Why does the following sentence contain など?


If you have read Japanese Wikipedia articles such as [this
one](https://ja.m.wikipedia.org/wiki/%E3%81%8F%E3%83%8E%E4%B8%80), you will
have come across sentences like the following.

> この項目を加筆・訂正 **など** してくださる協力者を求めています

My translation of the sentence goes like this:

> We are looking for collaborators who would be so kind as to improve and
> correct this item.

What stumps me about the sentence is that it contains など. My research
indicates that など is attached to nouns. If I try to make a literal
translation, I will get something like this.

> We are looking for collaborators who would be so kind as to make
> improvements, corrections and so on for this item.

If I didn't add “for”, the sentence would be grammatically incorrect in
English. Maybe I'm overthinking this, but does the sentence really need など in
it?




など can attach to all of the following:

  * A noun 

> 本などを読む

  * Dictionary form of a (non-suru) verb

> 本を読むなどする

(This is slightly stilted; とか and たり/だり are more common in informal settings)

  * A suru-verb

> 読書など(を)する

(を is optional even in formal sentences)

All suru-verbs are basically also nouns, and など can even attach to ordinary
verbs, so I think the last item is not surprising.

By the way, the sentence can be rephrased to この項目 **の** 加筆・訂正など **を**
してくださる協力者を求めています, which is a bit closer to your "literal" English translation
([this question](https://japanese.stackexchange.com/q/4006/5010) is related).
