and a proper class is exceptionally "large." The axiom of class formation ...

More Precisely: The Math You Need to Do Philosophy
We turn to a more general theory of collections. According to class theory, all
collections are classes. Any class is either a set or else a proper class. Every set
is a class, but not all classes are sets. Specifically, the proper classes are not sets
.

Discovering Modern Set Theory: The basics
... at any moment in set- theoretic time, there is some x E X that has not yet been
constructed. Therefore, in particular, if at least one of X, Y is a proper class, then
the pair (X, Y) could not have been formed at any moment in set-theoretic history.

... or the class of all ideas, are members of themselves. Now let R (the Russell
class) be the class of all proper classes. If R is a proper class, then, since R is the
class of all such classes, R is a member of R, and hence R is not a proper class.

Bertrand Russell Memorial Volume
'Class' is the primitive term, and thus every class is either a set or a proper class,
but not both. Since a proper class is not an element, it cannot be operated on in
the same way as with sets. For example, V, the universal class of all sets, is a ...

A Companion to Philosophical Logic
Proper classes are collections 'too big' to be sets; there is, for example, a proper
class of all sets and a proper class of all ordinals. (Proper classes were first
explicitly introduced in von Neumann 1925; for a recent discussion, see Maddy
1983.) ...
