Disadvantages of Electronic Resources
Now, more and more people prefer e-resources to traditional ones, because it can save their time and money. However, with various e-resources flooded in, more and more people are aware of the disadvantages of e-resources.
a) The fact that, e-resources require special devices or personal computers can be looked as a disadvantage. Many e-resources are typically produces to be compatible for certain software which in turn may be not easily available. Since e-resources are dependent on other equipment’s, certain hardware or software failure may affect it. Unless the hardware, Internet connection or battery power that is required by an e-resource reader is readily available, then its electronic document is useless. In addition, e-resources depending on hardware and software and are more easily damaged than a printed book.
b) E-resource reading devices are surely more expensive than printed books. All devices of e-resources require power. There is a growing concern that the e-resources at present may not be accessible or compatible to the futureS e-resources software or devices.

e) E- Resources have unreliable life span. Paper has a much longer life span than most digital forms of storage. Because of the rapid development of new computer systems it is difficult to judge whether the software or hardware will become outdated. As new hardware is developed, structures must be put into place to allow for the migration of existing materials to the new platforms so that they can still be accessed. Methods of preserving the electronic document must also be developed. A high degree of reliability of the equipment must be a part of the electronic devices that handle the replacements for printed books.
f) Many titles that are available in traditional print books are not yet available in an electronic book format.
