Objectives
To review and define what electronic library and information resources are and consider– their features and functionality– their strengths and weaknesses– why you might want to use them
• To consider other electronic resources

Electronic library resources
• Any library or information resources that can be accessed electronically, e.g.– electronic journals– scholarly databases– electronic books– hybrid digital collections– Internet gateways and search engines
• Free or fee-based access

Electronic journal formats
• Full-text—whole journal available– Electronic version of print– Electronic only
• Partial full-text—selected articles only
• Table of contents/abstracts only

Why use e-journals?
• An up-to-date resource
• Convenience
• Extra features—e.g. search facilities, links to other databases, supplementary information
• Access to a wider range of material than might otherwise be available through your local library

Types of electronic resource• Academic
– Refereed journals– Review journals– Pre-prints– Bulletins
• Non-academic– Professional/trade journals– Magazines– Newspapers

Academic journals
• Example: African Crop Science Journal– www.inasp.org.uk/ajol/journals/acs/about.html
• Used to – disseminate research findings– find out about research being carried out
by others in your field– identify methodologies that might be
relevant to your own work
![Page 8: Electronic Library and Information Resources Introduction and overview](https://reader036.vdocuments.us/reader036/viewer/2022082917/55151e95550346c77d8b50da/html5/thumbnails/8.jpg)
Academic journals• Features
– written by researchers and experts– aimed at researchers and experts– articles always cite sources– peer reviewed
• Strengths/weaknesses– high-quality, reliable information– may be slow to be published due to lengthy review
process – often fee-based access
![Page 9: Electronic Library and Information Resources Introduction and overview](https://reader036.vdocuments.us/reader036/viewer/2022082917/55151e95550346c77d8b50da/html5/thumbnails/9.jpg)
Review journalsExample MathSciNet
– http://www.ams.org/mathscinet/search
Used to give an overview of the current literature in a specific research area or discipline
• Features– Give an overview of the current literature in a specific
research area or discipline– Titles usually contain ‘Review’, ‘Reviews’, Advances
in, ‘Current opinion in’, ‘Progress in’, ‘Trends in’ – Have already done much of the literature searching
for you

Bulletins• Example: Africa Research Bulletin
– http://www.africa-research-bulletin.com/
• Used for: – making announcements to a specific audience– up-to-date information in a very specific area
• Features – written by in-house staff, or staff writers – may be issued as required, sometimes intermittently – contain short reports
• Strengths/weaknesses– very up-to-date– standard very variable
![Page 11: Electronic Library and Information Resources Introduction and overview](https://reader036.vdocuments.us/reader036/viewer/2022082917/55151e95550346c77d8b50da/html5/thumbnails/11.jpg)
Pre-prints• Example: The Physics Eprint Archive
– http://xxx.lanl.gov/– now includes more than 70% of the current
physics literature world-wide
• Used to: – circumvent lengthy journals publication
process– solicit and provide informal prepublication
feedback on new ideas and findings
![Page 12: Electronic Library and Information Resources Introduction and overview](https://reader036.vdocuments.us/reader036/viewer/2022082917/55151e95550346c77d8b50da/html5/thumbnails/12.jpg)
Pre-prints• Features
– written by researchers for researchers– accessed online from a pre-print server
• Strengths/weaknesses– very up-to-date– allow rapid communication of results and
ideas and instant feedback– lacking the quality control process of a
peer-reviewed journal
![Page 13: Electronic Library and Information Resources Introduction and overview](https://reader036.vdocuments.us/reader036/viewer/2022082917/55151e95550346c77d8b50da/html5/thumbnails/13.jpg)
Non-academic resources• Professional/Trade journals
– Example: The Architects Journal http://www.ajplus.co.uk/
– Written by staff writers and experts in the field, aimed at members of a trade or industry, contain advertising, articles do not usually cite sources
– Good standard maintained by editorial board, ephemeral nature of the information
![Page 14: Electronic Library and Information Resources Introduction and overview](https://reader036.vdocuments.us/reader036/viewer/2022082917/55151e95550346c77d8b50da/html5/thumbnails/14.jpg)
Non-academic continued…• Magazines
– Entertainment, information about popular culture, product information
– Easy to read, entertaining, information is lightweight and not always reliable
• Newspapers– Up-to-the minute information, current affairs,
debate– Can be valuable sources of certain kinds of
formation but inherent problems of all newspapers
![Page 15: Electronic Library and Information Resources Introduction and overview](https://reader036.vdocuments.us/reader036/viewer/2022082917/55151e95550346c77d8b50da/html5/thumbnails/15.jpg)
Types of scholarly databases
• Bibliographic—references to published material
• Numeric—e.g. statistical tables
• Full text—complete publications
• Audio—collections of music
• Image—e.g. collections of slides
• Multimedia—audio-visual, animation etc
![Page 16: Electronic Library and Information Resources Introduction and overview](https://reader036.vdocuments.us/reader036/viewer/2022082917/55151e95550346c77d8b50da/html5/thumbnails/16.jpg)
Why use scholarly databases
• To search for information for a specific project or essay
• To provide an overview of research activity in a given area
• To keep up-to-date with a specific subject area through regular scanning
![Page 17: Electronic Library and Information Resources Introduction and overview](https://reader036.vdocuments.us/reader036/viewer/2022082917/55151e95550346c77d8b50da/html5/thumbnails/17.jpg)
Other e-resources
• E-books– e.g. http://etext.lib.virginia.edu/ebooks/
• Internet search engines– e.g. http://www.google.co.uk
• Internet gateways– e.g. http://www.inasp.info/health/

Summary• The range of electronic resources is
considerable and growing all the time• The type, quality and usefulness of
resources varies enormously (especially for academic users)
• There are both free and fee resources• New users should be made aware of the
differences, benefits and drawbacks of various kinds of resource
