UCB students, faculty and staff now have access to the web version of the Inorganic Crystal Structure Database. Access is by IP address so you should not be prompted for a password or login. Once you are at the site, click the link in the second paragraph titled “Login or use the Demo”. Once you enter a query, you actually are searching the Full database, if the system is working properly. Be sure to look at the bottom of your results page after you have entered a query, the "Demo database" text should have disappeared and only the notation, “Full database will be used if available after the first query is entered” remains.
Some people have reported difficulties in accessing the database so please note the instructions on the introductory page, especially this section: ICSD-for-WWW works with Win95 up to Mac-OSX & Linux, but not with old browsers. Do not disable popups, cookies or javascript. In the browser options, prefer to open new pages in a new window, not a new tab. If you have problems, use a modern browser like Mozilla Firefox. With Internet Explorer, please include ICSD as a "trusted site" under "security".
Also note the ICSD Conditions of Use, "Information retrieved from the database shall not be passed on to third parties not belonging to the group of authorised users."
