If you got to 9.2 then you likely passed through 9 and 9.1.
9.1 tells you about symbol properties, and functions `symbol-name',
`symbol-function', and `symbol-plist'.  It also tells you about the
value cell (but it neglects mentioning function `symbol-value').

9.3 tells you about obarrays and `symbol-value'.  9.4.1 tells you
about getting and setting symbol properties.  And so on.

`i' in Info is your friend.  It has all of these completions for
`symbol' in the Elisp manual:

symbol
symbol components
symbol equality
symbol evaluation 
symbol forms
symbol function indirection
symbol in keymap
symbol name hashing 
symbol property
symbol that evaluates to itself
symbol with constant value 
symbol, where defined
symbol-file
symbol-function
symbol-name 
symbol-plist
symbol-value
symbolic links
symbolic links <1> 
symbolp
symbols-consed

And if you have substring completion there are more than
twice that number of completions of `symbol'.

Another friend: `M-x apropos'.  With input `symbol' it
shows you a ton of relevant user options, other variables,
commands, non-interactive functions, and macros about
symbols.  Enter additional keywords for more focus.
