LimitationsDLI portal is browser dependent. Users are not informed about the software/hardware requirement and limitations of DLI
Too many items in the home page to choose. Some information are available more than once
Search/query form is complex
Search results are not ordered
Search results does not match with query parameters
The databases of digital contents are not easy to use independently
All items in a page are not appearing for small monitors
The information appearing on screen are not easy to read
All digital resources are not categorized according to subject and language
Duplicate and wrong data exist
There are items where hyperlinks are expected but not available
There are hyperlinks for items but contents are not accessible
Short notes for digital resources are not available
Representation of all Indian languages and states are missing
To download/print a complete book is difficult
Conclusions
DLI has done a commendable job within a short period of time
User interface should be more user friendly
Data should be more organised
Thorough usability study should be done for effective use of DLI in future
Thank you!
