Over 15,000 source materials indexed Full text linking to 6,700 journals, From 280 Publishers Indexes the worlds chemical literature All languages All patents This year to date, CAS' weekly input has reached an average of 20,924 records, compared to 19,551 per week in the record analysis year 2006, an increase of 7%. 5 Coverage CAS claims Over 15,000 source materials indexed Full text linking to 6,700 journals, From 280 Publishers Indexes the worlds chemical literature All languages All patents This year to date, CAS' weekly input has reached an average of 20,924 records, compared to 19,551 per week in the record analysis year 2006, an increase of 7%. 6 Competition ScifinderBeilstein & Gmellin Current Contents Engineering Village Web Of Science StrengthMolecular structure + text searches Information checked Most complete molecule search tools CompletenessBest for conference proceedings Great search tools Cited Reference Search CoverageChem literature All literatureEngineering literature All Literature CompletenessClaims all since 1980, some before Most since 1771 All since 1993Many since 1800 Most since 1980 Conference proceedings ACS onlyNo ManyNo Structure search Good No Logical search (and or not) minimalSomegoodbestYes Cited ref search Newer references No noyes 7 Key Limitations Of Scifinder Librarians/linguists not chemists do most indexing Indexing by CAS number not IUPAC structure Misses articles not published in chemical journals e.g. IEEE sensors, MRI imaging Patent coverage spotty Logical searches particularly weak You can and two searches on your computer, but only after you download them 100 references at a time Weird license limitations 8 License Limitations For Scifinder Download at most 100 references at a time, 5000 per session Requires downloads to do logical (And/or) searching Allowed to only keep 5000 search results at a time in format written by scifinder No limitation on references imported to endnote or refworks provided search results deleted from your computer No commercial/consulting use 9 Basic Use of Scifinder 10 Search Results Depend On How Search Is Done 499 References 609 references 11 Search Results More information about paper Includes key words and references Full text of Article Cited reference search 12 Structure Searches Structure search Start scifinder Go to explore Click chemical structure Draw structure Search 13 The Drawing Screen Simple starting structures Add alkyl chains Add atoms Add ligands Add variable structures 14 Get Substances 15 Substances Found References found Commercial sources and prices Regulatory issues Reactions 16 References Opens the abstract Go to full text 17 Scifinder tutorial pageeseminarlisting.htmleseminarlisting.html 18 Tutorial on Structure Drawing 19 Reaction Drawing Tutorial 20 Cautions With Scifinder Scifinder search engine misses things Search by structure & search by name and by research topic will give different results I usually do all three 21 Summary Scifinder is one of the most powerful tools for searching the chemical literature Best for literature after 1990 Available for download All chemical scientists should know how to use it
