Search Guides (Library Website)
I'm looking for a material titled _____. How should I begin?
Please refer to the following pages for details.
Guide Sheet List 2-1
What should I do if I know only the beginning of the title of the material?
Select one of them and click the [Search] button.
How do I search with an ISBN or ISSN (number)?
You can also perform a search from the advanced search screen by clicking the [Advanced Search] button on the Nagoya Univ] tab.
You can perform a search by filling in the ISBN/ISSN field.
ISBN (International Standard Book Number): This number identifies a book.
ISSN (International Standard Serial Number): This number identifies a serial.
What characters can I use with the [Nagoya Univ] tab?
On the Japanese-language pages, you can use Kanji, Hiragana, Katakana, and alphanumeric characters. For alphanumeric characters, you can enter uppercase and lowercase characters. Both single-byte and double-byte characters can be entered.
Searches of Arabic script, Devanagari script, African languages, and Southeast Asian languages
Searches can use the original spelling (with characters as they appear in materials). Searches can also use keywords converted into Roman alphabet letters using the ALA-LC Romanization Tables of the U.S. Library of Congress. Some materials are registered in Roman alphabet letters only. An index is created for them. So if the search has no hits with the original spelling, convert the keywords into Roman alphabet letters, and perform the search again.
How do I search for materials when I don't remember the title?
If your search returns too many hits, you can narrow it down with the [Classification] item from the [Refine Your Search] menu displayed on the left side of the search result list screen. In addition to using the classification item, you can also narrow down your search by material type, holding library, author, publication year, classification, subject, publisher, language, etc.
If the keyword search is unsuccessful, try using Search by Classification in the lower part of the [Nagoya Univ] tab.
For example, suppose you are searching for statistics-related materials. From Search by Classification, you can narrow down the search to the materials in the following fields by selecting and performing the search with
"4: Natural science -> 41: Mathematics -> 417: Probabilities. Mathematical statistics."
