A new PC is about to enter our saga: a maga obsessed with books and written works. The player was thinking on giving her a relevant Magical Focus, so that her magic would be "book based" too. But "books" felt a bit narrow, and besides, in medieval Europe written material (particularly ancient stuff) can take many forms not quite what modern "books" are, from rolls of papyrus to rune-inscribed monoliths.
So, the alternative "written material" came out. This thread is about trying to reach a consensus about a) reasonable scope and b) "pricing" (Major or Minor - or "too broad for a Major/too narrow for a Minor") for such a Focus.
Admittedly, written material is rather scarce in the middle ages, and writing magically is a very narrow activity. But thinking a little about it, "written material" can be a pretty broad Focus - because all you have to do is to turn something into "written material" and bam, your Focus applies. Of course, this will require extra time (first write, then affect magically). Obviously, you can't do this with Mentem, Ignem, Auram, and most Vim, Aquam, Imaginem. You can do it with much of Herbam and Terram, but it will be conspicuous; and you can do it with most of Corpus and Animal, but it will be conspicuous and rather upsetting for most targets. Also, note that a Focus spread across a broad range of Arts is less useful than one that covers the same "ground" but with only a TeFo combination: because either you'll need to be a generalist, loosing "oomph", or effectively waste part of the scope. Finally, I confess being partial to the aesthetics of the maga inscribing (mundanely or magically) with arcane-looking symbols the surface of stuff she needs to affect.
Putting this all together ... I'd be tempted to say it pushes the envelope of a Major Focus, but it's not quite outside of it. I'd restrict it to affecting targets, or Parts, whose surfaces are mostly (more than 50%) written. Runes and pictograms count, drawings do not (troupe's adjudication for edge cases).
