The purpose of Electronic Course Reserves is to make reserve
materials available 24 hours, 7 days a week anywhere in the world and also
to expand the kinds of materials instructors can currently place on reserve.
Users may view and print or save for later use course materials which
instructors wish to make available to students. The current system includes
sample exams, lecture notes, journal articles, book chapters, images, course
syllabi, and assignments. No copies of entire books are available in electronic
reserve. These may still be checked out at the reserve desk.
We hope that students will find this a time saver and a more complete
resource than the traditional reserve desk. Also, feel free to give us
feedback.

How do I find material my professor has
put on electronic reserve?
Electronic Course Reserves will be available to students officially
enrolled in a class that is participating in this pilot project. Your professor
has been given a userid and password for each course that will have items
on electronic reserve. Your professor is the only person who can give you
this information. Once you have a userid and password be aware that these
are "case sensitive" so you must enter them exactly as they are given to
you. You may access e-Reserves through the Blackboard
Logon page. If you need any other assistance, please call Firestone
Library Reserves Desk at (609) 258-3224 or write to ereserves@princeton.edu.
-
Why do I need a userid and password?
All items are restricted to protect the copyright holder and
require the use of a userid and password to access them. The materials
are to be used for course purpose only and the person using these materials
assumes liability for any infringements of copyright law.
-
What kind of hardware/software will I
need to view the electronic reserve material?
To view Electronic Course Reserve documents, you will need:
-
A Windows PC or a Macintosh
-
Netscape or other World Wide Web client. Netscape is available (for students,
faculty, and staff) through Princeton's Office
of Information Technology.
-
A copy of the DjVu
Browser Plug-in for Windows or Macintosh. This plug-in is already installed
on computers at the public computing sites maintained by OIT and/or the
public workstations within the Library system.
-
A copy of Adobe
Acrobat Reader for Windows or Macintosh. This plug-in is already installed
on computers at the public computing sites maintained by OIT and/or the
public workstations within the Library system.
The majority of the files in the Electronic Course Reserve System are Acrobat
PDF and LizardTech DjVu files, which may be viewed using either Adobe Acrobat
Reader or the DjVu Browser Plug-in. Acrobat and DjVu allow the handling
of a variety of types of materials including those containing graphs, charts,
and mathematical symbols as well as print and images. Both programs retain
the original format of the document and prevents users from modifying or
reusing parts of a document. The Acrobat and DjVu Readers are distributed
free of charge.
If you are working on a computer which does not have the Acrobat Reader
and/or DjVu installed and want to access these readings from your home,
you will need to install the Acrobat Reader and/or DjVu on your computer.
The software can be downloaded from the web at no charge. You will then
need to install the Acrobat
Reader as a plug-in on your own web browser, as well as the DjVu
Browser Plug-in.

How do I retrieve files in Electronic
Course Reserves?
At the Electronic Course Reserve Authenication page, enter the userid
and password your professor has given you. A copyright notice will appear,
you must accept the responsiblities stated before the course listing will
be displayed. A list of the items that are available electronically for
that particular course will display. Click on a title to retrieve the file.
You can also access ereserves through your course Blackboard
site.
Understanding Copyright Fair Use Principles:
Many of your course readings, such as journal articles, may be copyrighted
materials. These materials are identified with a copyright notice. As a
reader of these documents, you are encouraged to comply with fair use.
Fair Use guidelines suggest the following:
-
You may make one copy (e.g., copy to disk or print) for your own personal
reading, research, or education. Any other use without permission from
the copyright holder is illegal. Making multiple copies for republication
or distribution to others would be in violation of Fair Use principles
and practice.
-
Any copy that is made should preserve the author's name, the title of the
document, and a statement of copyright, if there is one.
-
You must not use any of these documents to mislead others about the views
or competence of the author, nor as part of a commercial product.
Other readings may be linked to full text journals available online from
sources such as JSTOR
and Project
Muse or linked to other Internet sites.

How do I view files in Electronic Course
Reserves?
NOTE: If you need help with DjVu, open a course
document, right click anywhere in the viewing window and select Help.
