While your background research in subject encyclopedias has given you good information on your query for the effects of the Holocaust on survivors and subsequent generations, that research bibliography stops in the mid 1980s. All these publication types, usually called periodicals, are reviewed , indexed and abstracted in a number of different databases. If you recall the indexing process we covered in Module II, you understand something of the process of indexing and abstracting.
Different databases have different lists of subject headings or descriptors.
This depends on the subject focus of the database and whether you need scholarly or general information. Additional considerations may be whether the information can be provided in full-text online.
