MARS Local Systems & Services Discovery Layer Discussion Forum

Description

An introduction to the genre of next-generation catalogs or discovery products.

Crowded Landscape of Information Providers on the Web

Lots of non-library Web destinations deliver content to library patrons Google Search / Google Scholar Amazon.com Wikipedia Ask.com

User expectations

Evolution of library collection discovery tools

Bound handwritten catalogs Card Catalogs Library online catalogs – OPACs Next-Gen Catalogs / Discovery interfaces Web-scale discovery services

Recommendation services

Web site as menu of search options

Disjointed approach to information and service delivery

Silos Prevail Books: Library OPAC (ILS module) Articles: Aggregated content products, e-journal

collections OpenURL linking services E-journal finding aids (Often managed by link

resolver) Local digital collections

ETDs, photos, rich media collections Metasearch engines

All searched separately

Lack of unified Web presence User’s don’t understand the distinctions

we make Catalog? Articles and Databases? Digital Library? Search our Site? Search interfaces based on content formats

or management applications Non-library Web sites are much more

unified

A simple vision

A single point of entry to all the content and services offered by the library

…but with precision, nuanced sophistication, and multiple dimensions

Search:

Web-scale discovery

Online Catalog vs. Discovery Layer

Online Catalog Interface

conventions from an earlier Web era

Scope: Tied to the ILS and its content domain

Discovery Layer Modern interface

elements Scope: aims to

address broad range of components that constitute library collections

Discovery Products

http://www.librarytechnology.org/

discovery.pl

Decoupled from ILS

Social discovery

Tags, user-supplied ratings and reviews Leverage social networking interactions to

assist readers in identifying interesting materials: BiblioCommons

Leverage use data for a recommendation service of scholarly content based on link resolver data: Ex Libris bX service

Deep indexing Metadata can no longer serve as the only basis for

discovery Increasing opportunities to search the full contents

Google Library Print, Google Publisher, Open Content Alliance, government publications, etc.

High-quality metadata will improve search precision Commercial search providers already offer “search

inside the book” and searching across the full text of large book collections

Important transition to full-text book search beginning in library projects HathiTrust indexing 6 million volumes Must become a routine component of library discovery

Deep search highly improved by high-quality metadata

Discovery product Trend

Initial products focused on technology AquaBrowser, Endeca, Primo, Encore, VUfind Mostly locally-installed software

Current phase focused on integrated access to both local content and remote articles to deliver Web-scale discovery. Examples: Summon (Serials Solutions) WorldCat Local (OCLC) EBSCO Discovery Service (EBSCO) Primo Central Encore Synergy

Beyond Federated search

Federated Search / Metasearch use real-time queries against multiple information targets

No centralized index – presentation of dynamic results

Shallow results -- only a few results initially fetched from each target

Difficult to calculate relevancy Performance challenges

Beyond local discovery interfaces

Pre-populated indexes Web-scale

Exploits the full depth and breadth of library collections

Beyond the bounds of the local library’s collection

Targets the universe of objective, vetted library content

Pre-populated discovery services

New-generation interface Harvested local content

ILS metadata Institutional repositories, ETDs, Digital Collection

platforms Vendor-supplied indexes of library content

E-journals, databases, e-books Full-text and metadata corresponding to e-content

subscriptions Book collections beyond local library collections

Includes full-text indexing to the fullest extent possible
