Hello,

Much like Categories are used to organise blog posts, I would ideally like to add a 'Source' field to blog posts that is not the same as WP Users/Authors. 

I would like to 

- add and apply Source as one does with Categories

- allow readers the option of displaying Posts by Source

Can you provide any advice on how best to do this?

Wondering if I'll have to use something that is a partway fit like this:
https://wordpress.org/plugins/change-author/

Thanks for your suggestions,

Bren
