DIGITAL TRANSFORMATION OF INFORMATION AND ITS

IMPACT ON SOCIETY:

ROLE OF LIBRARIES IN SOCIETY:

Throughout the course of human history, libraries have been the prime platform for seeking knowledge.

SOCIETAL NEED FOR A KNOWLEDGE PLATFORM

LIBRARIES

SPECIAL

LACK OF INFRASTRUCTURE,

FUNDING, FOOTFALLS

However, with India’s burgeoning population, such institutions are facing constant economical, infrastructural and human resource hurdles.

DIGITAL LIBRARIES: BANE OR BOON?

PRO:

• ADDRESSES INFRASTRUCTURAL LIMITATION

• ALLOWS MULTI-

MODAL LEARNING

• MAKES WAY FOR

KNOWLEDGE CREATION FROM THE CURATION

CON:

• FURTHER DECREASES FOOTFALL

• LACKS ‘HUMAN

TOUCH’

WHAT WILL MAKE A 21ST

CENTURIAN VISIT A LIBRARY?

INTERNET ACCESS

SKILL DEVELOPMENT WORKSHOPS

COMPETITIVE EXAM TRAINING

LIKE-MINDED COMMUNITY INTERACTIONS

OPTIMAL MODEL?

Libraries need to undergo a digital transformation whilst still keeping the benefits of having community interactions and intellectual engagement.

Our experience prompts towards a physico-virtual model, which is currently

under implementation as ‘NDLI CLUBS’

MODERN DAY LEARNERS?

GOOGLE VS. NDLI : HOW IS IT DIFFERENT?

This is Shamik.

● Shamik is a 3rd year engineering student. ● Shamik is interested to apply for the PhD position. He

needs references on nanostructured materials to build his paper.

● Shamik has an iPhone7. ● It has Google, YouTube and the NDLI iOS app!

This is Payel.

● Her native language is hindi. Payel is now in class VIII. ● Her final exams are next month. She is particularly scared of Physics. ● Payel has a MOTO-G5 with 4GB RAM. ● It is her pride and joy. ● It has Google, YouTube and the NDLI Android app!

NOW THAT WE HAVE A TECH SETUP, HOW DO WE CONNECT IT TO COMMUNITIES TO INCREASE

FOOTFALL TO PHYSICAL LEARNING ENVIRONMENTS?

● E-learning environment for schools

● Involving all K-12 Stakeholders

● Single point of access for unified academic

resources

● Aimed at building active learners among

users - NDLI club newsletters, quiz,

workshops on themes like STEM, e-

commerce, IoT etc.

NDLI CLUBS: EDUCATION HUBS FOR ALL

LEARNERS, ANYTIME, ANYWHERE

NDLI CLUBS

● Clubs can provide insights on learning outcomes and cognitive abilities to better curriculum

● Will allow development of concept-based questions modelled on learning behaviour

● Student profiles and performance will allow school management to make better decisions

SOME NDLI INITIATIVES TO TRANSCEND THE ROLE OF A

DIGITAL KNOWLEDGE REPOSITORY…

VIRTUAL LIBRARIES ARE MORE THAN A PASSIVE COLLECTION OF BOOKS...

● Like with all other things digital, users expect a lot more customization and interaction from digital libraries - the digital library hence needs to evolve into a bouquet of services instead of just a storage platform

● Apart from collating data and connecting them meaningfully, the end-success of the library will always lie with its users. NDLI clubs encourages the active involvement of users with the content as well as each other to Learn, Share, Grow.

UNDERSTANDING THE MODERN KNOWLEDGE SEEKER:

● Technology and hence technology-enabled access have led to users becoming virtualized

● As a data aggregator, digital libraries can not only facilitate search and browse, but also bring together content libraries and algorithm libraries to compute big-data solutions remotely and real-time!

● So not only can the library store knowledge for its users, it can also evolve to create/compute knowledge by cross-linking programs with data-sets

SURROGATOR

● Makes available pre-print copies of academic

resources that are otherwise unavailable to

learners

● A customizable application that can identify

surrogates for access-restricted publications

in digital libraries

● Surrogator can make a case for the evolution

of specific subject matters through pre-print

indexing and open up a whole new realm of

research

● Application is being tested through NDLI, can

easily be extended to other digital libraries

DATA-DRIVEN CANCER RESEARCH

● India currently does not have the

infrastructure for dedicated bio banks to aid medical research

● This prevents the Indian medical system to learn of and from trends to prepare for subsequent treatment

● NDLI has tied up with TATA MEDICAL CENTRE in Kolkata to develop a prototype for bio-banks that will aid cancer-research

CHAVI COMPREHENSIVE DIGITAL ARCHIVE OF CANCER IMAGING

● Dedicated image banking service

● Will provide annotated images with associated information of cancer patients

● Furthering India’s data banking initiatives

● Library migrating to create a database for bio-banks

PRESERVATION

INTERNATIONAL LEARNINGS ON DIGITAL PRESERVATION:

• National Heritage Digitization Strategy (NHDS):

https://nhds.ca/ Canadian memory institutions are working together to find ways to improve access to digital collections and better preserve cultural heritage

• Tour of Gatineau Preservation Centre

• Co-Lab : A collaboration tool used to transcribe, tag,

translate and describe digitized records from the collection. Also, has a number of open challenges in Transcription, Translation, Tagging and Description

• Library of Congress: International Image Interoperability

Framework (IIIF) is the way to go
