5Subject Directories Search Engines
- Subject Directories are a lot like phone books
for the WWW. Look up Web sites by subject or
name. - Most allow you to browse by subject or search
using keywords. - Ipl2 (http//www.ipl2.org/ )
- Yahoo! ( http//www.yahoo.com/ )
- About.com ( http//www.about.com/ )
6Subject Directories Search Engines
- Search engines are tools that allow you to search
an index to the text that appears on Web pages. - The index is only to pages it has found.
- The index could be hours, days or months old.
There is normally no way to tell. - You type words into the search box and the
engine returns a list of pages that contain those
words.
7Subject Directories Search Engines
- You could just type in words without thinking
much and often you will get good results. But
sometimes its good to have a little madness to
your method. - How to Search with a Search Engine
- Think about your question.
- Imagine a Web page that will contain your answer.
- Type words and/or phrases (in ) that most
likely would appear on your imaginary page into
the search box. - Review results and modify search.
8Subject Directories Search Engines
- Google ( http//www.google.com/ )
- Bing ( http//www.bing.com)
- Teoma ( http//www.teoma.com/ )
- Like with subject directories, every search
engine is owned and controlled by a different
organization and operates differently.
9Subject Directories Search Engines
- Search engines have more pages (billions vs.
millions), but subject directories tend to have
only important sites. This is because real people
make decisions about what goes into a subject
directory.
10Search Tips
- Use unique search terms
- Use synonyms
- Put words in different order
- Put phrases in quotation marks
- Search online versions of print sources
11Search Tips (Contd.)
- Use lower case (and alternative) spellings of
search terms - Limit your searches (images, video, MP3 files)
- Use different search engines
- Read the help section or Advanced Search to
focus your search
12Librarians The Best Search Tools
- Why use a reference librarian?
- Librarians go to graduate school to learn to do
their jobs. - Librarians have years of experience searching and
helping people search for information every day. - Youve already paid your taxes for the library,
so why not use it?
13Meta Search Engines
- Submits your search to multiple search engines
and displays the results for you. - Search engines only search their own index, but
you may get better coverage if you search across
more than one. - Dogpile ( http//www.dogpile.com/ )
- Vivisimo ( http//www.vivisimo.com/ )
14Subject Specific Directories
- This is like a subject directory except that it
is limited to a specific subject, type of
information, group of people, etc. - Artcyclopedia (http//www.artcyclopedia.com/ )
- Yahoo! Get Local ( http//cityguides.local.yahoo.c
om/ ) - FirstGov ( http//www.firstgov.gov/ )
- HealthFinder ( http//www.healthfinder.gov/ )
15The Invisible Web
- There are many parts of the Web that for various
reasons are not searchable by search engines.
These parts altogether are referred to as the
Invisible Web. - Included in the Invisible Web are the librarys
many subscription databases. - http//www.elmhurstpubliclibrary.org/

17Ask the Expert Services
- Many Web sites have people who have subject
expertise answer questions as a service to their
users. - One place to find these services is at the
Virtual Reference Desk AskALocator

19Web Rings
- Some Web sites choose to associate with each
other by linking to one another. An organized
fashion of doing this is by joining a Web ring. - A directory of Web rings is at
- http//dir.webring.com/
- Amateur Photography Ring
- http//hub.webring.org/hub/amateurphoto
- Crafts Connection Ring
- http//a.webring.com/hub?ringcraftsites
20Mailing Lists Discussion Groups
- Mailing lists, often called LISTSERVs, can be
either newsletters or open discussion forums that
occur through e-mail. In order to use a mailing
list, you have to register with it. They are
available for all sorts of subjects. - To find a mailing list on a subject of interest
to you, check out - http//www.lsoft.com/catalist.html
21Mailing Lists Discussion Groups
- Discussion groups work much like mailing lists,
except that they are not used through e-mail.
Discussion groups are accessed through the Web or
via special programs for viewing the messages. - To find out more about discussion groups and find
ones of interest to you see - http//groups.google.com/

32Additional Web Features
- The Web on a basic level is simply hypertext, but
the modern Web has been enhanced with many
features. - Animation, Video, Sound Plug-ins
- Frames
- Forms
- Pop-up Windows
- Fake Messages
33Animations, Video, Sound Plug-ins
- Browsers are designed to display Web pages.
Anything beyond displaying Web pages will require
that the browser work with another program. In
some cases the browser itself is enhanced by a
program, called a plug-in. In other cases, the
browser simply uses a program that already exists
on the computer. - A few examples of plug-ins are
- Adobe Acrobat Reader
- Macromedia Flash Player
34Frames
- Some pages are actually more than one page
combined together. These pages are called frames.
35Forms
- When you want to send information to the author
of a Web site, you use forms. The Librarys
E-mail Contact Us form is one example of a form.
Search engines are another example of forms.
36Pop-up Windows
- Having new windows pop up over your browser is a
very common occurrence when surfing the Web.
Sometimes the pop-up windows are important
information and other times they are
advertisements. - The solution to them is pop-up blocking software,
but that sometimes blocks good pop-ups.
37Fake Messages
- Another common occurrence with pop-ups is a when
you get a message that appears to be an important
system message from your computer. - Note the title bar of the message.
38Web Safety Security
- Personal Privacy
- Computer Security
- Personal Safety
39Personal Privacy
- Cookies
- Adware Spyware
- Secure Socket Layer (SSL)
40Cookies
Cookies are a way for a Web site to remember that
youve visited before. The site leaves a piece
of data on your computer that only they can read
and then when they see that data again they know
it is from the same computer.
41Cookies (contd)
- Used to your advantage
- Would you be interested in a book about fish?
- Welcome back, Mrs. Smith!
- However, cookies can also be used to track your
behavior online.
42Cookies (contd)
You can delete or limit your cookies.
43Adware and Spyware
- Software installed on your computer than monitors
what you do (programs you run, keys you type and
sites you visit). - Can be as benign as monitoring your behavior and
focusing ads at you based on it. - Can be as dangerous as collecting your personal
information and sending it to others.
44Secure Socket Layer (SSL)
Encrypts data you send over the web to protect
your privacy. When you are using SSL the Web
address should start with https instead of
http. Also, the browser will display a lock (
) on the bottom right corner. This is
initiated by the Web site.
45Computer Security
- Viruses, Worms Trojan Horses
- Adware Spyware
- Antivirus programs
- Firewalls
46Viruses, Worms Trojan Horses
Viruses attached to a program or file and
replicate themselves. Worms Programs that run
independent of other programs and damage your
computer. Trojan Horses Once they get into
your computer they let outsiders in.
47Adware Spyware
Hostile versions of adware and spyware, often
called malware, are generally considered to be
viruses. Many spyware programs dont do much
more damage than slow your computer down.
48Antivirus Programs
You can buy programs that will run on your
computer and protect it from known viruses. This
software must be regularly updated with new
viruses.
49Firewalls
Blocks people and programs from entering your
computer through networks or the Internet without
your permission. Can be software running on your
computer or a piece of hardware, called a router.
