How to view list of when webpages were last updated through admin interface?


My first post. I am not very technical though was a webkeeper ages ago. The site I work with was created using Drupal.

Can anyone advise me how to view a list of when webpages were last updated through the admin interface?

The site content, (mainly medical text and communication of science), has mushroomed over the last few years and it is difficult to keep track of which pages have been updated with the latest guidelines. Currently I think it relies upon the memory of the webmaster.

Is there a way to keep track of when pages were updated?

I think having a feed direct into the site with updates will not work, as the source, (often research papers and technical guidelines), requires interpretation before appearing on the site I work with.

Any help appreciated!
