In preparation for moving to a new catalog, we have been heavily weeding the j collection.  I have always been afraid that we might have missed something and have erroneous information in the non-fiction section and try to keep to the five year limit.  However, CREW says to ":weed any book that has not circulated in the past two years, when describing the process for weeding picture books.  What is everyone else's rule of thumb for weeding their picture book collections?
