If that story back in November about the infested library books grossed you out, I have a solution.
A public library in China has installed a book sterilization machine. It's about the size of a refrigerator, and it uses a UV light to kill germs, bacteria, and viruses. In just 30 seconds, most books with a questionable past can be rendered completely safe for their next reader.
The book pictured at right is probably beyond saving, but most books aren't so obviously damaged. In their case the book sterilizer should be more than enough to kill whatever friendly gifts were left behind by the last user.
In addition to the UV light, this machine also has fan. The fan is used to make sure that the pages are spread wide enough that all are exposed to the light and it also blows a mild perfume onto the books. The change in smell is said to calm readers and reassure them that the book was clean.
The machine was installed in the library some time ago, and while it is accessible to patrons few used it until recently. The library director reports that more patrons are sterilizing the books they check out, especially on the weekend.
