ScienceDirect Database News: March/April 2008

Read about the latest on ScienceDirect Database:
* New functionality added to ScienceDirect to meet researchers' needs!
New to ScienceDirect are features that make the platform more user friendly and deliver better, clearer results in fewer clicks.

Preview tabs
Researchers like to quickly evaluate articles before reading them. They will find preview tabs that provide quick access to the important article assessment components: the abstract, figures / tables and references. These tabs are on the results page, the Table of Contents page and the Article page.

Reference information
Before, researchers have to scroll to the foot of articles to view reference information. Now it is possible for researchers to view reference information within the body of a paper when their cursor moves over a reference marker.

Article Toolbox
Once a researcher has evaluated and read an article, they often want to email it. A new article toolbox brings together all of the article-related functionality including "Cited By", "E-mail Article", "Save as Citation Alert", "Citation Feed", "Export Citation", Add to My Quick Links", "Add 2Collab" , etc., into one easy-to-find location. Researchers can now take further action quickly and easily with little extra effort.

New Navigation options
Looking for something specific? A new navigation pane on the left of the screen will make that easier by allowing you to refine results using four filters: “content type”; “source title”, “date” and “topics”. By enabling filtering you will be able to refine your search results without having to return to the search form.

Ratings
Researchers are interested to know how other experts rate articles they read. Due to be launched in phases over the coming months, the integration of article comments and ratings from Elsevier's social collaboration site, 2collab enables researchers to evaluate papers according to colleague-driven comments and ratings of articles right on the article page.
For more information visit the ScienceDirect Info site.

New Major Reference Works available on ScienceDirect

ScienceDirect Info site.

ScinceDirect database have received a number of new functionality since 2007 and I would like to say that all of them brought an improved look and feel. ScienceDirect has been updated with the latest technological innovation to help researchers find the information quickly and successfully.

Enjoy the latest improved features. Tell us how you feel about them. Make a comment.

Free Databases @ EbscoHost

In a post dated 1st of April (UKSG Serials E-News) I have mentioned that EbscoHost offers a number of free databases. After contacting Ebsco representatives, we are please to announce that these databases have been ADDED to the UJ Library EbscoHost list (find them at the end of the list).
* GreenFile
GreenFILE offers well-researched but accessible information covering all aspects of human impact on the environment. Its collection of scholarly, government and general-interest titles include content on the environmental effects of individuals, corporations and local/national governments, and what can be done on each level to minimize negative impact. Topics covered include global warming, green building, pollution, sustainable agriculture, renewable energy, recycling, and more. GreenFILE is multidisciplinary by nature and draws on the connections between the environment and a variety of disciplines such as agriculture, education, law, health and technology.The database provides indexing and abstracts for approximately 295,000 records, as well as Open Access full text for more than 4,600 records.
* Teacher Reference Center
Provides indexing and abstracts for more than 270 of the most popular teacher and administrator journals and magazines to assist professional educators.
I have done quick search on "science and research". The top references are:
- Professional development for computer-enhanced learning: a case study with science teachers.Research in Science & Technological Education; May2008, Vol. 26 Issue 1, p3-12
- Virtual teamwork: students studying about ethics in an online environment. Research in Science & Technological Education; May2008, Vol. 26 Issue 1, p13-29
- Teaching chemical bonding through jigsaw cooperative learning. Research in Science & Technological Education; May2008, Vol. 26 Issue 1, p47-57
The above journal is available in print & online - search through A-to-Z list ( the May 2008 issue is not yet available)
* Library, Information Science & Technology Abstracts (LISTA)
Library, Information Science & Technology Abstracts,(LISTA) indexes more than 690 periodicals, plus books, research reports and proceedings. Subject coverage includes librarianship, classification, cataloging, bibliometrics, online information retrieval, information management and more. Coverage in the database extends back as far as the mid-1960s. It is EBSCO Publishing’s intention to provide access to LISTA on a continual basis at http://www.libraryresearch.com/.
TIPS for searching:
As these databases provide bibliographic information it could be an added value if you search with some of the full-text databases, such as Academic Search Premier. Some of your results can be available full-text through that database.
DO YOU KNOW!
EbscoHost have added some new options for searching. If you are either in the Basic or Advanced Search Screens, you can select from the option "Specific Databases" a SUBJECT group databases to search:
- General/News databases
- Computer Science/Engineering Databases
- Earth/Environmental Databases
- Health Sciences Databases
- Life Sciences Databases
- EJS E-Journals
To summarise it, you can either search:
- selected individual databases
- selected 2 or more databases or
- the SUBJECT grouping from the individual databases available on EbscoHost.

Please note: This collection does not form part of the SpringerLink database subscription.

New interactive and intuitive tools encourage wider usage of ScienceDirect

More development-partner-tested features have been added to ScienceDirect. This new functionality, which is mirrored to researchers’ needs, will encourage greater use and exploitation of the wealth of information on ScienceDirect.
* The Related Articles feature automatically displays citation information and the abstract – including a link to the full text – of content relevant to the article being accessed. This improves the discoverability of information and makes it easier for users to find key information. Related Articles is enabled for every article accessed on ScienceDirect.

* To maximize search outcomes and eliminate unwanted results, the Fast Search & Transfer (FAST) spell check function has been integrated into ScienceDirect. The spell checker recognizes spelling errors using a built-in dictionary.

* As an added value to traditional abstracts, ScienceDirect is now indexing Graphical Abstracts of 30 chemistry titles. Important to chemistry researchers, Graphical Abstracts help to summarize the scope of a structure or reaction more succinctly than plain text. Graphical Abstracts will appear as the default display when browsing a table of contents from one of these journals on the journal homepage. On the search results the default display is the Article List with Full Abstracts or Graphical Abstracts as alternative display options.
Copyright permissions enabled through ScienceDirect
Subscribers can order copyright permissions directly through ScienceDirect now that Rightslink® has been selected for online copyright permissions. “Rightslink was the easy choice for improving customer responsiveness and accelerating turn-around times for copyright permissions,” said Helen Gainford, Elsevier’s Director of Global Rights, “Rightslink has a strong track record of success and we’ve been highly impressed with its ease-of-use and its ability to deliver quality customer service directly from our own content.”
