophiae Q11
The plan is to have this as a 10-volume set, and then write an over-arching summae on the subject. Paying for a longevity potion by selling seasons as a lab assistant puts this within (theoretical) reach, provided she can keep up book exchange through correspondence.
And then she probably need to get on better terms with Magister Arundo Carriati of Genoa. He seems to (pretends to?) really dislike anything she does, but is a very active correspondent. After a few letters and when tempers started flaring the first time he sent her:
A study of Human Morale - Philosophiae Q7
as a nicely camouflaged insult. And after that they have been (mostly friendly) rivals. Doing formal debates by letter takes time, and they have been at it for many years now. Ester secretly envies Magister Arundo his university position and most of all his large access to students and academic sparring partners. She has collected and refined her arguments with Magister Arundo into her Rhetoric series:
On the Logic of Plato - Artes Liberales Q11
Why you are wrong - Artes Liberales Q11
Why you are still wrong - Artes Liberales Q11
Why you can never be right - Artes Liberales Q11
The underlying faults of your logic - Artes Liberales Q11
In between all the other writing she has been teaching the magi Greek, but during this process she was appalled at the low level of their Latin, so she wrote them a book to improve themselves:
On the Structure of Irregular Verbs - Latin Q11
And finally an old book I found in my archives written by Sigismund von Eiswald ex Jerbiton. He was a gentle gifted magus trying to increase his abilities in Mentem magic by increasing his understanding of the human nature. So to get some insight into the processes and going ons at a University he spent 3 years studying to get a Magister degree. Being a brilliant young man, and with a weakness for the good things in life he spent much of the time in taverns and other buildings of variable reputation. When he was about to return to his covenant he remembered that he had promised to bring some books. His thesis was one, but he could only get one more from the university. So he decided to stay over winter and wrote this one:
101 places to find friends and have fun - Local Lore (Paris) Q10
Hope this was what you were looking for.
