Stop it right now!
As Mary Kelly said on her Awful Library Books blog:
I urge you to saddle up your dinosaur and get out of the way...I am pointing the finger at librarians who refuse to get rid of [outdated] stuff for the utterly stupid reason of “but we won’t have anything.” Guess what? You don’t.It does take time and energy to weed your collection but it also takes time and energy for your library users to browse your church library shelves. Your library is there for them.
To quote another old song: " accentuate the positive, eliminate the negative."
