Everything I needed

Not only does this plugin show you your broken links, it allows you to see the pages they are on, easily identify them, and fix them with minimal effort. When the broken link is on another site where a page was formally hosted, this plugin directed me to an archive site where I could get the information I needed to create a proper fix for the link. Plus, if you just want to clean up all the links on your site (with multiple contributors we had multiple copies of images and pdf files for download), you can see a list of all the links on your site so you can clean up duplicates. Great plugin!
