Don't throw out funeral books! They are an important record of other family members, friends, associates, and neighbors -- what Elizabeth Shown Mills has called the family's FAN Club.
Studying my neighbors' and godparents' families gave me important clues that allowed me to learn more about where my family had lived before I was born. I didn't realize until then that my parents had known those families in other cities before they moved to the town where I was born.
If you really don't want to keep them, contact your local genealogical society, historical society, and local archives to see if you can find a home for them there. By themselves they may not seem to have much value, but taken as a group, and in combination with other historical records, they could be the key to solving countless problems, simply by being a record of different families still being in contact with each other at a particular point in time. I always try to identify all of the bearers at funerals when I get that information from obituaries and funeral notices in newspaper research -- having the funeral books allows you to widen the net significantly.
In addition to being of value for genealogy, this kind of ephemera is valuable for social history research. Baby books were one of the many sources consulted by Jo Paoletti for her book Pink and Blue: Telling the Boys from the Girls in America.
