If you're looking for a job and dread
the line at Career Planning and Place-
ment, a job guide is now available on the
Internet.
CP&P has published an updated and
expanded version of "Job Search and
Employment Opportunities: Best Bets
from the Net," an online job guide. With
"Best Bets," students can look for job
postings and career information through
the Internet.
"Best Bets" was designed by Philip
Ray and Bradley Taylor, two graduate
students of the School of Information
and Library Studies. Taylor said it was
developed as part of a course require-
ment.
Taylor said the pair chose to create
an employment guide in response to the
surplus of job-related information on the
Internet that is not well-organized.
"It is to help people identify the best
of these sources in a subject area and
there are also written descriptions so
people.have a sense of what kind of in-
formation is available, so they don't have
to spend their time looking at sites that
are not useful," Taylor said. "It shortens
the job search process."
Lou Rosenfeld, a doctoral student of
the School of Information and Library
Studies, was the instructor of the Internet
course.
"The assignment was to create a
guide to information available via the
Internet. The information had to be on
one subject and their subject was em-
ployment," Rosenfeld said.
While creating "Best Bets," CP&P
played the role of providing guidance
and expertise to Ray and Taylor.
"(CP&P) was really glad to have this
guide," Taylor said. "They want a guide*
that can help students in Michigan."
"Best Bets" debuted early last No-
vember and has since been updated three
times. Taylor said there are over 100,000
people using the guide.
Jeanne Miller, a CP&P librarian, said
"Best Bets" is one of the top three
heavily used resource guides on the In-
ternet.
Although "Best Bets" can help stu-
dents conduct a find employment, it is
not intended to replace the traditional job
search.
"It is not a transition from one
method of job search to another method.
It is a new job search tool that people can
use," Miller said.
Miller also said that the guide is
aimed at a specific audience. "This guide
is directed at college graduates looking
for entry-level jobs," she said.
"It gives people another place to look
for jobs. It is a natural extension of the
process of job search," Taylor said. "The
advantage of using it is the rate in which
information can be updated is faster than
print-based resources."
