Hello PIGs, A few years ago, I encouraged you to send citations to your published articles or unpublished theses on the topics of pegmatites and their minerals, which I subsequently posted on the PIG page as an annual list of citations, the Hog Holler. As submissions waned, I extracted citations from GeoRef. That was laborious, and I dropped that. So, this is a reminder that you are welcome to offer contributions to the PIG site, and if you have published works you would like to tell the PIGs about, you may send me a citation to those works that I can post or distribute by email. I cannot post or forward any articles unless they are free of copyright restrictions from publishers. GeoRef lists 164 publications in which "pegmatites" is a subject term that have been published since January 2018. Some of them are likely yours. Help other PIGs who do not have access to on-line search and library resources to access them.
