WHAT IS THIS THING?

DeLIver is an experimental search system that you can access via the World Wide Web. It contains articles from engineering, physics and computer science published from 1995 to the present. DeLIver offers features not available in most other search systems. It allows you to search and view individual article parts (such as "just the figures" or "just the references"), it gives access to the full text of the article from your desktop (and printer). These are the journals available in this database .

DeLIver is the result of ongoing research by the NSF/DARPA/NASA Digital Libraries Initiative (DLI), at the University of Illinois at Urbana Champaign (UIUC).

USEFUL FEATURES

DeLIver allows you to search on and then view specific parts of the article. DeLIver allows you to "fine tune" a search and get more relevant results than you might with other search systems. For example, you can search for key words in figure captions and view the figure before deciding you want to read the article. Or you can search for articles written by researchers by MIT on a particular subject. You are able to do this because the articles are marked up in Standard Generalized Markup Language . This means the parts of the article (figures, tables, references, abstract, etc.) are tagged so that they can be searched.

DESKTOP ACCESS TO FULL TEXT OF ARTICLES

Searching for articles in DeLIver can be done via the World Wide Web using a standard web browser like Netscape, which is, of course, available for free. There are two ways to view the full text of articles. First, if you have a PC, you can view articles in the SGML format by downloading Panorama software (which is available for free.) A second alternative for Apple and UNIX users, as well as for PC users who prefer to view an image of the page as it actually appears in the print version, is using the freely available Adobe Acrobat Reader for those articles available in Portable Document Format. About 60% of the articles in this system are available in this format.

Whenever possible, we have provided links to papers listed in the reference sections of the articles contained in our database. If those referenced articles are also in our system, you can jump directly to the full text of those articles. When they are not a part of our system, whenever possible we have provided links to the abstract for that article from an indexing and abstracting service (INSPEC).

COPYRIGHT RESTRICTIONS

All DeLIver articles are copyrighted and all rights to them are reserved. Downloading, copying and printing of DeLIver materials is strictly limited by U.S. copyright law. Anyone who redistributes DeLIver's materials in any form or who otherwise makes use of these materials in any manner other than as allowed by the fair use provisions of U.S. copyright law may be held liable and accountable. (You make one copy for your own use and don't distribute it.)

WHO CAN USE IT?

Anyone associated with the University of Illinois at Urbana-Champaign (students, faculty and staff) can use DeLIver. Specifically, if you have an email address with @uiuc.edu, you will be able to access the system.

Users of the system will need particular software packages which are free to download. Searching for articles in DeLIver can be done via the World Wide Web using a standard web browser like Netscape. The articles in DeLIver are also available over the World Wide Web but you will need to download special software (for PCs only). Apple and UNIX users can use Adobe Acrobat Reader for DeLIver articles available in PDF (about 60% of the articles). Adobe Acrobat Reader will access articles available in PDF format (about 60% of the collection). These are both discussed further here.

COLLECTION COVERAGE

There are 54 journal titles in DeLIver from five (academic) publishers published from 1995 to the present. As stated above, these journals are from engineering, physics and computer science. Most issues of the journal are sent electronically from the publisher to UIUC and added to DeLIver before the print versions are available, but some titles will take a little longer. Journals are available only from 1995 or later because that is when the publishers began marking up their articles in SGML for the DLI project.
