ClassWeb is an integrated cataloging tool that assists with the assignment of Library of Congress classification numbers for bibliographic content. ClassWeb is accessed over the Internet using a standard Web browser and is kept up-to-date with the latest LC classification and authority data. In addition to extensive cross referencing thoughout the system, there are links to external library OPACs. You can configure your ClassWeb account to select from a list of pre-defined OPACs as well as set up a custom link to an OPAC that is not already in the list.
Most pages in ClassWeb have a help link or button that will take you to the on-line documentation for that area of the system. In addition, most links and buttons in ClassWeb have a short help message that pops up when you hold your mouse over the link or button.

When you click on a page title, you will be taken one level up in the help system.
There are three ways of logging into ClassWeb:
Most of the ClassWeb menus are configured for manual login. If you send a request to the server and you are not already logged in, you will be prompted for a "Login name" and "Password".
Each account may have up to three passwords: a regular password which has administrative privileges (the ability to update your account settings and create local notes), an editor's password (with the ability to edit local notes but not account settings) and a read-only password (which provides read-only access to your account). A new account only has an administrative password. You can add the other two passwords on the account settings page. Because each of the three passwords has to be different, the password you use during login determines whether you have administrative, editing or read-only permissions.
By selecting the Save your user name on this computer check-box, the system will save your login name on your computer using a web browser cookie. This option will cause the login name field to be filled in whenever you log in.
The only way to change the regular (administrative) password is through the login screen. If you check the Change password box when you log in, you will be prompted to change your regular (administrative) password.
If your institution has a fixed set of Internet Protocol (IP) addresses, you can configure your account so that any computer within that range of IP addresses can be logged in automatically for read-only access. For instututions that do not have fixed IP addresses or do not want to allow automatic login for all computers within those IP addresses, you can still enable automatic read-only login on a computer-by-computer basis. See the next two sections for auto-login options.
Auto Login by IP Address
Auto login by IP Address can only be configured for computers that use one or more static (non-changing) IP addresses (for example, a campus that has been assigned a block of IP addresses for its computers). You configure this feature in your account settings (additional documentation).
Once your account is properly configured, use one of the Auto Login menus to access ClassWeb. Your computer will be automatically logged in to your account with read-only access privileges (the same as if you had manually logged in with the read-only password). Users that log in automatically cannot update account preferences or edit local notes. Even if you configure your account to allow auto login, you can still use the regular Manual Login menus to login with a password in order to have administrative priveleges.
Auto Login by Registered Computers
In addition to automatic login by IP address, you can also configure your account so that individual computers can be registered to automatically login for read-only access. This is useful for institutions that don't have static IP addresses or don't want to provide access to all computers in an IP address range, and for situations where computers are being used outside of your usual network (i.e. off site).
First, to enable this feature, use the Settings link found on the drop-down menu at the top of every page, select the Login tab and then select the option that reads: Enable automatic login by registered computers. After you save your change with the Save button in the upper-right corner of the settings page, a unique registration number will be assigne to your account.
Then, for any computer you want to register, use that computer to log into ClassWeb, making sure you have checked the box Register this computer for auto-login on the login screen. This will store your account's unique registration number as a permanent cookie on that computer and will allow that computer to login automatically via the Auto Login Menu.
You can disable this feature at any time by unselecting the same checkbox on the Login tab of the settings screen and then clicking on the Save button. This will prevent any registered computers from logging into your account automatically -- they will need to manually log in. The next time you enable this feature, a new registration number will be created to identify your account. All previously registered computers will need to register again via the login screen to receive the new number.
It is always a good idea to log out of ClassWeb when you are finished for both security reasons and to release your session for someone else at your institution. All sessions automatically time-out (expire) after one hour of inactivity, effectively logging you out. For solo-user accounts that have a monthly time limitation, you are not penalized if you forget to log out -- the length of your session is based on the last request you submit.
Although you might have more than one ClassWeb window open on your computer, once you have logged out from any of them, you will be logged out of the server -- you don't have to log out of each window. Also note that closing a window does not log you out of the server. Neither does exiting your browser or turning off your computer. If you return to ClassWeb within an hour, you will still be logged in unless you clicked on the Sign out link.
Click on the the nagivation menu button on any screen and the last item in the list will always be Sign out.i
Here is an example of the navigation menu in the classification browser:
A number of options can be set for your account using the Settings link found on the Navigation Menu at the top of every page. These settings affect everyone who logs in to your account. Some of these options (like the number of records to return on the search screens) can be overridden but the values on your preferences screen is the starting or default value for that option.
Many of the options that you select on a given ClassWeb page (like the number of records to return at a time and which classification subsets you are using) are passed from screen to screen as you navigate through the system. To reset these values to the defaults for your account, return to any menu and proceed from there. Note that this will only affect the current window or browser tab and that any additional windows or tabs that you have open will continue to use their existing settings.
Because of the way ClassWeb passes information between your web browser and the server, you can bookmark most of the web pages returned to you in order to return to that exact location in the future. ClassWeb also includes a bookmark making tool to assist you in making bookmarks for starting the site in different configurations.
A link to the bookmark tool can be found near the bottom of the main menu. It will launch ClassWeb with the options you select and you can bookmark that page. If you are asked to log in, do that before creating a bookmark.
Web Browser Requirements
ClassWeb supports recent versions of most major web browsers except Microsoft Internet Explorer (MSIE). MSIE is not being actively improved by Microsft and it cannot run the newer web technologies that ClassWeb relies on to improve your end-user experience. Microsoft has replaced MSIE with their Edge browser which is installed as part of Windows 10. This browser does work with ClassWeb.
The following web browsers have been successfully tested with ClassWeb: Apple Safari, Google Chrome, Microsoft Edge, Mozilla Firefox and SeaMonkey.
ClassWeb uses web browser cookies to identify you after you have logged in and to keep track of certain preferences. These cookies are stored on your computer. You are free to remove these cookies if you are not logged into ClassWeb but it is very important that nothing interferes with these cookies during an active session.
ClassWeb supports the full range of characters available in the Unicode display. While vernacular language data will be added to areas of the classification database over time, any records that include diacritics will display in a more visually pleasing manner when using Unicode.
