RPGNow has a big sale going on on various d20 books.
I am not done with the class analysis I wanted to do today so I thought maybe I would highlight some of the books with new classes for your OSR games. Some of these I have reviewed in the past. I am sure there must be others, but these are the ones I am most familiar with. Not all these books are on sale.
A Curious Volume of Forgotten Lore
One of the first, this is the book that launched BRW games and Adventures Dark & Deep. Part of +Joseph Bloch's "What If" experiment of a hypothetical Gary helmed 2nd Edition. I recently went back and reread some of the articles from Gary about the 2nd Ed. game of AD&D that never was. Interestingly he made comments about a 3rd and 4th edition game too! This book covers the Bard, Jester, Mystic, Savant, and Mountebank classes. The mystic was the first class I looked at for the Class Struggles series.
The Complete B/X Adventurer
This is the second book of the B/X Companion series by +Jonathan Becker. Where Adventures Dark & Deep gave us a hypothetical AD&D 2nd Ed, Becker gives us a Companion set that never was. This book gives us some extra rules but the main feature are the classes. The classes are Acrobat, Archer, Barbarian, Bard, Beastmaster, Bounty Hunter, Centaur, Duelist, Gnome, Mountebank, Mystic, Ogre-Kin, Scout, Summoner, Tattoo Mage, Witch, and Witch Hunter. 17 new classes. New classes in B/X and BECMI related games are a bit more varied since races are also classes. But there are a lot of great classes here.
+Tom Doolan published his first work, Basic Arcana all the way back in 2013! This is also a "Basic Era" product. It starts with some "Class Variants"; Dwarf Priest, Dwarf Scout, Elf Sorcerer, and Elf Warrior. For humans we have the Martialist (like a monk) and the Barbarian. All of this and some extra rules on combat and a page of spells.
Magical Theorems & Dark Pacts
A favorite of mine, this book introduces a baker's dozen of new magic using classes and their spells. +Dyson Logos gives us the: Cleric, Wizard, Elven Swordmage, Elven Warder, Enchanter, Fleshcrafter, Healer, Inquisitor, Merchant Prince, Necromancer, Pact-Bound, Theurge, and the Unseen.
ACKS Player's Companion
ACKS is still one of the slickest look games around. +Alexander Macris gives us 19 new character classes, including the Anti-paladin, Barbarian, Dwarven Delver, Dwarven Fury, Dwarven Machinist, Elven Courtier, Elven Enchanter, Elven Ranger, Gnomish Trickster, Mystic, Nobiran Wonderworker, Paladin, Priestess, Shaman, Thrassian Gladiator, Venturer, Warlock, Witch, and Zaharan Ruinguard. So a good collection really. That takes up about 44 pages of the book's 160. New classes have new spells as well. Best of all is a character class creation guide. It look like a similar idea that appeared in Dragon years ago. Basically it reduces any class to a set of points and you point buy a new class just like you would in say GURPS or Unisystem. Maybe one day I'll check out a bunch of classes using this.
Theorems & Thaumaturgy
This is part a class book and of course all the new spells. It's not part of the sale, but +Gavin Norman offers it as Pay What You Want, so make this worth his while. The new Classes are the Elementalist, Necromancer and Vivimancer. The Vivimancer later gets his own book, but these are three very solid class choices.
+James Spahn has been delivering solid classes since the dawn of his Barrel Rider Games. This is a collection, edit of some of his best selling and favorite classes. The first 166 or pages are dedicated to a Basic Era/Labyrinth Lord compatible class. Well this book is huge and we are given 52 classes, divided by category.
Arcane Allies: Alienist, Familiar, Thopian Gnome, Wild Wizard
Doughty Dwarves: Raging Slayer, Rune-Smith, Warchanter
Enchanting Elves: Dark Elf, Greensinger, Half-Elf, Sylvan Elf

New Class Options
One of the most recent one this comes from Genus Loci Games and +Johua De Santo. The classes included here are the: Blood Witch, Chesh, Forrester, Highlander, Mermaid of the In-Land Sea, Mythwood Elf, Pixie, Prodigal, Ruca and the Draken-Knight. I covered the Blood Witch in some detail a while back.
So. Over 120 (give or take) new classes. Not to bad really.
