It has gotten some people asking if the books are all compatible (they are) and what features each book has to make it "Special". I hope this help clears some of that up.
For starters, yes, there is some overlap. The table of experience points and spells per level are all 100% the same. There some spells in common. For example, the 3rd level spell Bestow Curse appears in multiple books since a curse is so central to the archetype of the witch. There is also a lot new material in each one.

The Witch: A sourcebook for Basic Edition fantasy games
This book is designed with the "Basic" rules in mind. So Holmes, Moldvay, or Mentzer or them modern clones like Basic Fantasy or Labyrinth Lord. Largely compatible with my Swords & Wizardry line. In includes:
- The Witch Class
- Six Traditions (Aquarian, Classical, Faerie, Family, Maleficia and Eclectic)
- 381 New Spells
- Monsters
- Magic items
Eldritch Witchery for Spellcraft & Swordplay
Again this book is largely compatible with the S&W line, though in different ways than the Basic Witch is. It includes.
- The Witch and Warlock classes (slightly different than the ones above)
- New Witch traditions, Craft of the Wise, Tradition of the Magna Mater, Demonic, Faerie and Gypsy.
- New Warlock Lodges, The Dark School of the Scholomance, Fraternity of the Bones, Goetic, The Hermetic Lodge and The Secret Masters of the Invisible College.
- New Demons, the Calabim, the Shedim, the Lilim, and the Baalseraph.
- 248 spells
So 17 Witch traditions and 761 total spells!
Currently in the works:
The Winter Witch. the Winter Witch tradition, the Pact of Winter for the Warlock. New monsters and magic items. Lots of new spells. New races
The Black Witch. A B/X dedicated witch, levels 1 to 13. The Black Witch Tradition (no, it's not what you think it is), lots of new spells, new magic items and maybe some monsters. Hags as a playable race.
and finally The Complete Witch a book that combines all these books into one. Maybe...have not decided yet.
