Using STNEasy to find articles
2
STNEasy is one front-end to search Chemical
Abstracts online
3
There are different ways to search but if the
focus is a chemical, its best to change the
category to Chemical Substances. If you know the
Registry number, you can use that tab.
4
Besides the default of word(s), you can choose to
search by chemical Name, CAS Registry number,
molecular formula, etc.

Notice that only one chemical is retrieved, and
that it displays As the Index Guide name, not
your search word (caffeine).
7
Display includes structure, registry number.

. Other chemical names (including caffeine), the
molecular formula, the number of references
youll find, and ways to restrict your references
to those on a certain aspect.

Here we choose to find chemistry references about
analytical studies of caffeine.
10
There are still a lot of references so we can
refine the search.
11
Two very useful refinements are the limit to
english language and to journal articles.
12
There are still too many references to look
through, so we can add another term to the search.

You can choose to see the most recent article
titles first, or

This tells you basic information about the
article. To find out if we have a copy in the
Pollak Library, search the OPAC for the journal
title.
17
The abstract can often give you good information
for example the levels of caffeine found in
caffeinated and decaffeinated coffee.
18
You can also find additional terms you could use
to do a different search, e.g. beverages. Notice
the reference to the volume and abstract number
in the printed Chemical Abstracts.

Each search costs money.
