Frequently Asked Questions
After logging into the proxy server via CalNet, why do I sometimes see a window with a "Connect to Resource" button?
Usually after you have logged in, your browser is redirected straight to the resource you initially requested. However, under two different circumstances, the proxy server instead displays a window containing a "Connect to Resource" button:
- A few resources, such as the Biblioline databases, spawn a new browser window when they are invoked. This can cause problems, which we avoid by instead displaying the window with the "Connect to Resource" button.
- When authentication takes place while you're in the midst of a search operation, you may be returned to a "Connect to Resource" form if the resource sends its search parameters using the "POST" method of data transmission.
In either case, clicking on the "Connect to Resource" button will usually get you where you're going.
Why do I have trouble using my browser's "Back" button beyond the CalNet login screen for the proxy server?
Logging in with a CalNet ID and passphrase triggers a series of exchanges among two campus servers and your browser. Unfortunately, if you try to use your browser's "Back" button to go back to a page you visited before logging in, this may cause you to see a message such as this:
- Missing Data
This document resulted from a POST operation and has expired from the cache. If you wish you can repost the form data to recreate the document by pressing the reload button.
Clicking on the "Back" button repeatedly may or may not get you beyond this roadblock, depending on your browser and what pages it has visited. Whatever you do, do not click on the "Reload" button.
If you want to move back to a page you viewed before logging in, a better solution is to use the tool provided in your browser for displaying a pop-up menu of pages you have visited. This can usually be done by clicking on the "Back" button and holding the mouse button down, or clicking on a small down-arrow or "Go" pulldown next to the "Back" button. The browser's "History" function may also be useful.
The proxy server allows us to provide off-campus access to article databases and other licensed electronic resources to authorized UC Berkeley users, while ensuring we don't provide them to unauthorized users, as required by the terms of our license agreements.
To do this, the proxy server acts as an intermediary between your computer and the Library's licensed electronic resources by virtually providing your machine with a UC Berkeley IP address, as if you were on campus. It is active only when you are accessing these resources.
Anyone may access the library catalogs and most of the Library's web pages from any Internet-connected computer.
Some licensed electronic resources, such as e-books, journal article databases, and online reference tools, are commercial products with access restrictions. UC Berkeley students, faculty and staff members, and some other individuals affiliated with the University, can connect to these resources from off campus using the Library proxy service or VPN.
For more information and setup instructions, see connect from Off Campus.
Browsers configured to use the proxy server must have third party cookies enabled to ensure that images and stylesheets called by the licensed resource are available via the proxy server. Loss of page formatting is an excellent clue that you do not have third party cookies enabled in your browser.

Electronic books come in a variety of forms. Some are accessed through our catalogs and databases and read over the Internet on a computer screen. Others can be downloaded to a computer and in some cases to mobile devices.
As the technologies of eBooks are evolving, so are the formats for citing them in footnotes and bibliographies. Here are guides to citing eBooks in the three most common styles:
- APA (American Psychological Association) - see the section on "Electronic Books"
- MLA (Modern Language Association) - see the section on "Basic Style for Citations of Electronic Sources"
- Chicago - see the section on "Electronic Books and Books Consulted Online"
For more information, see:
- E-Books' Varied Formats Make Citations a Mess for Scholars (Chronicle of Higher Education)
- Find books and eBooks
- Cite sources

In April 2011, the New York Times implemented a "paywall" on its website, nytimes.com. Under this policy [full details here], users can view a maximum of 20 articles per month without charge, but need to purchase a "digital subscription" to go beyond that limit.
Discounted individual subscription rates are available to students, faculty, and staff with email addresses ending in ".edu".
Beyond that, UC Berkeley is not able to provide special campuswide access to the nytimes.com website. However, we do subscribe to several databases that include full text articles from the New York Times along with many other newspapers. For links to these, see our News Databases.
These are available to anyone using our public computers. UC Berkeley students, faculty and staff members can also connect from off campus.
Books and journals are arranged on our shelves according to the Library of Congress (LC) classification system. Each is assigned a unique call number based on its subject matter and other characteristics. Items on the same subject will often be grouped together.
Each call number consists of several elements. For example, consider:
- The FIRST line, TK, is based on the broad subject of the book. Within Class T for technology, TK represents electrical engineering.
- The SECOND line, 7881.6, defines the subject matter more finely. When looking for the book, read this as a whole number with a decimal component. In this example, TK7881.6 represents magnetic recording (a subdivision of TK— electrical engineering).
- The THIRD line, M29, usually indicates author, but may also represent a further subject subdivision, geographic area, etc. There may also be a fourth line, formatted the same way. When looking for the book, read the numeric component as if it were preceded by a decimal point. In the example above, the numeric part of M29 should be read as ".29" (and the call number TK7881.6 M29 comes before TK7881.6 M4).
- The YEAR of publication, such as 1993, may also be present. These file in chronological order and often indicate successive editions of a book. The call number may also have additional elements, such as volume numbers.
In using a call number to locate a book on the shelf, consider each element in turn before moving on to the next segment.
These call numbers are arranged as they should appear on the shelves. In each case, the element shown in boldface distinguishes the number from the preceding one:
