I am an ordinary graphic with no hotlink.
Use the scrollbar at the right side of this window to move up or down the page >
(click on the up arrow to move up or click on the down arrow to move down).

The purpose of this tutorial program is to allow you to become familiar with the World Wide Web (WWW or Web for short) and learn how to find information on the internet that is of interest to you. In this short session you will learn how to do the following things:
The very first thing to learn, for situations such as this, is how to get back here to your starting page. To do this at any time and from any other location, just click on the button at the top of this window called "Back". Each time you click on this button you will move back on step on the path you have taken until you find yourself back at your starting page. (The button called "Home" will take you back directly to the home location which is the page you were on when you first logged on to Netscape)
A page on the Web is a continuous document which may be very long, filling many computer screens. You can move around on this page or any other page by using the scroll bar on the right side of the window. Just click on the down arrow to move down the page and the up arrow to move up. Also you can use the "page up" or "page down" keys on the keyboard to move up or down by one full screen. For smaller movements you use the the up arrow key to move up by one line or down arrow key to move down by one line. The "end" key on the keyboard will usually take you directly to the bottom of the page and the "home" key on the keyboard will usually take you directly to the top of the page. Try these keys now to see how they work.
Another way of navigating is by using the "Back" button on the top of the
screen. Each time you click on this button you will go back to the previous
link you have used.
Click on the "Back" button now three times to repeat
the path you just followed in the reverse order and return back here.
The "Forward" button on the top of the screen acts in a similar way except
it takes you in the opposite direction from the "Back" button.
Click on the "Forward" button now three times to repeat same path in
the forward direction and return back here.
You may have noticed that the "Back" and "Forward" buttons have the important advantage of bringing you back to the same place on a page that you started from. Other buttons, such as the "Home" button, usually bring you back to the top of the page.
One more useful navigation tool is the "Go" menu at the top of the screen.
If you click on this and hold the mouse button down you will see all the
steps in the path you have recently followed and can go directly to any
location by selecting it and releasing the mouse button. The most recent
location is at the top of the list and the current location is indicated
by a checkmark.
Try it now to go to another location such as
"WPL MAC Tutorial Page 3" and then return here by selecting "WPL MAC Tutorial".
Note that the first time you select a hotlink it will change color (as will all other hotlinks to that same location). The color change is a useful navigation aid to help you keep track of where you have been, but does not affect the operation of the hotlink in any way.
Graphics can also serve as hotlinks. There are two different ways of using graphics for hotlinks as illustrated by the examples below:
I am an ordinary graphic with no hotlink.
and I am the same graphic with an ordinary hotlink!
and I am the same graphic with a fancy imagemap!
The graphic in the center has a hotlink which behaves in a similar manner to the text hotlink you used before - namely when you click on it it performs one single action. The graphic on the bottom is called an "imagemap" and is much more versatile. It detects exactly where you click in the image and can be programmed to take many different actions according to that location. For example, you could get a different action by clicking on one eye or the other or the mouth etc. This particular graphic is 32 pixels square and so could be programmed to take up to 32X32=1024 different actions depending on the exact position of the cursor where you click! (Note that this graphic has been programmed only to bring you back to the top of this page.)
Easy! Just select all the text in the "Location:" box at the top of the window,
type in the new address and depress either the "enter" or "return" key on the
keyboard.
Try it now if you wish. (But remember to click on the "Back" button
to return here.)
There are a number of different browsers, each available in different versions to work with specific computers. Mosaic was the first browser that made the Web possible. Netscape is the browser that is now in widest use (and is the one that is being used here).
HTML:
HTML is the abbreviation for "HyperText Markup Language" which
is the standard language by which all Web documents are described. You don't
have to know HTML to access the Web, but it is important if you want to change
or author Web pages. You can see the HTML document related to any page
by selecting "Source..." from the "View" menu. You can read, copy or print
the text from this view but you can not change it.
Try View Source to take a look at the HTML text for this page.
Hypertext:
Hypertext is a method by which a particular word or
set of words in a document can be linked to a another location in
the same document or in any other document.
It is somewhat similar to having footnotes where the footnotes
describe an exact location in any document.
The true power of the Web is that hypertext links (called "hotlinks")
are performed automatically by computer and the linked documents can exist
on different computers anywhere in the world.
URL:
URL is the abbreviation for "Uniform Resource Locator" which is the
standard addressing scheme by which all Web files or resources are
identified. Each Web page, graphic and resource has its own
unique URL indicated by a "http" prefix. Other standard prefixes refer to other
internet protocols including:
The URL of the current document is shown in the "Location" line at the top of this window. When you position the cursor over any hotlink the URL of the destination will be shown on the line at the bottom of the screen.
As an example, the full URL for the WPL Home Page is
http//:www.ultranet.com/~woblib/index.htm
This or any other page can be printed by selecting "Print..." from the "File" menu at the top left of the screen. If the material printed is too wide to fit on a single sheet of paper you may be able to use "Page Setup..." from the "File" menu to print at a smaller size (e.g. Reduce/Enlarge = 75%).
You can also use the Web to access the MLN catalog from anywhere (via telnet).
To see how this works just click on the MLN hotlink below. When you
are connected use the following steps:
If you have finished this tutorial please send email to the Library now and let us know. Type in your message and include your name When you are finished just click on the "send" button. If you decide not to send the message you can cancel by clicking on the small box in the upper left hand corner of the message window. When you click on either send or cancel the message window will close automatically and you will be returned to this window.
You can also send email at any time by selecting "Mail Document..." from the "File" menu at the top of the screen. The URL and title of the page you are viewing will be included automatically but you will have to type in the exact internet email address.
The University of Michigan has an extensive list of tutorials covering the use of computers and internet for library purposes. These tutorials cover a wide range of subjects and experience levels.
