The latest edition of the spreadsheet is: 5466.Denominations and Theology - 28 January 2017.zip
The reference guide is: 0763.Theology and Denomination Tag Reference - 5 April 2016.doc
Rather than add hundreds of new authors this time, I have mainly been checking the nearly 7000 authors already present against Bibliographical Dictionaries and Encyclopedia entries in Logos resources. The spreadsheet now records whether the authors are mentioned in works such as the Baptist Encyclopedia, Book of Saints, Jewish Encyclopedia, Lutheran Cyclopedia, SDA Encyclopedia and the massive Cyclopædia of Biblical, Theological, and Ecclesiastical Literature, along with its supplement and addenda (see the spreadsheet notes page for the complete list so far). This has allowed extra data to be added for existing authors, though it is clear that there is a minor discrepancy in the dates of birth and death for many authors. I've tended to favour the most recent publication.
I've also added theology categories for amillennialist, premillennialist, postmillennialist, annihilationist, theistic evolutionist and creationist. The spreadsheet differentiates some young earth and old earth proponents as well. I'm open to other suggestions, particularly if they are backed up by reliable starter lists of candidates.
As always, feel free to make suggestions, corrections, etc. and I'll try to add them as soon as I can. I've updated all the collections available through the Faithlife Group as well (https://faithlife.com/logos-library-theology-denomination-tags/about).
Note that the spreadsheet contains far more information than the collections in the Faithlife Group, but it is too unwieldy to create all the collections that could be created from the data in the spreadsheet, such as denominations with fewer authors and bespoke groups such as Female Lutherans, nineteenth-century Anglicans and 'either sixteenth-century or Catholic'.
I would love it if the data here was available directly in Logos, as suggested here (https://logos.uservoice.com/forums/42823-logos-bible-software-7/suggestions/9285627-library-hierarchy-and-filtering), and part of a larger database of biblical issues and stances, as suggested here (https://logos.uservoice.com/forums/42823-logos-bible-software-7/suggestions/17871697-create-a-database-of-biblical-issues-and-stances-w).
