I recently needed to add multiple posts to a new category I had created on one of my WordPress blogs. I really didn’t want to have to have to go through each post individually, manually adding the new category to each one. I therefore searched around and found this great plugin.
The “Batch Categories” plugin allows you to filter through your existing posts (you can apply multiple levels of filtering) by Date, Author, Status, Title, Existing Categories or by using keywords (even allowing wildcards). Once you have done this, you can select the posts you desire from the shortlisted selection and either add or remove them from a category all at once. This is exactly what I was looking for! Here are some screenshots of the plugin in action.