Zoom
The zoom factor (magnification) can be any number from 5% to 999% and refers
to the magnification of the physical dimensions of the image. The plug-in
tries to compute the actual scaling coefficients taking into account the
display and image DPI (Dots Per Inch) information. For example, if you
display a page at 100% then it should appear approximately the same size
on the screen as it was on paper, provided that:
-
You have supplied correct DPI information to the DjVu encoder
-
The physical display resolution is correct. Typically, the display resolution
is assumed to be 100 DPI.
Besides numerical zoom, four more zoom types are recognized:
Zoom
|
Description
|
Fit Width |
Scales the image to fit the
width of the window.
Note: The default behavior is to select one of the fast
zoom factors. As a result, the page will not fit the window's width precisely.
Deselect "Favor fast magnifications for "Fit" resolutions" in the
Preferences to disable this behavior. |
Fit Page |
Scales the image to fit the
window.
Note: The default behavior is to select one of the fast zoom
factors. As a result, the page will not fit the window precisely. Deselect
"Favor fast magnifications for "Fit" resolutions" in the Preferences
to disable this behavior. |
One-to-One |
The image is scaled to display
in pixel-to-pixel mode. In this mode, every pixel of the original image
corresponds to one pixel on the screen. This is different from 100%
zoom where the image is scaled so that its physical dimensions on
the screen are about the same as the dimensions of the original. |
Stretch |
The image is stretched to fit
the window precisely. The original proportions (aspect ratio) are ignored. |
In order to change the zoom factor, you can select the Zoom item
from the pop-up menu. If the toolbar at the bottom of the window is enabled,
you can select the Zoom directly there. Type the zoom factor you
want and hit Enter. This is the fastest known way to set any custom
zoom from 5% to 999%. You can select One-to-One, Fit Width,
Fit Page or Stretch zoom by clicking on the arrow on the
right side of the toolbar.
There are also keyboard shortcuts available that directly set the zoom
factor.
Navigation
If you view a multipage DjVu document you will need a way to navigate through
it page by page. There are three ways to navigate DjVu document:
Navigation using keyboard shortcuts
Keyboard shortcuts are the most useful way to look through a document page
by page. The following hot keys are enabled:
Key
|
Action
|
Page Down, Page Up |
Brings you to the end or beginning
of the current page. If you are already at the beginning or end of the
current page, these keys will move to the next or previous page. |
Space |
Brings you to the next page.
Unlike the Page Down key, it will not go to the bottom of the current
page first. It will move to the next page immediately. |
Backspace |
Move to the previous page. |
Home |
Move to the beginning of the
document. |
End |
Move to the end of the document. |
The above table only contains the keyboard shortcuts for navigation.
Navigation using the popup toolbar
You can also navigate through a multipage DjVu document using the Pop-up
Toolbar.
There are six buttons from the toolbar allowing you to navigate the
previous page, next page, plus/minus 10 pages,
the beginning and end of the document. In addition, you can
select the page you want to see from the tool bar directly. These multipage
navigation items will not be visible on the toolbar if the plug-in is displaying
a single page document.
Please see the Pop-up Toolbar section in the Deja Vu help for
more details.
Navigation using the popup menu
Using the pop-up menu, you can choose an item to Navigate. The following
choices are available: Next Page, Previous Page, +10 Pages,
-10 Pages, First Page, Last Page and Goto Page.
When you select Goto Page, you will get a Goto Page dialog
box where allowing you to specify what page you want to view.
Many of the documents have been set up to automatically enlarge to fit
your screen. On these documents you will find a hand with an arrow on the
palm. Click anywhere on the page, it will automatically fill the screen.
Continue to click on the icon to move through the document. You will not
need to use the scroll bar or forward buttons.
Or you can Click on the magnifying glass button with the plus sign (+)
that appears at the top of the screen. Then move your mouse back onto the
document and click to enlarge the text. Move the scroll bar at the side
and bottom of the page to view other parts of the page.
To move to the next page, click on the right arrow above the document
or move the scroll bar down the screen until the next page appears.
Since we typically scan from photocopies, if the quality of the photocopy
is poor (missing text, added marks, etc.), then the quality of the electronic
version is too. Of course, this is also true for students if they make
photocopies from badly produced printed material on traditional reserve.
Also try clicking on HELP above the document. It gives information on
the other Acrobat Reader tools.

How can I copy/print electronic reserve
materials?
Saving
The options available for saving a document are:
-
Saving the whole document
-
Saving a single page
The Save icon on the popup toolbar saves the whole document.
