Complete Arcane has some alternative for magical writings, which might be relevant if you are just looking for your wizard to have his own spellbook and write his own scrolls (as opposed to being able to read something someone else has written). I only have a physical copy, but I'll summarize some of it below - if you have access to that book, relevant pages are 138-139.
Essential characteristics of scrolls:
- Single use only (once it is "read" the writings are gone)
- Spell completion device (only accessible to spellcasters, requires deciphering, may require level checks when spell level exceeds the
- Usable by means of Use Magic Device
- Must be physically manipulated in a complex way
- Must be in user's hand to be used
- Use provokes attacks of opportunity.
Gemstones (held and waved during castings, casting "depletes" them)
Incendiary (specially treated paper which burns during the casting)
Macrame (complex weave of precisely tied knots, casting includes pulling specific strings to unravel the pattern)
You get the idea - essentially, as long as the mechanics of usage are fairly similar, anything goes (with GM's approval, of course). In the same manner, your blindsighted wizard doesn't need a spellbook of paper and ink - he can use "pages" of wood, sheet metal or stone and carve his writings into them. Or he can have a series of coded notches and holes on a weapon or staff - or even pieces of string or rope with special sequences of beads and knots.
If he needs to read the writing of others, your wizard can have someone else read it to him, use spells (scrying, Scholar's Touch, Polymorph into a sighted form or even use Magic Jar to posses someone else's body etc. etc.), or simply have a "seeing eye" familiar to scry through.
A final point - if you really are interested in playing a blind character, don't try to circumvent this limitation with X-ray rings etc. This is a curve-ball, but you'll miss all the fun if you manage to have an effectively sighted "blind character".
Also, you may wish to consider other arcane/divine casters, for which blindness doesn't undermine their fundamental class feature. Some options include Sorcerers, Warlocks (from Complete Arcane, and imho more suited for a dark "Illidan" theme) and, you can have a look at Pathfinder's Oracle with a Clouded Vision curse and Witch (which have a familiar to teach him spells instead of a spellbook)
