resource will create a singluar resource i.e. all the routes of resources but without index.

It's useful for things like "account".

Here's an explanation from the official Ruby on Rails guides:

• Resource Routing: the Rails Default
• Singular Resources

One is plural, one is singular. Good example on http://guides.rubyonrails.org/routing.html#singular-resources

Basically if your representing something which has more than one possible URL - i.e. you can look up multiple different books or authors, use map.resources. If you want to just look up a singular resource. For example the current user or the one and only Admin page, use map.resource
