While many databases are focused on similar subjects, each database is unique. Differences may
result from types of publications covered, data included, indexing standards, the presence of a
thesaurus, or special formatting options. Details of each database are documented in its Bluesheet.
A Dialog Bluesheet contains a description of the database content, provider contact information,
features specific to the database. Bluesheets are available in PDF format online at library.dialog.
