Persistent
Links to Online Articles, Books, and Book Pages in Library Databases.
"Persistent links" (also called "permanent urls" or
"durable urls") provide a method for linking directly to specific articles and
books in the library's online databases. You can use these urls in course
materials such as reading lists and assignments. These are the urls that students
would use in bibliographies in their projects/papers when direct urls are
required.
General
Instructions
Important
Procedures.
- Use the
"permanent" URL to link to items found in Library databases. In most
databases, the url showing in the browser address bar at the
top of the screen is NOT a permanent url. The permanent url
for an article or book will usually be found elsewhere
within the database window. For
database-specific instructions on where to
find the permanent URL, continue reading below.
-
To make the
article accessible from off-campus, you may need to
add a special URL in front of the permanent URL. This will
allow off-campus DSU students/faculty/staff to login with a Library ID and password
to get to the item. Without this change, people
connecting from off-campus will get an error screen or a
login screen from the database itself (and students do not
have logins/passwords that will work on those screens).
The database-specific
instructions below will provide the special url and show
where to place it.
- Test
the links from both
on-campus and off-campus to make sure they are working.
-
Test URLs again at the beginning of new semesters.
-
Links are
usually persistent, but NOT necessarily permanent. So
keep a complete citation for each article that you use; that
way you'll be able to locate the article again if the URL
stops working. When using a link, include the complete
citation. With a complete citation, others will be able to
find the item themselves in the database
--even if the "permanent" link fails.
For information services
that do not allow persistent links, the database name should be included in the
citation so that the article may be found.
ACM Digital Library
The persistent link
for an item in ACM Digital Library
is called
a
"DOI (Digital Object Identifer) Bookmark."
-
On the search results
screen in ACM
Digital Library, click on
the title of an article to
display the article
citation and description.
-
The article's persistent link
can be found on the
line labeled "DOI Bookmark."
-
To
create a link that will work off-campus, place the the
library's proxy url
http://www.ezproxy.dsu.edu:2048/login?url=
directly in
front of the DOI Bookmark URL
-
For
example, in the item below, the DOI Bookmark or persistent link
is: http://doi.acm.org/10.1145/941350.941373
-
To create
the persistent url for use in your course materials, add the proxy url
to the front and create the following URL to use:
http://www.ezproxy.dsu.edu:2048/login?url=http://doi.acm.org/10.1145/941350.941373
The
figure below shows the
location of this article's DOI Bookmark link.
The permanent urls
in ebrary are more difficult to find than in most databases.
-
First, login
to ebrary by clicking on "sign in" in the upper
right corner of the screen. You will login using your
Library ID (begins 21578 and is on the front of your DSU ID
card) as the username. The password is your last name.
-
When you have found a book in search
results, click on the title to open it to the Table of
Contents.
-
On
the right side of the screen, just above the Table of
Contents, click on "Add to My Bookshelf." This will place
the book on your "bookshelf."
-
At
the top of the ebrary window, click on the tab labeled
"Bookshelf" to display bookshelf items. Here is a bookshelf
with one item:
-
Find the book you want; right-click on
its title; and select "copy link location." Then paste that
location as the hyperlink (url) in your document, webpage or
course management system.
-
If you highlight
text in a book, each of those highlighted sections will also
show on the Bookshelf. For a persistent link to that
specific part of the book, right-click on "highlight" link
and select "copy link location" to then paste the url where
you need it.
-
Here is an example of an ebrary
persistent link to a book:
http://site.ebrary.com/lib/dakotastate/docDetail.action?docID=10235272
for databases Academic Search Premier, Business Search Premier,
and other databases provided by EBSCOhost
The
persistent link for an item is an EBSCOhost database is referred to as
the “Persistent link to this record
(Permalink).”
The figure
below shows the
location of a persistent link.

IEEE CS
Digital Library Instructions
The persistent link
for an item in
IEEE CS Digital Library
is called
a "DOI (Digital Object Identifer) Bookmark."
-
On the search results
screen, click on
the Abstract icon of an article to
display the article
citation and description.
-
The article's persistent link
can be found on the
line labeled "DOI Bookmark."
-
To
create a link that will work off-campus, place the the
library's proxy url
http://www.ezproxy.dsu.edu:2048/login?url=
directly in
front of the DOI Bookmark URL
-
For
example, in the item below, the DOI Bookmark or persistent link
is: http://doi.ieeecomputersociety.org/10.1109/SERVICES-1.2008.72
-
To create
the url for use in your course materials, add the proxy url
to the front and create the following URL to use:
http://www.ezproxy.dsu.edu:2048/login?url=http://doi.ieeecomputersociety.org/10.1109/SERVICES-1.2008.72
This figure shows the
location of this article's DOI bookmark link.
for
databases ABI-INFORM Complete, Proquest Research Library,
Proquest Education Periodicals, and other databases provided by
Proquest
The persistent link
for an item in Proquest is referred to
as "Document URL."
-
On
the search results screen, click
on the title of an article to
display the article citation and
description.
-
The article's
persistent link
can be found on the line labeled

for a book or a page in a book may be found at the bottom of
each screen and is labeled only "url"
-
To
create a link that will work off-campus, place the the
library's proxy url
http://www.ezproxy.dsu.edu:2048/login?url=
directly in
front of the DOI Bookmark URL
-
For
example,
if the persistent link
is:
URL
http://proquest.safaribooksonline.com/9780136083238
-
To create
the url for use in your course materials, add the proxy url
to the front and create the following URL to use. Be careful
