Browser Compatibility and Configuration

The library provides access to scores of databases and other electronic resources. Some of these resources have special requirements such as javascript, cookies, support of style sheets, unicode fonts, and so forth. This page will help you configure your browser to meet most such requirements.

For Windows users, the library recommends Firefox, Microsoft Internet Explorer 6+, Opera 6+, or Netscape 7+. For Apple Macintosh users, the library recommends Firefox, Netscape 7+, Opera 6+, or Safari. The bad news is that Microsoft Internet Explorer 5.x on Mac does NOT work well with some library products.

Your present browser configuration

JavaScript

JavaScript is a programming language used by many sites on the web and by many of the electronic resources provided by the library. JavaScript capability is included in every major web browser. But you may need to turn it on in order to use some library resources. Here is how to activate JavaScript in Netscape and Internet Explorer.

How to activate JavaScript in Netscape 7.x

  2. Select Preferences
  3. Double-click on Advanced to expand the list of options

Note on JavaScript privacy/security

Although JavaScript is listed in the privacy/security section of Internet Explorer, turning on JavaScript is not a security risk. Unlike other progammming languages, JavaScript was designed to be "virus-safe." It is extremely difficult for a malicious programmer to use JavaScript to do any real damage to your computer. For example, JavaScript cannot create or remove files on your computer (except cookies). JavaScript programs can theoretically transmit personal information about you IF you provide that information, for example by completing an order form. JavaScript can be used to play annoying tricks like telling a page to reload itself if you try to leave it.

Cookies

Here is how to enable cookies on Netscape and Internet Explorer. If you change your cookie settings, you may need to close and re-open your browser to use the new settings. Note that firewall/security programs on your computer (like Norton or ZoneAlarm ) or on your local network can block cookies even if your browser has cookies turned on. If your browser has cookies enabled but you still get an error message about cookies when you attempt to use library resources, then the problem may be caused by your firewall software or by your company LAN (if you are browsing from work) or possibly even by your ISP (very unlikely).

Note on cookie privacy/security

Cookies are records of information about you. If you have cookies turned on, then you are giving permission for a website to create a cookie on your machine (i.e., store a small amount of information on your computer) or to read a cookie that same website previously saved on your machine. For example, a website might use cookies to store information about you such as your browsing preferences, or your name, address, or telephone number. The next time you visit that website, it will read the cookie and "remember" this information. A website can only read its own cookies. In other words, it only knows the information you give it. A website cannot read cookies created by a different website. It is theoretically possible for a website to store important confidential information in a cookie such as a credit card number or a password. This is not safe unless it is well encrypted.

There are two kinds of cookies: transient and persistent. (Transient cookies are also called session cookies.) A transient cookie is stored in memory and disappears when you exit the browser software or turn off your computer. There is no permanent record of the cookie information. Persistent cookies, on the other hand, are saved as files on your disk and carry an expiration date. Cookies may persist for years. Some library resources use transient cookies, including the proxy server. A very few optionally use peristent cookies if you permit it. Very few library resources require persistent cookies.

If you have privacy concerns about cookies, then you may wish to configure your browser to allow only transient cookies. These transient/temporary cookies are never written to a disk file; they exist only during your browser session. In recent Microsoft products, a security setting of "medium" allows transient cookies but blocks persistent cookies. A setting of "high" blocks all cookies. You may also wish to allow only first-party cookies and disallow second-party or third-party cookies (also called foreign cookies because they are stored not by a site you visit, but by a site that is cooperating with a site you visit—a partner.)

Even if you have configured your browser to allow the creation of persistent cookies, you can still instruct your browser to delete all existing cookies whenever you wish. You can also go to your cookie folder and delete individual cookies just as you would delete any file on your computer.
