The following shows how to operate (especially, how to search) and each screen display.


1. Search from front page | 1-1. Search by Keyword | 1-2. Search by Classification Numbers | 2. Search Result Screen | 2-1. Search Result List Screen | 2-2.Detailed Information Screen


1. Search from front page

There are two ways to search for authority data as shown in Figure 1, i.e. 1-1. Search by Keyword and 1-2. Search by Classification Numbers.


Figure 1: Web NDL Authorities Front Page (Keyword Search) Screen


1-1. Search by Keyword
Click the “by keyword” tab shown in 1-1 to enter the search keyword in the input field and start searching.
Users may select the “All, Name”, or “Topical Name” radio button beneath the input field. After selecting “Name”, users can search by Personal Name, Family Name, Corporate Body Name, Geographic Name and Uniform Title. After selecting “Topical Name”, users can search by Topical Term and Subdivision.

1-1-1. Search Object
Search objects include Authorized Headings and References as well as kata-kana form and romanized form of them.
If you search for personal names and cannot find any results, be sure to insert a space between the family name and given name.
Search results are affected by spaces between words. Expressions in the search index have spaces between words. If your search does not find any items of interest by using kata-kana form or romanized form, be sure to separate each word with a space.

Example:
ID: 00054222
To search for the heading “夏目, 漱石, 1867-1916 (ナツメ, ソウセキ, 1867-1916)”
The word without spaces “ナツメソウセキ” (NatsumeSouseki) does not find any items of interest.
The word with spaces “ナツメ ソウセキ” (Natsume Souseki) does find items of interest.

1-1-2. Normalization of Characters
Characters shown below are normalized and are considered identical in searches. Thus, a user may input either form and get the same search results.
    • Hiragana/Katakana, Alphabet (Upper/Lower cases, Full-/Half- width), Numbers (Full-/Half- width), Basic Latin/Extended Latin
    • Upper case “ツ”, “ヤ”, “ユ”, “ヨ”, “ア”, “イ”, “ウ”, “エ”, “オ”, “ワ” and lower case “ッ”, “ャ”, “ュ”, “ョ”, “ァ”, “ィ”, “ゥ”, “ェ”, “ォ”, “ヮ” are recognized as the same letter (same for hiragana).
Examples:
Searching for “ギリシャ” also finds “ギリシヤ”.
Searching for “カッテ” also finds “カツテ”.
    • Voiced sound mark (゛)/ Semi-voiced sound mark (゜)/No voiced sound mark・No semi-voiced sound mark
Example:
Searching for “パリ” finds both “パリ” and “バリ”.
    • “ヴァ”, “ヴィ”, “ヴ”, “ヴェ”, “ヴォ” / “バ”, “ビ”, “ブ”, “ベ”, “ボ”
Example:
Searching for “ヴァイオリン” also finds “バイオリン”.
    • Variants of Kanji
Example:
Searching for “渡辺” finds “渡邉” and “渡邊” as well.

The following codes are not recognized.
Half-width apostrophes (‘), plus signs (+), periods (.), grave accents (`), or hyphens (-)
Full-width center dots (・)

Example:
ID: 00564245
If you want to search for the heading “遺跡・遺物”, searching for “遺跡遺物” or “遺跡・遺物” will both retrieve the same results set.

All half-width and full-width punctuations or symbols other than the above are handled as spaces. An AND search is conducted for character strings before and after a space.

Example:
ID: 00276855
If you want to search for the heading “AT&Tベル研究所”, you can also get the same results by searching for “AT△Tベル研究所”, where the △ indicates a space. Searching for “ATTベル研究所” does not find any items of interest.

1-1-3. Prefix Search
Adding either a half-width asterisk (*) or full-width asterisk (*) to the end of a search string conducts a prefix search.

Example: Searching for “日本歴史*” finds the headings that start with “日本歴史”, including “日本歴史学会” and “日本--歴史--1945--1952”.

1-1-4. Restriction
Due to system restrictions, a keyword that contains only a single kanji in combination with other characters will often fail to find meaningful hits from the authority data.
Examples: Searching for “さいたま市” does not find “さいたま市立中央図書館”, because the search index contains “さいたま” and “市立” as separate words.
Alternatively, searching for “さいたま” or “さいたま市立” does find “さいたま市立中央図書館”.

1-2. Search by Classification Numbers

Figure 2: Web NDL Authorities Front Page (Classification Number Search) Screen

The Classification Number Search allows users to search for authority data for Geographic Name, Uniform Title, and Topical Term by representative classification numbers from the Nippon Decimal Classification (NDC) 9th Revised Edition, NDC 10th Revised Edition or the National Diet Library Classification (NDLC) , which are assigned to the authority data. Users can choose either from a dropdown list ((a) in Figure 2) to search. In addition to searching for exact matches, users can do a prefix search by adding either a half-width asterisk (*) or full-width asterisk (*) at the end of the search string.

Example: Searching for ME352 will find headings with a representative classification of ME352, such as “阿賀川”, etc.

Example: Searching for ME* will find headings with a representative classification that starts with ME, such as “雨” (representative classification of ME129) or “阿賀川” (representative classification of ME352).

Users may select “All”, “Name”, or “Topical Name” radio button in the search window ((b) in Figure 2.). Users can search Geographic Name and Uniform Title by selecting the “Name” button, and can search Topical Term by selecting the “Topical Name” button.
