Chemistry 111: Exercise 1
INTRODUCTION TO THE SCIENTIFIC LITERATURE
• Read each section of the assignment and
the questions. Then use the guide to help
find the answers.
• If you have problems please ask at the
Evans Library Ask Us Desk, Chat with us
at http://guides.library.tamu.edu/askus or
call 979-845-5741

1.1 Use LibCat to find a book or government document on your assigned
pollutant. Write the title of the publication in Part 1.1. If there are too
many items listed, narrow the subject or keyword search with terms like
pollution or environment. The truncation symbol ? can be used to help
broaden the search.
Example search: Keyword = benzene AND pollut?
LibCat searches generally rank results in a relevancy order; use the pull-
down menu to change to a ranking by date to examine recent works.
Part 1. Finding Technical Books and Government Documents Using LibCat

1.2 Obtain a Location Guide from the Evans Library Ask Us Desk or
other service desk. Look for your book or document in the library, and
circle its location on the Location Guide to show where you found the
item.
Example: QD’s on 4th floor, or government documents on the
5th floor of the Sterling C. Evans Library Annex.
Attach the Location Guide and a print out of the LibCat record for the
item to the Data Reduction and Analysis worksheet. If the item is
electronic and if there is no call number associated with the
item then choose another publication.
1.3 Use the LibCat record for the publication recorded in part 1.1 to
answer the following questions on the worksheet form: Was the item
checked out, or on the shelf? What is the Call Number? What is
the format?

Questions for Part 1
Part 1.1 Name of Publication
Part 1.2 Attach copy of the LibCat record
Part 1.3 Was the item checked out, or on the shelf? What is the call number?
Format—Circle the correct format(s): Print, Electronic, Microform/Microfiche

1. Go to the Libraries’ homepage:
library.tamu.edu
Then click the LibCat link.
Library Module 1: Technical Books and Government Documents

2. Click on Advanced Search

3. Enter the search terms. Use the truncation
symbol ? to include words that start with “pollut”,
such as pollution, polluting, pollutant, etc.
4. Click Search

5. Change “Sort By” to “Publish Date.” This will
sort the results beginning with the most recent.
6. Click on the title of the
item to see the record.

LibCat Record for an Individual Item
NOTE: This government document is available online
and in microfiche. Information about the
microfiche version is shown below.
7. Note location,
call number,
and status
8. Click the link to find the
location in the library.

Part 2. Tools for Searching the Professional Journal Literature
For this exercise, you will be using one or more of the major databases
often used by undergraduates. These databases allow you to quickly
locate articles on a topic. Using a database is much quicker than
searching individual journals.
When communicating with other professionals, you need to give them all
the information they will need to find the article for themselves. Proper
citation form becomes important. The following exercises will show you
the way to arrange the information that identifies the book or journal
article in proper citation form.

2.1 Use Web of Science, Environmental Sciences & Pollution Management,
or Academic Search Complete to find a scientific article published in the last five
years on your assigned pollutant. Please note that you can limit by date in these
databases. You can also limit by type of material: book, articles, and conference
proceedings. You will limit your search to articles.
Example keyword search: benzene and pollut* (notice that for this database the
truncation symbol has changed to an *.)
Print the first page of the article, if the full text is available online. If not, print the
citation, with abstract if available, from the database. Attach your printout to the
back of this page. If the library does not subscribe to the online version of the
journal, use LibCat to determine if the print version of the article is available on
campus. Be sure to verify that the library owns the particular volume by looking at
the list of volumes found at the bottom of the LibCat record. If the University
Libraries subscribe to the journal, list the call number.
2.2 Provide the bibliographic citation you would need to cite the article in a
paper—journal articles should be cited using the following format:
Authors separated by semicolons, Article Title, Journal name in italics,
Year in bold, Volume in italics, Page numbers.
Example: E. J. Mawk; M. Hyman; M. W. Rowe. Re-examination of Ancient DNA in
Texas Rock Paintings. Journal of Archaeological Science 2002, 29, 301-306.

Part 2.1 Attach the first page of your article or list call #
Part 2.2 Write the bibliographic citation

an “*” as a truncation symbol where appropriate. Using pollut*
will retrieve pollutant, polluted, etc.
7. Limit by language
8. Limit by publication
date range
9. Limit the search to just the
Science Citation Index. This
will help focus the search to
science journal articles
10. Click Search

the full-text of the article and print the first page
for your assignment.

Part 3. Governmental Information Sources: EPA and NLM
3.1 Using ChemIDplus or IRIS, find the CASRN (Chemical Abstracts Service Registry
Number) and molecular formula for the assigned pollutant.
3.2 Use ChemIDplus to find two other names for the assigned pollutant, including the
systematic name.
3.3 Use IRIS, ChemIDplus, or other sources identified in this assignment to determine
where this compound or element primarily occurs as a pollutant. Examples: air,
water, food, etc.
3.4 Does ChemIDplus include a table of toxicity values for your pollutant?
3.5 Use any source, including the EPA site (http://www.epa.gov/OCEPAterms/lterms.html),
to find brief definitions for the following terms used in toxicity studies and
regulations; LD, LD50, LC, LC50, LOAEL.

Part 6. Learning How This Pollutant Affects or Might be Handled
by Professionals in Your Major Area of Study
6.1 Use the Subject Guides link on the university libraries homepage to find the
subject guide for your major or a related field (http://guides.library.tamu.edu/).
Select one of the databases listed. Identify the name of the subject guide, the
name of the database, and your major.
6.2 Find an article in the database that addresses how professionals in your
chosen field deal with or are affected by the pollutant, or if the particular
pollutant isn’t listed, by pollution in general. A business major, for example,
might search a business database to find an article on the financial impact of
pollution abatement for the chemical. A liberal arts major could use newspaper
databases to determine how the media has covered pollution caused by the
chemical. Consider terms such as public health, occupational exposure, and
risk to workers. Write a short summary of your findings and provide the
citation to the article. Write no more than half a page. If you do not find material
in 20 minutes, then please ask for help. Include the citation.

Part 6.1 Name of the subject guide
Name of the database
Major
Part 6.2 Attach the article summary (typed) with the appropriate citation.
