Most electronic journal subscriptions are authorized by IP address.
For off-campus users, Lehigh has a Proxy Server. (Almost) all of
Lehigh's electronic journals are linked directly from ASA, the online catalog.
The exceptions require individual IDs/passwords; the ASA link routes users
to a page with the appropriate information and link.

Chemical Abstracts is one of the world's premier abstracting services.
It covers over 16,000 publications (journals, conferences, technical reports,
dissertations, patents) in many languages and many disciplines. Chemistry
predominates, but biology, medicine, engineering disciplines are also well
covered. It is a highly structured database (the "user manual" itself
is two thick volumes), with author, keyword, subject term, chemical name,
chemical structure, formula, registry number, and patent indexes.
To properly use it takes years of practice, which discourages many users,
to the point where they don't even bother to try. Since this leads
to poor research, a number of solutions have been created. One of
those is simply to make it an electronic service; another is to provide
an array of interfaces. Lehigh has

INSPEC is the premier database for physics, electrical/electronics, and computer science/engineering. There is a good deal of overlap in publication coverage between Chemical Abstracts and INSPEC, but the treatment is different. Indexing terminology is the most obvious difference, but there is also more emphasis on specific property data in INSPEC than in CA.
The SCI is an entirely different kind of literature indexing
service. Most services take a subject approach; SCI chases
footnotes. The premise behind the SCI is the good "seed" paper.
Researchers find a good paper on their topic, then trace the references
in that paper to other relevant publications, then trace the references
in those publications... The flaw with that approach is that it always
leads to earlier material, which eventually becomes too old to be
useful. The SCI provides a system for tracing footnotes into
the future. Unlike other indexing services, the older years
of SCI are often just a useful as the current ones. Lehigh
has the SCI in paper from 1955-1995 and on CD-ROM from 1991 to date.
Both
are only available in the Fairchild/Martindale Library (main floor).
The search techniques described here are specific to the CD-ROM version,
but the technique is the same for the paper volumes.
