@davidfor-
Thank you for your time offering options and their explanations. I had no idea there were so many possibilities for a simple task!
My objective is to display a running total (total number of books read) in the tag browser that exist in my custom "read" column. Of course, I can search, sort, or create a virtual library (with thanks to BetterRed) but I simply want to add an entry similar to what exists now displaying totals to the right similar to "authors," "formats," "publishers," etc. The current "read" column is not a composite column. (I only learned what that was during this thread)
If I create a new composite column, type: "Column built from other columns," how do I point it to the existing "read" (type: date) column? What is needed in the template to simply acquire the total of the "read" column? I do not need any other information, just a total.
Many thanks,
Patricia
