I am trying to clean-up my mother's Calibre - she requested that I go through and check that all the series titles are correct, that she has all the titles from that author and that I remove any author that hasn't written a book in the past 5 years.

It is quite the job, but I am doing this as a birthday present for her (at her request). But in doing this I am finding some of the authors are listed both ways - First Name Last Name as well as Last Name, First Name.

I have calibre sorting author names by first name, last name. but, for some reason, some of the author names are Last Name, First Name

I want to do a search to find the books that have the author listed as Last Name, First Name, then I can run the "Quality Check" plug in to fix those.

Tried search for , (comma space) in the Author name field - it gives me all the authors

Tried search for , (comma space) in the Author_Sort field - I get all the authors

Tried search for , (comma space) in Advanced_Search - again all the authors

Anyone have any suggestions? My mom is picky, and wants everything "correct" so she can easily move all the books from an author to her iPad. Since she has so many books in Calibre, she just moves books from one author or one series over at a time (it is easier for her this way).

Any help will be greatly appreciated.
