Built-in Functions and Special Forms

[Artist]

Hi,
 I have been using emacs now for over an year.
 and now I like to know how I can do some work with lisp.
 
 How I can find the built-in functions for lisp:

 command-index for emacs or C-h f TAB won't work here cause it will
also give me the function defined in .el or .elc files.

 I am looking more like  more or less like:

(nth N LIST)
(eq OBJ1 OBJ2)
(> NUM1 NUM2)
(% X Y)

Similary for Special Forms:

 I am seeking the list like:

(defun NAME ARGLIST [DOCSTRING] BODY...)
(let VARLIST BODY...)
(if COND THEN ELSE...)
(setq SYM VAL SYM VAL ...)
(while TEST BODY...)
(function ARG)
(quote ARG)
(progn BODY ...)

Thanks for help in advance.

Artist.
