Advantages of e-resources
  • Accessible – can be accessed from any computer on campus and usually any computer off campus, any time of the day or night, so there is no need to make a trip to the library
  • Easily searchable - each journal can be searched quick and easy often through the complete full text of articles and via online index
  • Speed - Articles/issues  appear online before printed version is available
  • Interactive - Rapid turnaround time means articles can be read, commented by the readers, amended quickly and greater feedback thru the web
  • Links - Hypertext format should be exploited and links to related articles, information on other web sites, stable URLs for individual articles and email alerts when latest issue loaded.    
  • Added Value - Advantages taken  on the web is to add value by using animation, virtual reality and interactive mathematical charts.
  • Inexpensive - savings can be made over printing costs, distribution costs and extra costs by new features.
  • Flexibility - E-journals evolved quickly. They are not tied to a format, printer, and distribution network

Disadvantages of e-resources

  6. One of the problems with internet based resources is uncertainty with regard to continued access . In several countries , Internet has become a political tool in the hands of govts to control civil problems. A recent example is denial of access to internet in Kashmir leading to hugely affecting research and learning. This could be considered as one of the disadvantages of e resources.
