Additional analysis of the multi-institution study data, including citation analysis as well as application of The WHY Method, appeared in Volume 16, Issue 4 of Evidence Based Library and Information Practice in December of 2021.
Our first publication of data from the multi-institution study applying the revised form of the WHY Method taxonomy, appeared in Volume 82, Number 5 of College & Research Libraries in July of 2021.
Our initial pilot study, which employed our expanded/modified version of Leeder, Markey & Yakel's taxonomy, appeared in Volume 80, Number 3 of College & Research Libraries in April 2019.
This is a publication from the Proceedings of the Association for Information Science and Technology (February, 2019), sharing data and analysis from our pilot study originally presented at a session at the annual meeting of that association in October, 2018.
The taxonomy we use was published in its original form by Chris Leeder, Karen Markey, and Elizabeth Yakel in this article, which appeared in Volume 73, Number 2 of College & Research Libraries in 2012.
This is a copy of our slides presented at ALA Annual 2019 - the data and analysis presented are built on our taxonomy, although the name "The WHY Method" had not yet been established, and so isn't present on these slides.
