Gary Gygax, Dungeons & Dragons (1974), wrote:Sleep: A Sleep spell affects from 2–16 1st-level types (hit dice of up to 1 + 1), from 2–12 2nd-level types (hit dice of up to 2 + 1), from 1–6 3rd-level types, and but 1 4th-level type (up to 4 + 1 hit dice). The spell always affects up to the number of creatures determined by the dice. If more than the number rolled could be affected, determine which “sleep” by random selection. Range: 24”.
It's pretty minimal, but I guess we can work with this: there's still quite some unclarity, like does Sleep affect both friends and foes and if so, how? Or is the spell caster himself affected?
Now, S&W WhiteBox reads as follows:

Spell Level: M1
Range: 240 ft.
Duration: Referee’s discretion
This spell puts enemies into an enchanted slumber (no saving throw is permitted). It can affect a number of creatures based on their hit dice.
Affected by Sleep
- Code: Select all
Victim’s HD Number Affected
Less than 1 to 1+ 2d6+3
1+ to 2 2d6
3+ to 4+1 1d6
In this description, enemies are mentioned rather than creatures. Furthermore, the Sleep spell can, rather than always, affect the number of creatures rolled. So I guess that rules out the chance of affecting friends or yourself, but looking closer at the table it appears that victims of HD 2+ and 3 can't be affected at all and both 2d6+3 and 2d6 of HD 1+ victims are affected. Is there any rhyme or reason to this..? Why was the original description altered in this way?
