Before you can access Library resources from off campus make sure you have configured your computer with proxy server settings.
After you make a one-time change in your web browser settings, the proxy server will ask you to log in with a CalNet ID or Library PIN when you click on the link to a licensed resource.
Now that you know the types of articles you need, you can choose a database, also known as a periodical index, to find them. Databases are collections of thousands of articles organized by subject. The Libraries have hundreds of databases covering every academic discipline. Some are multi-disciplinary, covering a broad range of subjects and including popular and scholarly sources, and others are subject-specific, and include scholarly and specialized articles. A complete list is available at Find Articles.
The following multi-disciplinary databases are good places to start your research:
Many article databases contain information about articles (citations or abstracts), not the entire text of the article. Once you've used an article database to find articles on your topic, you may need to use this button:
in order to locate and read the full text of the article. The UC-eLinks button appears in nearly all the databases available from the UCB Library website.
UC-eLinks will link you to the online full text of an article if UCB has paid for online access; otherwise, UC-eLinks will help you locate a print copy on the shelf in the library. If UCB doesn't own the article in print or online format, UC-eLinks can also help you order a copy from another library.

You can also set up UC-eLinks to work with Google Scholar. For more information, watch this video tutorial (about 2 min.)
Use OskiCat to locate materials related to your topic, including books, government publications, and audio and video recordings, in the libraries of UC Berkeley. OskiCat will show you the location and availability of the items that we own.
Use Melvyl to locate materials related to your topic located at other campuses in the UC system, or worldwide. You can use the Request button to request an item from another library, if we don't own it.
Melvyl has changed as of January 2012, and now includes many more articles. Detailed Melvyl help.
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:
TK
7881.6
M29
1993
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:
| Q 76 K26 |
QA 17 F75 |
QA 17.1 C98 |
TK 3 Z37 |
TK 29 M49 |
TK 29 M5 1997 |
TK 29 M5 2007 |
Google Books contains millions of scanned books, from libraries and publishers worldwide. You can search the entire text of the books, view previews or "snippets" from books that are still in copyright, and read the full text of out-of-copyright (pre-1923) books. Want to read the entire text of an in-copyright book? Use Google Books' Find in a Library link to locate the book in a UC Berkeley library, or search OskiCat to see if UC Berkeley owns the book.
Why use Google Books?
Library catalogs (like OskiCat) don't search inside books; using a library catalog, you can search only information about the book (title, author, Library of Congress subject headings, etc.). Google Books will let you search inside books, which can be very useful for hard-to-find information. Try it now:
Citation management tools help you manage your research, collect and cite sources, and create bibliographies in a variety of citation styles. Each one has its strengths and weaknesses, but any are easier than doing it by hand!
It's always good to double check the formatting -- sometimes the software doesn't get it quite right.
Plagiarism is a form of academic dishonesty, violating the Berkeley Campus Code of Student Conduct. The campus issues a guide to understanding plagiarism, which states:
"Plagiarism means using another's work without giving credit. You must put others' words in quotation marks and cite your source(s). Citation must also be given when using others' ideas, even when those ideas are paraphrased into your own words."
Plagiarism is a serious violation of academic and student conduct rules and is punishable with a failing grade and possibly more severe action.
In order to avoid plagiarism, you must give credit when

Some reference questions can't be easily answered over e-mail and I am happy to talk with you in person or over the phone if your question is more complex or if you'd like a more in-depth consultation. Trying to schedule appointments via email is time-consuming. Here are some alternatives:
1. Call me at 510-768-7059
2. Use bCal to find my calendar (dorner@berkeley.edu) and locate a free slot between 9-5, Mon-Fri. You can propose an appointment in bCal or contact me by email asking me to reserve that slot for you.
3. If you don't use bCal yet and you have a gmail address, you can send that to me and I'll grant you access to my calendar.
Research Advisory Service for Cal Undergraduates
Book a 30-minute appointment with a librarian who will help refine and focus research inquiries, identify useful online and print sources, and develop search strategies for humanities and social sciences topics (examples of research topics).
This service is for Cal undergraduates only. Graduate students and faculty should contact the library liaison to their department or program for specialized reference consultations.
