Chemists have long been familiar with search engines that aspire to index a large proportion of the chemical literature. Think for example the old-generation (and commercial)\u00a0SciFinder (Scholar)<\/a>\u00a0and Reaxys<\/a>\u00a0or those that arrived in the 1990s in the online era\u2021<\/sup> such as the non-commercial Pubchem<\/a> or ChemSpider<\/a> (there are more). But you may not be as familiar with the latest generation of global search engines and here I will focus on three relatively new ones that specialise specifically in tracking down data rather than just publications.<\/p>\n

I will illustrate first using a regular<\/i> or non-advanced<\/i> search. The keyword will be obtusallene<\/strong>, which is selected largely because it is a relatively unique string which is likely to result in fewer false positives. It is a family of marine alkaloids containing, unusually, bromine and \/or chlorine[1]<\/a><\/span> and the citation here is to a journal article describing some of its chemistry. But what if you want to find data associated with such molecules?<\/p>\n

  1. DataCite<\/strong> (the name gives a clue) specialises in finding data. It was launched ten years ago and has been rapidly expanding its index since. A regular search can be formulated using the string\n
