Networked Information Resources Introduction & orientation

Resources Internal vs. external

Classification of networked resources By domains (gov, edu, com…) By accessibility (open or proprietary) By indexing methods (machine vs. human indexing) By publication status By intended audiences (expert vs. layperson) By access methods (push vs. pull; filtering vs. searching)

Accessible by the public Search engines Web directories Subject gateways/pathfinders Reference services Open access repositories OPAC (Open Public Access Catalog)

Search engines General purpose: teoma , Google, Ms. Dewey Meta-search engine: Dogpile, metacrawler Clustering search engine: vivisimo Wizard of OZ ChaCha (‘crowdsourcing’)

Web directories Google Directories Yahoo Directory Internet Public Library

Subject pathfinders/research guides A selective guide to information pertinent to the subject area: selection, description, classification Some examples: Subject pathfinder (NUS library) Social Science Information Gateways Organizing Medical Networked Information

Virtual references Virtual Reference Taiwan Ask a librarian service at Library of Congress

OPACs NTU library Union catalog (e.g. Meta Cat , NBINET)

Open access and electronic journals E-prints archives (Institution repository): 臺大機構典藏系統 E-prints in LIS, Los Alamos National Laboratory's physics preprint Pure electronic journals Digital Library Magazine Open Access Journal Directory

Institutional repository an online locus for collecting and preserving the intellectual of an institution, particularly a research institution. This would include materials such as research journal articles (before (preprints) and after (postprints) undergoing peer review, and digital versions of theses and dissertations, but it might also include other digital assets generated by normal academic life, such as administrative documents, course notes, or learning objects.

Not accessible by the pubic Proprietary databases Full text of serial titles (e.g. ELSEVIER ScienceDirect) Indexing and abstracting databases (e.g. LISA) Citation database: Web of Science , Scopus

Primary literature Works that make an original contribution to research Provides specifics on all aspects of the study being documented, from research methodology to scientific results and conclusions. In the forms of journal articles, conference proceedings, and dissertation/theses

Secondary literature Bibliographic databases: Web-based search interface to bibliographic records of primary and tertiary literature (indexes and abstracts services)

Tertiary literature Books: generally published at least 2-3 years after the research on which they are based. Provide synthesized evaluated information know at the time of publication

Impacts on librarianship Ownership/archiving vs. access Participation in knowledge production process Library-sponsored journals (e.g. highwire press); institutional repository End-user searching Information literacy; cognitive authority Novel knowledge discovery tool Data and text mining Blurring of institutional boundaries Library, archives, museum, media
