How do I find ... ?Theses Newspapers
The advanced search function provides boolean capabilities as well as limiters. It is possible to limit by several material types and search for keywords within the subject, author or title fields. It is also possible to combine searches on different fields.
The most basic search, a simple "AND"ing together of two terms can be performed from the Basic or Advanced search templates. This consists of choosing an index by using the downward pointing arrow to view the options and inputting two or more words into the first box of the template.
This search would find items with both dogs and cats in the title.(see also Keyword Searching). The Advanced Keyword template, however, permits you to use alternate boolean operators (OR and NOT)
Boolean is what we call the logic behind the combination of terms. There are three principal types of boolean operators (AND, OR and NOT). They are represented in the template by the drop-down menus which precede the choice of index. Placing your mouse over the down arrow and clicking will allow you to view theses options.
Boolean logic within the template is prioritized. The following search would be interpreted by resAnet as (gabriel and dumont) or (louis and riel). Each line represents a set. You would retrieve items with either Gabriel and Dumont or Louis and Riel in the title.
It is also possible to use different indexes: The search above would retrieve items with green and gables in the title but not with montgomery as an author.
Phrase searching is performed by using quotation marks.
The search would find items with the phrase Joseph Brant in the title. Similarly, compound words such as mid-wife and phrases such as Eric the Red should be contained within quotation marks.
Truncation in resAnet involves the shortening of a word with the use of a symbol to represent an unlimited number of characters at the end of a word.
Truncation is used when one wishes to find variants of a word. The question mark is used to truncate words.
The search would find items with variant endings of the word e.g. rebellion, rebellions, rebellious, rebelliousness in the title.
It may also represent no character e.g. rebellion? would retrieve items with the word rebellion as well as rebellions.
Wild Cards are symbols which represent a single character in search string. As with truncation they may also represent no character. The # symbol is used to represent a wild card.
The search above would retrieve items with the Canadian spelling of neighbour as well as the American neighbor. The wild card may also be used to search for plurals e.g. wom#n or election#.
Limiters allow you to restrict your search by language, place of publication, time period or type of material.
You must have at least one search term in the search template in order to use limiters. The template will not allow you to search, for example, for all the National Library's holdings in English without an added search parameter (e.g. a keyword from the title).
To limit by Date
After choosing a search term you may wish to limit by date. The default date operator will be "equal to". If you wish to retrieve items published only in a particular year, you would input a year and leave the default = sign as it is. If you wanted items published before 1984 the search would look like this:
- = equal to
- < before
- > after
- <= before or equal to
- >= after or equal to
To limit by Place of Publication:
Select a province or country from the drop-down menu. Not all countries are represented on this list for countries not listed you may wish to chose "Other". The Language limiter allows you to limit to either French or English material. The Material Type limiter allows limiting by several different material types to view the options simply click on the drop down arrow.
How do I find ...?
Theses can be searched through keywords in the title or author fields. In order to limit your search to theses you must use the Advanced Search. Theses are not assigned subject headings so the best way to perform a search on a particular topic is to use title keywords You then must chose "Theses" as a material type.
Newspapers are not easy to locate within a bibliographic database. Please refer to our resource guides for Canadian newspapers.
