„ESTONIAN SUBJECT THESAURUS“ (EMS) USING HELP At the top of the subject thesaurus home page you can find a search box for keyword search, the left column allows to browse the list of subject fields. The right column gives the short introduction to EMS. SEARCH You must write the keyword in the search box. You can search by the beginning of the word, part of the word or the exact equivalent, from among Estonian and English language terms or simultaneously both (choose from the drop-down menu). The keyword must consist of at least one letter. Any letter with diacritical marks not appearing in the Estonian alphabet can be searched by the basic letter. In the left column, the search will display a list ofidentified preferred terms and nonpreferred terms. The nonpreferred term or synonym gives reference to the subject term to be used (reference USE). The header of the column displays details of the search (how many records were searched and by which elements). In case of no result (message 0 records), you should extend the search and preferably search by shorter beginning or part of the word. Clicking the term in the list opens the record of the term on the right. The record of the subject term displays the subject term in use, its English-language equivalents, explanation, synonyms (in the field Replaces), relations with other subject terms (in the fields Broader, Narrower, Related) and the subject fields where the subject term belongs. The record ends with a permalink and links for downloading the record in human-readable MARC21 format (Marc21-I), machine-readable MARC21-format (Marc21) and MARCXML-format (MarcXML). The record of the nonpreferred term displays the term that is not used as the subject term, its English-language equivalent, reference to the subject term and the subject fields where the term belongs. To view all the terms in the list as records at one time, you must use the command View records. If the number of records exceeds 25, they can be viewed page by page. The list of records displayed on the right can be converted into a list of terms by using the command View the list. All related subject terms provide a link to the record of the particular term. All records contain links for search with this term in the online catalogue ESTER, article database ISE, digital archive Digar, national bibliography database ERB and internet search in Google. The command Limit by subject field enables to find from the list of search results the terms belonging to one subject field. You have to choose the subject field from the menu and confirm it with the button Limit (piira). The same can be done in the list of records. BROWSING SUBJECT FIELDS The subject terms are divided into numbered subject fields. The same subject term can belong to several subject fields. NB! The numbering has gaps in it, please do not let it confuse you. The list of subject fields with numbers is displayed on the front page in the left column. You can always return to the list of subject fields via the link Subject fields. Subject fields can be sorted by numbers or subject words by clicking respectively No or Subject field in the header. When clicking the name of the subject field, the list of subject terms of this subject field is displayed on the left. NB! The loading and displaying of longer subject field lists may take about twenty seconds! The command See records displays the same subject terms as records in the right column. CHRONOLOGICAL TERMS AND FORM TERMS You can separately browse chronological terms expressed in digits and form terms (the latter contain also genre terms) by clicking the corresponding links in the top panel menu. SAMPLES You can compile a sample of subject term records by selecting the desired records and clicking the button Add to sample. Clicking the link Samples enables to view the sample.

When you click the name of the sample, you can view the subject terms collected under this sample. If you wish to delete subject terms from the sample, you must open the sample, select the corresponding terms and click the button Delete from sample. The sample will be updated and the new result will be displayed. During the current session you can delete terms from the sample compiled by the editors but it will turn into My sample and the sample prepared by the editors will not change.
