CrossFire Gmelin

CrossFire Beilstein is available to subscribers as part of the CrossFire Database Suite. This package consists of CrossFire Beilstein, CrossFire Gmelin, and Patent Chemistry Database. Since January 2009, the contents of these three databases have been merged and are accessible through a new web-based interface, Reaxys (Table 1.4). 

In many ways, the field of chemistry is extremely fortunate in having had powerful, specialized searching tools like SciFinder Scholar, STN Express, and MDL Crossfire (for Beilstein and Gmelin) available for many years. These tools permit a high degree of flexibility in searching for example, one can find journal articles that refer to compounds containing particular substructures, search for physical properties of particular compounds, and so on. However, these are bounded tools ... 

Many chemists therefore take the view that the Beilstein and Gmelin files may be regarded as factual files, while the CAS and Derwent files are not. In the sense of the approach of the present article, this is certainly unfair to the latter pair, It is certainly true that in particular cases the generalized description of a property described in a generalized way in the abstract of a document may lead to valuable results which would be difficult or impossible to obtain without this form of soft data retrieval. For this very reason, Beilstein s CrossFire system has now started to include more and more soft data in the form of abstracts, titles, and other qualitative free text in its databases. 

Factual databases are generally described in terms of the standardization of the data structure and the data content. In the case of the Beilstein file and CrossFire the following distinction is important to note, and will apply also to other major sources of factual data (e.g., Gmelin). 

Chemical Abstracts, Beilstein, and Gmelin via Crossfire and some other indices are wonderful tools for finding articles.
