A New Generation of Technologies for Libraries and Information Centers
Marshall BreedingIndependent Consultant,Founder and Publisher, Library Technology Guideshttp://www.librarytechnology.org/http://twitter.com/mbreeding
25 March 2015 Special Libraries Association/Arabian Gulf Chapter
Description
Libraries and information centers in almost all sectors and geographic regions have experienced a fundamental shift where large proportions of electronic resources and digital materials complement, or even dominate, their print collections. This shift demands a response in the technical infrastructure for libraries so that they can effectively manage and provide access to these multi-faceted collections.
Breeding will describe the major changes in the realm of library automation, including the advent of a new generation of library services platforms which take a significant departure from the integrated library systems that previously dominated. A new generation of Web-scale index-based discovery services likewise provide powerful ways for library users to work with these complex and large-scale collections. These new genres of library systems take advantage of the scalability possible through cloud computing technologies and the extensibility and interoperability enabled through the services-oriented architecture.

Appropriate Automation Infrastructure
Current automation products out of step with current realities
Majority of library collection funds spent on electronic content
Majority of automation efforts support print activities
New discovery solutions help with access to e-content
Management of e-content continues with inadequate supporting infrastructure
Technology Shift
Client / Server > Web-based computing Beyond Web 2.0
Integration of social and academic identities and networks into core infrastructure
Local computing shifting to cloud platforms Application Service Provider offerings standard New expectations for multi-tenant software-as-a-
service Full spectrum of devices
full-scale / net book / tablet / mobile Mobile the current focus, but is only one example of
device and interface cycles
Strategic shift for Academic Libraries
Collection Shift from Print > Electronic + Digital E-journal transition largely complete Circulation of print collections slowing Large-scale investment in e-books
Technical infrastructure support: Need better tools for access to complex multi-
format collections Strong emphasis on digitizing local collections Demands for enterprise integration and
interoperability
New Metadata management WorlkFlows
Moving away from individual record-by-record creation Life cycle of metadata
Metadata follows the supply chain, improved and enhanced along the way as needed
Manage metadata in bulk when possible E-book collections
Highly shared metadata E-journal knowledge bases, e.g.
Great interest in moving toward semantic web and open linked data Path emerging for linked data in resource management and
discovery systems AACR2 > RDA MARC > BIBFRAME (http://bibframe.org/)
Software as a Service
Multi Tennant SaaS is the modern approach One copy of the code base serves multiple
sites Software functionality delivered entirely
through Web interfaces No workstation clients
Upgrades and fixes deployed universally Usually in small increments
Data as a service
SaaS provides opportunity for highly shared data models
Bibliographic knowledgebase: one globally shared copy that serves all libraries
Discovery indexes: article and object-level index for resource discovery
E-resource knowledge bases: shared authoritative repository of e-journal holdings
General opportunity to move away from library-by-library metadata management to globally shared workflows
Traditional model of Automation Oriented to Print collections Single Library System
Includes branches or divisional facilities Automation strategies often set when
capabilities of automation systems were limited
Institutional solo of collection management
Fragmented Library Management ILS for management of (mostly) print Duplicative financial transactions between ILS Acquisitions and
enterprise business systems (many shadow systems) Proxy and Authentication services E-book lending platform (multiple?) Interlibrary loan (borrowing and lending) Self-service and AMH infrastructure Electronic Resource Management PC Scheduling and print management Event scheduling Digital Collections Management platforms (CONTENTdm, DigiTool,
etc.) Discovery-layer services for broader access to library collections No effective integration services / interoperability among
disconnected systems, non-aligned metadata schemes
Reconceptualization of Automation Current organization of functionality based
on past assumptions Possible new organizing principles
Fulfillment = Circulation + ILL + DCB + e-commerce
Resource management = Cataloging + Acquisitions + Serials + ERM
Customer Relationship Management = Reference + Circulation + ILL (public services)
Enterprise Resource Planning = Acquisitions + Collection Development
Academic Libraries need a new model of library management
Not an Integrated Library System or Library Management System
The ILS was designed to help libraries manage print collections
Generally did not evolve to manage electronic collections
Other library automation products evolved: Electronic Resource Management Systems –
OpenURL Link Resolvers – Digital Library Management Systems -- Institutional Repositories
Integrated (for print) Library System

