TRADITIONAL LIBRARY DIGITAL LIBRARY
Print collection
Stable with slow evaluation
Individual objects not directly linked
with each other
Flat structure with minimal contextual
meta data

process
Limited access points and centralize
management
The physical and logical organization
correlated
One way interaction
Ex- school and college library
All resources in digital form
Dynamic and ephemeral
Multimedia and fractal objects
Scaffolding of data structures and
richer and contextual meta data
More than scholarly content with
various validation process
Unlimited access point, distributed
collections and access control
The physical and logical
organizations may be virtually
Dynamic real time dialogue
For ex –NDL – National Digital
Library of India

11. CONCLUSION
Digital libraries are not going to replace the physical
existence of document completely but no doubt to
meet the present demand , to satisfy the non local
user digitization must be introduced so that at least
libraries become hybrid nature. The initial cost of
digitization is high but experiment shows that once
digitization is introduced then the cost to manage
this collection will be cheaper than that of any
traditional library.
