ILS, the Next Generation: ERMS, Metasearch, Link Resolver, Portals, Digital Asset Management – Oh My!

Next Generation: Modularity “ILSes should think in
terms of linking rather than building”
Decoupling discovery and inventory management functions
Standards E-resource
management systems

What Did Users Say They Want? (2002)
•Faculty and students do more work and study away from campus
•Loyal to the library, but library is only one element in complex information structure
•Print still important, but almost half of undergraduates say they rely exclusively or almost exclusively on electronic materials
•Seamless linking from one information object to another is expected
•Fast forward to 2006: these trends many times stronger!
Do you use electronic sources all of the time, most of the time, some of the time, or none of the
time?

Toward a New Library Information Space
Methods and tools Web-accessible lists +
catalogs Federated searching Reference linking
(OpenURL) Portals E-resource
management systems Digital asset
management systems
Objectives Integrate access to all
library resources (print, archives, digital, e-)
Simplify digital and e-resource management (lower costs AND improve service)
Become visible in the user’s environment (i.e., on open Web, on course pages, etc.)
September 2006 Calhoun 5
Levels of Access Web-accessible lists
Browsing Searching Both
Online catalog Federated searching Reference linking
September 2006 Calhoun 6
Web-Accessible Lists (Database Driven, Searchable)
September 2006 Calhoun 7
Catalog Records for E-Resources

What’s Federated Searching (Metasearch)? Helps users more easily discover what
resources are available Provides searching of many resources at
the same time Unifies search results Links search results to full text Authenticates and authorizes or blocks
user access
September 2006 Calhoun 9
Metasearch: what’s missing Response time comparatively slow Practical limits to number of databases that can be:
Configured for searching Searched at once
Incomplete search results (also due to practical limits) Lack of control over what is returned in search result sets Order of search results displays not as useful as they
should be Other limitations on what can (or can’t) be displayed
September 2006 Calhoun 10
Hope for Metasearch NISO Metasearch Initiative: http://www.niso.org/committees/MS_initiative.html
“Metasearch services rely on a variety of approaches to search and retrieval including open standards (such as NISO's Z39.50), proprietary API's, and screen scraping. However, the absence of widely supported standards, best practices, and tools makes the metasearch environment less efficient for the system provider, the content provider, and ultimately the end-user.”
Google Scholar: Forget Metasearch?
Find It At Cornell
You can do this for articles too

Reference Linking Users expect fully linked information
environment Partnerships between content
providers, database producers, and library system vendors, utilities …
September 2006 Calhoun 13
Limitations of Reference Linking Incomplete or inaccurate metadata from source; can’t
match knowledge base Knowledge base is incorrect or out of date Metadata alright but doesn’t match target Varied application of citation standards; non-use of citation
standards Library has full text for journal but not the volume/issue
the user wants Full text availability lags behind citation availability And on and on

Prediction Of the two,
OpenURL will be the core technology, not metasearch

Outward Integration
“Integration should be outward rather than inward, with libraries seeking to use their components in new ways”
--Interviewee for LC report on future of the catalog
September 2006 Calhoun 18
Longer Term Vision Switch users from where they find things to library-
managed collections of all kinds Local catalog one link in a chain of services, one repository
managed by the library More coherent and comprehensive scholarly information
systems, perhaps by discipline Infrastructure to permit global discovery and delivery of
information among open, loosely-coupled systems Critical mass of digitized publications and special
collections online Many starting points on the Web leading to many types of
scholarly information objects

Find It on Google,* Get It from My Library Open WorldCat RedLight Green Google Scholar Google Book Search Google Library Project Million Book Project Open Content Alliance EU project E-books and journals
*The word "google" was first used in the 1927 Little Rascals silent film"Dog Heaven", used to refer to a having a drink of water. en.wikipedia.org/wiki/Google_(verb)

Intermediate Vision Shared OPACs: begin to aggregate
discovery function for books, serials, and their e-counterparts
Metasearch for e-journal articles Reference linking ubiquitous Draw on the local catalog’s strongest suit:
support for inventory control and delivery Larger scale collaboration on collection
development/resource sharing, storage, preservation
September 2006 Calhoun 21
Intermediate Vision, 2 Greater use of Web services to link in and
out, tie applications together Start to build bigger scholarly information
environments—with libraries playing a role—to aggregate more of the expanding universe of scholarly digital assets
Metadata and outreach skills = strategic assets
September 2006 Calhoun 22
Intermediate Vision, 3 Beginning of the era of special collections Aggregate discovery of digital collections More emphasis on visual resources More collaboration with faculty on digital
assets Rise of best practices for digital asset
management Digital collection delivery platforms will
continue to proliferate

Good Advice for Digital Librarians
At this stage, no new effort should be undertaken without a sense of how it will be merged with other existing collections and where the resources for long-term maintenance will come from.
