Tagging SDA Books In My Library

Faithlife already tagged the Adventist resources as "Adventist." If you type the term in the Library, you will see them.

Actually, I don't think so. Sometimes publishers have "Adventist" or "Adventists" in their legal name and sometimes it occurs in the subject field (even in a counter-cult book by Hoekema), but those together account for only a third of the books coming up in my library when filtering for that term. What you may see is that a number of fellow users used the mytag-functionality to tag such books as either SDA or Adventist - those would show up when you type the term in the library or - more precisely and more complete - filter for communitytag:(SDA, Adventist) 

I think this will give a more complete tagging than going for individual publishers and authors - possibly giving some false positives. What lacks the communitytag right now (since this functionality is only showing the tag when a large enough number of users have applied it in their mytags) is Lynden's book "Ten minutes in the Word".

One book that you may have missed is The Story of Daniel the Prophet by Stephen Haskell.

I personally don't own that book - and for community tags to work on it, a number of its owners (probably at least 5) need to tag it as sda or Adventist
