… answer not simple

Library collections in the digital age are changing to new forms AND functionspart is evolution

from old to newpart is revolution

very, very new

Effects on libraries are profound and large

Foreword: Where did it all come from?

Emergence of the digital information systems

online bibliographic & numeric databases for searching

online catalog followed byelectronic reference databases full-text digital articles and

journals and digital collectionsAND: new forms of scholarly

communication, e-publications, &e-archives in many fields

All on networks, and most distributed (stored) all over

Forces shaping new collection concepts

Changing nature of objects for digital & hybrid libraries

New digital technical & networked environment

Evolving economic models away from ownership

Many possibilities for linkages

Real sharing possibilitiesRevolution in access meansChanges in users’

information seeking, needs, & publishing

Traditional concept of a ‘collection’

From library point of viewsum total of library materials that

make a holding of a particular library

organized for use

Major characteristics:objects: (documents) tangible,

have a physical presence & location

economics: ownership of physical object, but not content

location: brick & mortaraccess: tangible, physical, direct

Broadening of the traditional concept

Collectiona set of information resources

selected, accumulated & developed for use by a user community or communities

Major characteristics:objects: tangible & intangible,

have a physical presence, but also other media

economics: ownership, but also of access, sharing & cooperation

location: mostly in-houseaccess: direct, but also remote

Digital collection - still broader concept

A set of digital & multimedia information resources

selected and/or created following defined criteria & policies

for a defined community of users but not necessarily accumulated

owned, licensed, or freely accessed with possibility of sharing - consortia distributed as to location adapted for networked environment included access & search tools parts with specified access rights included portals to other collections

Still evolving, not yet settled

Major characteristics: DL objects

A variety of intangible objectsFrom outside: e-publications, e-

journals, e-books, multimediaFrom inside: objects, collections,

databases created within library1. tangible objects selected from traditional

collections & then digitized & organized 2. objects borne digital, new resources

Gateways, portals, directories links selected, organized, evaluated, vertical portals (vortals) in specialized

areas, subjects, topics digital bridges to distributed resources

Characteristics: DL economics

Economics of ownership vs. economics of accessownership declining a lot

counting what owned not relevantreplaced by access

licensing to e-publications time dependent; many variations

sharing costs & access through consortia & similar arrangements

charging distributed, subsidized

Also entering into economics of e-publishing - digitizing

Characteristics: DL location

Could be on in-house network

More often, distributed to large number of locationscollection becomes collectionse-publishers providing ‘shelf

space’ to licensed collectionslittle or no control over

distributed resourcesPersistence: a BIG issueDependent on the Internet

& networked arrangements

Characteristics: DL access

Access arrangements are an integral part of collection information retrieval for searching

search engines often provided with licensed collections

navigation, browsing arrangementsextended functionality

Different levels of accesssubject to policy & licensepartial universally open full dependent on belonging to a

defined communityUsers usually self-directed

Approaches to collection decisions

Collection developmentacquisitions, selection, and

collection buildingbased on criteria & user

needsCollection management

collection development plus a broader range of policy, planning, analysis, and cooperative activities

with digital collections plus close involvement of access

Collection management

Number of areas & activities theory and practice of collection

policy development selection, acquisition, licensesmaterials budget allocation,collection analysis,collection use and user studies, staff training & organization preservation, persistencecooperative collection

development; sharing resourcesmanagement of collection space:

from physical to virtual

Selection criteria for electronic resources

Many traditional criteria remain but with new interpretations

A number of new criteria have emerged specific to digital nature of resources & access

many can be found on the Web

Judicial Judicial & trusted selection: trusted selection: a ka key value-added contribution

by library trust extends to digital collectionsmakes all the difference between

a library & other collections

Specific selection criteria

what & why? - documents, objects

content? purpose? scope? viewpoint?

by whom? - creators, authors, institutions identity? authority? credibility?

reputation? qualification? refereeing?

where? - affiliation, connections identity? overt? covert?

authority? credibility? reputation?

criteria ...

for whom? - orientationintended audience? needs

satisfied? fit with user community?

when? - timelinesscurrency? up-to-date?

revisions? persistence estimate?

how? - treatment, coverageaccuracy? credibility?

objectivity? style? clarity? organization? usability?

criteria ...

in what way? - presentationformat? layout? interface?

search capabilities? access?

how much? - economics

effort? price? cost-benefits? license? sharing?

in comparison to? - competitionother similar resources?

Web sites & cognitive authority

Assigning credibility to Web information a BIG problemsometimes even attribution

difficult identity? reputation? qualifications?

Need to carefully asses:document, author, institution

& affiliation on criteria of: authority; accuracy; currency;

objectivity; coverageLibraries provide an important

service in criteria development & assessments of Web sites

Facing: Realities within

Assortment of forces in playeconomic constraints

“libraries are struggling to maintain two libraries: a physical library & a digital library, with resources that are inadequate for both.”

difficulties in finding, training personnel with new competencies

balancing the demands of print and digital materials

difficulty in assessment of many digital resources

difficulty in assuring persistence for many here today, gone tomorrow

© Tefko Saracevic, Rutgers University 20

Facing:Realities without

Dramatic changes in scholarly publishing & communication

technical advances in digitization are truly revolutionizing the way scholarly information is published, organized, maintained, distributed, & accessed - new world emerging

Increased competition in provision of various library-like

services by non-library institutions & commercial organizations

Ever changing technologyhardware, software, networksgetting & keeping competencies

Consortia

Library cooperatives emerging as answer to digital collection problemseconomics of scale kick inpower in negotiation for

licensesenable sharing of collectionsregulate access to their

communitiesLibraries forced to working

together by economic realities & technological possibilities

Issues for digital collections

Traditions long tested in collection development & management:What standards, values &

approaches to keep? Modify?What new standards to develop?

Location of digital collections: Where? does it matter?

Boundaries: where are they? Forward links - collection? directory? Networks: a gigantic collection?

then, is a particular ‘collection’ meaningful or not to users?

Issues ...

Creation: How and where to become

creator of digital collections?Lines between libraries &

publishers blurring

Access: How to integrate with

collection?How to provide, safeguard, &

protect access?Economics:

Where and how to adjust?Trade-off? Sharing? Licensing?

Conclusions

The concept of library ‘collection’ has changed dramatically & will change even moreincludes many problems -

should be viewed as opportunities for libraries to innovate & lead

How radically will collection management change in the next five or ten years?

How is it changing on a day-to-day basis right now?
