CD-ROMs

During inspection imaging processing features are used to observe details of the image. After inspection the images are stored on a CD ROM/XA diskette. 

Real Time X-Ray images are stored on CD ROM/XA. Compared to film the volume for a storage is reduced by a factor 50. Retrieving is easy since information of the location is given in the directory of the diskette. Normally the directory name is the shop order and the file name is the serial number of the part. The directory and file names can be customised. 

The data can be retrieved easier, since no pile of films is laying on the table of the inspector. With each CD-ROM diskette a leaflet with relevant information for traceability of data is provided.

Most database users do not know how the data are organized in a database system (DBS) they depend solely on the application programs. This is sufficient for most database searches where users can receive large amounts of results quickly and easily, e.g., on literature or other information. Nevertheless, a basic knowledge on where and how to find deeper or more detailed information is quite useful. Due to their complex nature, comprehensive searches (e.g., for processes or patents) are not recommended for beginners. However, most local (in-house), online, and CD-ROM databases provide extensive tutorials and help functions that are specific to the database, and that give a substantial introduction into database searching.

The pre-processing concepts have been a more recent development of substructure searching systems. These approaches have become popular since the mid-1980s, when the cost of the storage devices (hard disks and CD-ROMs) decreased.

The effort to clarify and articulate the principles of spectrometry as simply as possible appears to have struck a welcome response among those who use mass spectrometers. The original series was not advertised, but, once it had been discovered outside the Micromass organization, there were inquiries as to how it could be purchased. From the start. Micromass offered the series free in a ring-binder format and later also provided it free on CD ROM and then on the Internet. Updating of the first CD led to over 600 requests for it on the day after its release had been announced on the Internet. Partly because of this response — but mainly because users or potential users frequently like to have a traditional reference book — it was decided to publish the series in this present book form. 

Budgeting. These changes in the storage and retrieval of chemical information requite that Hbraries and information centers now consider not only what should be purchased but also what monies should be allocated for the purchase of information in nonprint formats such as CD-ROMs (compact disk read-only memory) and on-line databases. Coupled with this is budgeting for the cost of hardware and software to enable the rapid and cost-effective deHvery of needed information (15). The geometric increase in sources, both printed and on-line, has increased the role of information speciaHst as an expert in the deHvery of chemical information. Retrieval from increasingly diverse and complex sources becomes the paramount issue for searchers of chemical Hterature in the 1990s. 

In 1982, the European Space Agency s Information Retrieval Service (ESA/IRS) introduced the ZOOM command, providing users with a mechanism to analy2e retrieved sets. In 1984, service at a baud rate of 2400 was made available by Tymnet and Telenet for pubHc access to on-line databases. In 1985, the first commercial CD-ROM drives for personal computers became available, along with the first commercial CD-ROM databases. 

Nuclear Magnetic Resonance Spectroscopy. Bmker s database, designed for use with its spectrophotometers, contains 20,000 C-nmr and H-nmr, as weU as a combined nmr-ms database (66). Sadder Laboratories markets a PC-based system that can search its coUection of 30,000 C-nmr spectra by substmcture as weU as by peak assignments and by fiiU spectmm (64). Other databases include one by Varian and a CD-ROM system containing polymer spectra produced by Tsukuba University, Japan. CSEARCH, a system developed at the University of Vieima by Robien, searches a database of almost 16,000 C-nmr. Molecular Design Limited (MDL) has adapted the Robien database to be searched in the MACCS and ISIS graphical display and search environment (63). Projects are under way to link the MDL system with the Sadder Hbrary and its unique search capabiHties. 

The National Chemical Laboratory for Industry (NCLl), Japan, has developed an integrated Spectral Database System (SDBS) which is available to users in Japan. AU spectra were deterrnined at NCLl under controUed conditions and are available on a PC/CD-ROM or magnetic tape. The system has both H-nmr (6000 compounds) and C-nmr spectra (5700 compounds), along with searching software. NCLl has also developed an integrated C— H-nmr system that can be used for two-dimensional data elucidation (70,71). 

Mass Spectroscopy. A coUection of 125,000 spectra is maintained at Cornell University and is avaUable from John WUey Sons, Inc. (New York) on CD-ROM or magnetic tape. The spectra can be evaluated using a quaHty index algorithm (63,76). Software for use with the magnetic tape version to match unknowns is distributed by Cornell (77). The coUection contains aU avaUable spectral information, including isotopicaUy labeled derivatives, partial spectra, and multiple spectra of a single compound.
