Institutional Repository@BRACU library
Institutional Repository using Open Source Software Dspace funded by INASP, UK
- collect and preserve various teaching and learning materials and research outputs generated by BRACU academics, researchers and students and ensure access to these resources to the users.
April 2007- April 2008
(2007-2015)

Integrated Library System@BRACU
A complete Integrated Library System (ILS) using Open Source Software Koha funded by ELSEVIER Foundation, UK
- implement a complete library automation system using open source software Koha and develop ourselves as local resource, and in turn help to build capacity in other libraries who may want to move to automation using Koha.
- Convert data from the existing library systems into International Standard format (MARC 21)
March 2009 – February 2010
(2007-2015)

Discovery Tool@BRACU
Next Generation Open Source Discovery Tool VuFind funded by INASP, UK
- to offer access and discover all of BRACU Resources (catalogue records, digital library items, institutional repository, databases, and e-journals) in one single search-and-browse system in a robust, and distributed digital environment.

COOPERATION, COLLABORATION AND INNOVATION
Building next generation Digital Libraries
16Ayesha Abed Library
Network of IRs
• Establish a Network of Institutional Repositories in Bangladesh Academic Institutions to aggregate the digital research output (theses, dissertation etc ) of the member institutions into a single access point for end users.
17Ayesha Abed Library
Network of IRs
BenefitExpand access to research and impact of
research both in Bangladesh and internationally.
Increase the amount and diversity of scholarly output
Preserve and maintain the research output of academic institutions in the long-term.
18Ayesha Abed Library
Network of IRs
Benefit
Facilitate more timely access to research and scholarship Promote the use of standards and best practices, guaranteeing the international interoperability of their content through OAI-compliance and metadata standards
19Ayesha Abed Library
Network of IRsModel
Centralized ModelDistributed ModelHarvesting Model
20Ayesha Abed Library
Centralized Model (IRs)
Central IR
Institution 1
Institution 2
Institution 3
Institution 4
.
.
.
User sends out a search query
Central repository returns aggregated
result
Each InstitutionInputs their data into the central
repository
21Ayesha Abed Library
Centralized Model (IRs)
Advantages Has complete control of the whole process from
article deposition through to the user interface Software selection Able to manage preservation issueDisadvantages It is an expensive option It may surpass the existing institutional repositories
22Ayesha Abed Library
Distributed Model (IRs)
Virtual Interface
Institution 1
Institution 2
Institution 3
Institution 4
.
.
.
User sends out a search query
The intermediary virtual interface sends out the
search request to individual IR using protocols such as
Z39.50, SRU/W
Individual Institutional Repository
responds with the search results
User gets an aggregated result view through the virtual interface
23Ayesha Abed Library
Distributed Model (IR)Advantages Providing up-to-date metadata as it provides instant
access to source locations of metadata Relatively very less expensive as compared to
centralized model
Disadvantages No enhancement of metadata Network dependent Not many IRs support Z39.50 or SRU/W
24Ayesha Abed Library
Harvested Model
Virtual Interface
IR 1
IR 2
IR n -1
IR n
.
.
.
Harvests metadata from individual
repositoryProtocol: (OAI-PMH)
User sends in the search
query
Virtual Interface returns the
relevant search results
25Ayesha Abed Library
Harvesting Model(IR)
Advantages• Unqualified Dublin Core is mandated to be
OAI-compliant, however, more complex metadata schemas can be employed.
• The institutional archives employ software which supports OAI-PMH
• Harvesting can be carried out by automatic scheduled tasks
26Ayesha Abed Library
Harvesting Model(IR)
Ayesha Abed Library 27
DisadvantagesExposed metadata served by the services may
not always be updatedNeeds to support protocols like OAI-PMHEvery member Institution will need to follow a
fixed set of rules when entering metadata in their respective repositories for ensuring consistency.
Which Model to Select?
Harvesting Model• Harvesting model has many advantages as
compared to other models• It has gained worldwide acceptance• It makes easy to share information about
scholarly resources and to offer enhanced resource discovery tools.
• It has been adopted by thousands of institutions around the world.
28Ayesha Abed Library
Establish a Union Catalogue
• Needs for Union Catalogue Discovery Resource Sharing Copy Cataloguing Cooperative Collection management
29Ayesha Abed Library
Union Catalogue Models
• Distributed Virtual Union Catalog• Centralized Union Catalog
30Ayesha Abed Library
Distributed Virtual Union Catalog Model
Virtual Catalog
Institution 1
Institution 2
Institution 3
Institution 4
.
.
.
User sends out a search query
The intermediary Virtual Catalog sends out the
search request to individual
institutional DB using protocols such as Z39.50
Individual Institutional DB
responds with the search results
User gets an aggregated result view through the Virtual Catalog
Local OPACs
31Ayesha Abed Library
Distributed Virtual Union Catalog Model
• Advantages:Relatively easy to implementLess time and efforts requiredEasy to extend and Easy to disconnectReal time searching and retrieval in all
catalogs
32Ayesha Abed Library
Distributed Virtual Union Catalog Model
• Disadvantages: Slower in retrieving results Limited sorting/relevance Duplicate Searching inefficiencies Varying quality Depends on availability of local OPACs
33Ayesha Abed Library
Centralized Union Catalog Model
Central Catalog
Institution 1
Institution 2
Institution n -1
Institution n
.
.
.
User sends out a search query
Central Catalog returns aggregated
result
Each InstitutionInputs their library
catalog data into the Central Catalog
Local OPACs
34Ayesha Abed Library
Centralized Union Catalog Model
Advantages:More accurate search resultsSuch results returned quickly for large groupsBuilt it once, less individual configuration
necessaryCentralizes the cost of technical supportMinimize Cataloging cost sharing bibliographic
recordsConsistent indexing and Searching policy 35Ayesha Abed Library
Centralized Union Catalog
Real-time informationDisadvantages:Problems in merging libraries which already
have their own library systemsRequires a greater degree of collaboration in
terms of cataloguing and indexing policiesRequires increase in network speed and
relibility
36Ayesha Abed Library
Which Model to Select?
• What are we trying to achieve?• What are our current members using?• What standards are implemented?• What services we like to offer?
37Ayesha Abed Library
Which Model to Select?
• Select Virtual Model ApproachMembers already have LIS Systems and OPACMembers uses different Systems, Catalogoing
Rules and StandardsDifficult to apply same standards and policiesTarget to support end users with greater
exposer and additional services
38Ayesha Abed Library
Which Model to Select?• Select Centralized Model ApproachMembers don’t have LIS Systems and Online
Accessible Catalogues.Target to Unify cataloguing Rules and
Standards.Target to minimize cost, and control
cataloguingAt the same time target to support end users
with greater exposer and additional servicesOwn the appropriate network (Speed and
reliability)39Ayesha Abed Library
