Menus support users in building and saving search strategies, e.g. a database menu by subject. Searchers also have the option of an expert mode. They can prepare scripts offline and upload them complete, line by line, or in any order. The interface can export sessions including images straight into word processing software in RTF format. The new QWEB interface particularly supports fast, high-quality display of images such as logotypes and patents drawing.
Searchers just click to view integrated images, including a link to very high quality TIFF images.
QWEB provides additional security with SSL search encryption. A Remember My Details option lets users store user IDs and passwords for automatic use. According to Lambert, downloading chemical structure images integrated into files has been endurable, but downloading Derwent images takes forever. QWEB works with Netscape Navigator 4.x or above, or Microsoft Internet Explorer 4.x or above, with Java script enabled. A screen resolution of 800x600 pixels or higher is recommended.
