I'm the librarian for my guild. We have a bookshelf on wheels (an amazing donation by a local cabinetmaker) where the books are stored. They are on the cart in author order; each book spine has a label with the author's name.
I have all the books listed on an Excel spreadsheet so I can sort by author or title. Anyone in my guild is welcome to a copy of the spreadsheet, and new titles/authors are listed in each month's newsletter.
Now the coolest part.
