Drupal 7 - Node Limit Publish Module

Parent Feed: 

This module adds a configurable limit to how many nodes of any content type can be published at any one time. This is useful in circumstances such as when a website has created content types of polls or competitions or quizzes but only one of each type can be live and published at any one time. Of course the module allows limits other than 1 in case there is such a circumstance. The default is 0 which means unlimited. A web author may create content and exceed the limits providing the content remains unpublished. This allows for content to be created in advance of publication.

If a web author attempts to publish some content which would exceed the limit, the content is saved as unpublished.

The admin should go to admin/config/content/node_limit_publish to set the limits for each content type known to the system.
