Zoeken op onderwerp

To search for publications on a certain subject, you must use subject-related indexes, like All words, Title words, Subject and Subject class. After a search via one or more of these indexes, the result may be restricted by non-subject features as Year of publication, Type of publication, Language and finally Location (i.e. a restriction by TU/e Library section). This overview explains how to use all these indexes.

Index	Outline
All words	Index compiled from all author surnames, words from titles, words from annotations, words from corporate names and all subjects, except for stopwords. This index is therefore a mix of subject-related and not subject-related search keys. If you use this index for a search by subject, carefully evaluate the results. Single out the relevant references and determine whether the search term you entered is a subject or not. If it is, a further search may not be necessary; you already searched by a subject. If it is not, you must continue your search. View the relevant references and note especially which subjects have been assigned to them. You may continue your search by using an adequate subject presented in one of the references. You can do this by simply giving that subject a mouse-click. Or use the Similar publications click-through option.
Title words	Index compiled from all single words from titles, except for stopwords. When performing a subject search via title words, languages in which works are written and titles and title words as chosen by authors are important factors. You must therefore enter your search terms in various languages, keep in mind singular and plural forms and spelling variants, and check for synonyms. View the relevant references and note especially which subjects have been assigned to them. Select an adequate subject presented in one of the references, and continue your search by giving that subject a mouse-click. Or use the Similar publications click-through option.
Subject	Index compiled from all subjects assigned to publications in the catalogue. All publications in the catalogue, in whichever language, are assigned subjects from the controlled subjects lists. Searching by subject using subjects is therefore language-independent. Also, checking for synonyms as must be done when using 'Title words' (see above) is unnecessary. When you are performing a search by subjects, carefully view the results, especially those references you consider relevant. Perhaps you will find additional subjects which could improve your search results. You may also use the Similar publications click-through option.
Subject classification	Index of all subject classification. Besides subjects, subject classes are used for indexing and also for shelf arrangement of publications. These subject classes, which serve as a broad index by subject, are designated by three-letter codes. In a subject search, the subject class may be used in three different ways: (1) Use a subject class to make a broad selection, after which you apply restrictions by using other subject-related indexes. (2) Use this index to make sure that search terms have the correct meaning. For example: you search by title word 'Bridge' and then use the subject class index to specify that results should fall within the field of 'Civil engineering'. (3) Use a subject class to make a broad selection, after which you apply restrictions by using non-subject search keys, such as 'Year of publication', 'Type (of publication)', 'Language' and/or 'Location'.