Comprehensive Resource Management
No longer sensible to use different software platforms for managing different types of library materials
ILS + ERM + OpenURL Resolver + Digital Asset management, etc. very inefficient model
Flexible platform capable of managing multiple type of library materials, multiple metadata formats, with appropriate workflows
Support for management of metadata in bulk Continuous lifecycle chain initiated before
publication
Library Services Platform
Library-specific software. Designed to help libraries automate their internal operations, manage collections, fulfillment requests, and deliver services
Services Service oriented architecture Exposes Web services and other API’s Facilitates the services libraries offer to their users
Platform General infrastructure for library automation Consistent with the concept of Platform as a Service Library programmers address the APIs of the platform to
extend functionality, create connections with other systems, dynamically interact with data
Library Services Platform Characteristics
Highly Shared data models Knowledgebase architecture Some may take hybrid approach to accommodate local
data stores Delivered through software as a service
Multi-tenant Unified workflows across formats and media Flexible metadata management
MARC – Dublin Core – VRA – MODS – ONIX Bibframe New structures not yet invented
Open APIs for extensibility and interoperability

Open Systems
Achieving openness has risen as the key driver behind library technology strategies
Libraries need to do more with their data Ability to improve customer experience and
operational efficiencies Demand for Interoperability Open source – full access to internal
program of the application Open API’s – expose programmatic
interfaces to data and functionality
Leveraging the Cloud
Moving legacy systems to hosted services provides some savings to individual institutions but does not result in dramatic transformation
Globally shared data and metadata models have the potential to achieve new levels of operational efficiencies and more powerful discovery and automation scenarios that improve the position of libraries overall.

The Evolution of Library Resource Discovery
Challenge: More integrated approach to information and service delivery
Library Web sites offer a menu of unconnected silos: Books: Library OPAC (ILS online catalog module) Search the Web site Articles: Aggregated content products, e-journal collections OpenURL linking services E-journal finding aids (Often managed by link resolver) Subject guides (e.g. Springshare LibGuides) Local digital collections

Aggregated Content packages
Challenge for Relevancy
Technically feasible to index hundreds of millions or billions of records through Lucene or SOLR
Difficult to order records in ways that make sense
Many fairly equivalent candidates returned for any given query
Must rely on use-based and social factors to improve relevancy rankings
Evaluating Index-based Discovery Services
Intense competition: how well the index covers the body of scholarly content stands as a key differentiator
Difficult to evaluate based on numbers of items indexed alone.
Important to ascertain now your library’s content packages are represented by the discovery service.
Important to know what items are indexed by citation and which are full text
Important to know whether the discovery service favors the content of any given publisher
A&I Content in Discovery Services
Will discovery services eventually become powerful enough to displace need for abstracting and indexing services?
Specialized vocabulary and other metadata make positive contributions to the discovery process
Specialized and scoped search methodologies
Researchers value this tools
Challenge for Relevancy
Technically feasible to index hundreds of millions or billions of records through Lucene or SOLR
Difficult to order records in ways that make sense
Many fairly equivalent candidates returned for any given query
Must rely on use-based and social factors to improve relevancy rankings
Objectivity: Does relevancy reflect bias or publisher preferences
Socially-powered discovery
Leverage use data to increase effectiveness of discovery
Usage data can identify important or popular materials to inform relevancy engines
Identify related materials that may not otherwise be uncovered through keyword matching
Be careful to avoid introducing bias loops
Challenges for Collection Coverage To work effectively, discovery services
need to cover comprehensively the body of content represented in library collections
What about publishers that do not participate?
Is content indexed at the citation or full-text level?
What are the restrictions for non-authenticated users?
How can libraries understand the differences in coverage among competing services?

Reassess expectations of Technology
Many previous assumptions no longer apply
Technology platforms scale infinitely No technical limits on how libraries share
technical infrastructure Cloud technologies enable new ways of
sharing metadata Build flexible systems not hardwired to
any given set of workflows
Reassess workflow and organizational options
ILS model shaped library organizations New Library Services Platforms may
enable new ways to organize how resource management and service delivery are performed
New technologies more able to support strategic priorities and initiatives
Time to engage
Transition to new technology models just underway
More transformative development than in previous phases of library automation
Opportunities to partner and collaborate Vendors want to create systems with long-
term value Question previously held assumptions
regarding the shape of technology infrastructure and services
Provide leadership in defining expectations
