I took the liberty of copying in the equivalent data elements from Sierra and from LBS. The OLE spreadsheet was sufficiently complex that I didn't want to tackle it.

For the purposes of discussing missing patron record elements, the most important rows in this composite spreadsheet are 35 through 106. These contain the elements from each of the 3 systems that I did include that do not appear to have equivalent elements in FOLIO yet. I also tried to equate certain elements from those sources that are missing with missing elements from the Voyager records that I am familiar with, e.g Voyager patron.title with LBS borrower.person_titles. So Theodor and Uschi, please check those carefully. (It appears that in Google sheets you do view/freeze/ so that you keep the top row in view while looking at lower rows. I didn't know this, so I thought I'd pointed out in case it was useful to others.)
