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

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
