Miscellaneous Anchors
Below is a series of links to all the publically available research on a variety of anchors we have found to date (we exclude papers with analyses and other citations because there are so many!). We have made an attempt to find as much as we could, but it is a work in progress. If you know of any additional testing we are missing, please bring it to our attention (contact us)!
