Background Beilstein- Handbook of Organic Chemistry (1st Ed. 1881) Gmelin- Handbook of Inorganic & Organometallic Chemistry (1st Ed. 1817) Organic Chemistry and Life Science Patents - (USA-since 1976; World/Europe-since 1978)
Handbook of Organic Chemistry (1st ed. 1881)
BeilsteinHistory 1881 - 1st Ed. Handbook of Organic Chemistry By Friedrich KonradBeilstein (Russian chemist) 1885 - 2nd Edition 1906 - 3rd Ed. and death of Beilstein 1918 - 4th Ed. by German Chemical Society 1984-1998 - Print 5th Supple./4th Ed. (covers 1960-1979) Only v. 17-27 (Heterocycles) published (English). Ceased publication in 1998 1994 - Beilstein Client ‘CrossFire’ introduced! (Handbuch migrated to a database in 1980’s) 2009 - Reaxys - web-based platform introduced!
Beilstein Literature Coverage 1980-1994 - Cut back to 80 prime journals increasing over time to 120 journals (no patents) 1980+ - Abstracts included 1995 - Increased to 180 journals, adding ecotox & pharmacology coverage Currently ~220 journals covered
beilstein Today Today, "Beilstein" represents the Handbook, Beilstein Online, CrossFire, CrossFire plus Reactions, and CrossFireGmelin, Autonom, Current Facts, and more.
Beilstein NEWS 2007 Elsevier acquired Beilstein database from frankfurt-based Beilstein Institute (Full Ownership) 1st major open access chemistry journal – Beilstein J. of Organic Chemistry
BeilsteinSearch Note Only about 50% of the compounds have CAS Registry Numbers Name searching is unreliable since Beilstein has relatively few synonyms Only sure search is a “Structure Search”
1852 5th edition HandbuchderTheoretischenChemie (organic chemistry was seperated and covered by Beilstein)
1922 8th edition (last edition).
Supplements to the books continued to be issued.

Endnote Yes - When you open the Output tool, select "Literature Management Systems" and then import your hits or range of hits into EndNote or other bibliographic management software.
How to search? By structure, sub-structure (note - can generate structure from name!) By numerical values of properties By text, author(s) e.g., Bibliographic information Advanced searching for entering complex property/combination queries following the general rule "<field code> <operator> <field value(s)>"
Alerts Need to register (Free) and then you can create alerts for your searches as well as customize your settings (e.g., colors of structure and text, hits per page, and searching options).
History Sets History sets can be combined using AND, OR, NOT Boolean Operators.
