Βooks & Maps search
The fields "Author/Cartographer", "Title", "Engraver" and 'Subject' are all indexed. If you click on the link "Thesaurus" below the field and then the relevant letter of the alphabet that may take you quickly to your chosen search term.
The "Year" field is intended as a general, rather than specific search; the results includes items from up to twenty-five years before and after your chosen date; so, if you enter "1570", you will see maps published between 1545 to 1595. This is intended as an aid to identifying anonymous maps, where the user cannot use the "Author/Cartographer" field.
Where ever possible you are advised to use the inbuilt navigation buttons, rather than those of your browser, to avoid unexpected results.