Saving the whole document
This option is used to save your document into a single file or multiple
files on your system.
This capability is useful if you already have several DjVu documents
in one of the obsolete formats.Since the plug-in understands any of the
four formats (two obsolete and two current) and can save documents in any
of the current formats, it is a convenient tool to do the conversion.
In order to save a multipage document, choose the menu item Save
Document As from the popup menu. The document format selection dialog
will appear. Choose the INDIRECT format if you want every page to
be saved to a separate file (ideal for Web browsing). Choose the BUNDLED
format if you want everything to go into a single file (a good format for
archiving or sending via e-mail).
In the next window, enter the document filename. For BUNDLED
documents, this will be the name of the bundle file. For INDIRECT
documents, this will be the name of the top-level file containing pointers
to page files. The page files will be created in the same directory as
the top-level file. Their names are built-in the document.
Saving a single page
Besides saving the whole document, you can also extract and save just one
(current) page. To do this, choose the menu item Save Page As from
the popup menu.
Printing
When you select the Print option from the DjVu pop-up menu, a Print dialog
box is displayed with the following options:
Printer options
These options enable the selection of a printer from a list of known printers.
Printing to a file is also possible by selecting the Print to file
check box in the Print dialog box. A Properties submenu allows further
specification of the paper size, print orientation, page layout, printing
resolution, image scaling, mirror image, negative printing, and double-sided
printing.
Print range options
All Pages - Prints all pages of a single or a multi-page DjVu document.
Pages - Enables printing of a specified range of pages from a
multi-page document.
Selection - If this check box is selected, the DjVu plug-in prints
only the region of the DjVu page that is being displayed in the plug-in
window. This option enables you to print a selected region of the page.
This is useful for printing large images.
Regular - If this radio button is checked, the plug-in prints
at document resolution.
Reduce to Fit - This radio button enables the DjVu plug-In to
set the optimum resolution so that the image fits completely onto the printed
page.
Current Zoom - If this radio button is checked, the plug-in prints
the DjVu image at the current zoom factor, which is set to view the image
on screen.
Copies
Sets the number of copies of each page printed. The default number of copies
to print for each page is one.
The effects of the Display Mode setting on printing
Black & White - Prints the foreground layer in black and white,
sending the information to the printer using the highest resolution available
in memory. This ensures maximum readability.
Color - The resolution and the quality of color printing is controlled
by the various settings in the Preferences dialog box.
NOTE: The DjVu plug-In does NOT use the Print command that is
found on the main browser menu bar to print DjVu images. Instead, to print
a loaded DjVu image, select the Print option from the DjVu popup Menu,
or click on the print icon on the DjVu popup toolbar.
Copying: Consider downloading the file to a disk for
later use.
On your course selection page, highlight the file name (should appear
as colored hypertext). Click your right mouse button; a drop-down menu
should appear.
Drag your mouse pointer down to "Save link as..."
and click.
A dialog box will appear asking you to specify a file name, file type
and location. Specify the location and name ([A:]3 1/2 Floppy or your [C:]C
drive); name the file; then in the "Save as type" box leave as All files
(*.*) or change the option to "Source". And Save.
Printing: Because many of the documents have been formatted to
fit your screen (icon of hand with an arrow on the palm), printing from
this size is difficult. You have two options, under File, Print, there
is an option "Shrink to Fit", click this box and print one page to be sure
text is readable. OR
Return to the original size to print by using the magnifying glass
button with the minus sign (-). Print one or two pages to test the printing
function. And follow the guidelines below.
Factors to consider which will effect the downloading and printing time:
The size of the file.
The type of network connection with which you are
working
-
A direct ethernet connection will deliver material
much more quickly than will a dialup connection.
The speed of the computer on which you
are working.
-
A computer which will comfortably run Netscape should
be sufficient for downloading Electronic Course Reserve DjVu files.
The type and memory of the printer you
are using.
-
DeskJets and DeskWriters are extremely slow to print
scanned files. Try to use a laser printer for these files.
Before you print:
-
You might choose to print only desired pages rather
than a complete document.
-
Who do I contact with questions?
If you have questions about the readings, contact
the professor or instructor for the course.
If you have problems accessing the page, viewing or printing, contact ereserves@princeton.edu.
