Print in Libraries--Fast Facts

According to Constance Malpas, the next speaker:

• 1 billion volumes in North American research libraries, 9% of US share in California
  
• 70 million volumes in storage
• 25 million volumes acquired each year
• UC collection growth an average of 1.94% each year
• Print redundancy across collections: Studies show varied results.
  

But:

• average holdings for serial titles in worldcat is 13
• average holidngs for books in worldcat = 9, or a preservation horizon of 50 years at 0.999 .... and up to 40% of book titles have a single insitution holding
• ...so de-duplication opportunities may be less than imagined
