There are many sources of danger to the new technologies. As librarians you already worry about sunlight, humidity, information obsolescence, misplacement, patron damage, and perhaps theft. You now have these problems and more. The patrons can easily do more damage now than ever before. Files, computer software, and even the hardware are not particularly durable.
Files are susceptible to damage from a variety of unconventional sources.
Never before have you had books in your library that can be lost or damaged if the electrical power suddenly spiked or went out. Of course, there are no guarantees against fire, floods, earthquakes, and riots. New skills will be needed for recovering lost or weird data. Patrons will tax your creativity to the limit with requests for new and ever changing digital solutions. Another problem area is related to the perception that electronic files often do not look inherently valuable.
