While commenting on: this answer I tried to give an exact number of all sorcerer-wizard spells in D&D 3.5.
Trivial searching didn't produce any results.
Therefore, how many spells are there, by level and class?
1017 spells, as of 2005. This significantly does not include spell compendium updates or the latter complete books.
Operating over this list of sor/wis spells, without filtering for sorcerer specific or wizard specific, for all books from 2005 indexed, we get:
This gets us a total cost to learn of (renting access) 50*spell level = 210625 + 4230 pages or 5 blessed books for 12500*5 for 273125 gp, A sizeable chunk of a level 20 wizard's cash and a seriously non-trivial amount versus the 340k gp a level 17 wizard starts with.
From only the core spell lists for Wizards and Sorcerers in the SRD and some tedious counting...
Level 0: 19
While Chet's indexes are clear and useful, they are unfortunately not very complete. Notably, since the spell list's last update was in 2005, it is missing such important works as the Spell Compendium and the latter part of the Complete series (Complete Champion, Complete Mage, Complete Scoundrel).
The most complete database I know of is IMarvinTPA's database. In addition to being searchable, it is available in CSV format.
Naively looking through the CSV sorted by Sor/Wiz levels, I get:
For 1483 spells, covering 6011 pages of a spellbook.
However, the accuracy of this obviously depends on IMarvinTPA's accuracy. While it does grab from a greater number of sources than Chet's index, it
