This is one area that sometimes dings me on tests. While I can generally
figure out what is meant from context, I only know a handful offhand.

The question here is twofold:

  * Is there a specific name for this category of words?
  * Are there any references that specialize in this vocabulary?

question
words reduplication
Repetitive words (e.g. どんどん, ぺらぺら, いらいら...)
There are actually two types of words here. One is `[擬音語]{ぎ・おん・ご}` which are
onomotopoeia: words representing sounds. Some examples of this are `ワンワン` (dog
barking), `ガリガリ` (scratching, crunching - like ガリガリ君 popsicles), and `ころころ`
(sound of something rolling).

The other type is `[擬態語]{ぎ・たい・ご}` which ["depict non-auditory
senses"](http://en.wikipedia.org/wiki/Japanese_sound_symbolism). Your examples
fall into this category.

Note that both categories contain many other examples that are not repeated,
such as `じっと（見る）` (stare, look intently) or `どしん` (fall and thud).

These onomatopeic words are also described as オノマトペ -- "onomatope," オノマトペア --
"onomatopeia," as well as 擬声語 -- "giseigo."
