CA/CAplus enhanced with pre-1907 records from Chemisches Zentralblatt
Nearly 18,000 records from the 1905-1906 issues of Chemisches Zentralblatt have been added to CA/CAplus. A predecessor to Chemical AbstractsTM, Chemisches Zentralblatt is a German chemical abstracting journal published from 1830-1969.
The new pre-1907 records have been enhanced with English machine translations of Bibliographic (BIB) and Abstract (AB) information. In the Title (TI) and AB fields, translated data is indicated by "machine translation" and "Machine Translation of Descriptors", respectively.
CAplus enhanced with traditional medicine patents from 1985-2005
CAplus has been enhanced with approximately 10,000 traditional medicine patents from 1985-2005. These patents are not represented by new or different kind codes and are not assigned to a CA section.
In the IPC.TAB display format, XC may appear in the CC column (authority issuing the International Patent Classification code). XC indicates that the patent has been examined by CAS, but it is not part of the reclassification supplied by the European Patent Office (EPO). The presence of XC provides an additional way to search IPC codes.
