How we cite

This is the current list of all citations used on SixLinks, both currently and in the past. We make every effort to keep these links up to date, and their last update date is listed on the citation page. The citation numbers are permanent, and may list citations no longer used on the site. Newer citations get new numbers.

Why we cite

It's important to know where information comes from, and to not simply take our word for it. The citations, in pages, and in this list allow you to check up on our research, and make it better. We welcome all comments!
