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

1. Search from front page

There are three ways to search for authority data as shown in Figure 1, i.e. 1-1. Search by Keyword, 1-2. Search by Classification Numbers and 1-3. Search by Authority ID.


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”, or “Genre/Form Term” radio button beneath the input field. After selecting “Name”, users can search by Personal Name, Family Name, Corporate Body Name, Geographic Name, Uniform Title and Work. After selecting “Topical Name”, users can search by Topical Term and Subdivision. After selecting Genre/Form Term, users can search by Genre/Form Term.

1-1-1. Search Object

Search objects include Names/Titles, Variant Names/Titles as well as katakana 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 katakana form or romanized form, be sure to separate each word with a space.

Example:
ID:00054222
To search for the Name/Title “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 Name/Title “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 Name/Title “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 Names/Titles 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, Work, 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 Names/Titles with a representative classification of ME352, such as “阿賀川”, etc.

Example: Searching for ME* will find Names/Titles 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”, or “Genre/Form Term” radio button in the search window ((b) in Figure 2.). Users can search Personal Name, Family Name, Corporate Body Name, Geographic Name, Uniform Title and Work by selecting the “Name” button, and can search Topical Term and Subdivision by selecting the “Topical Name” button, and can search Genre/Form Term by selecting the “Genre/Form” button. However, the Classification Number is not added to Genre/Form Term.

1-3. Search by Authority ID

Figure 3: Web NDL Authorities Front Page (Authority ID Search) Screen

Links to the LCCN will be shown in the format such as “sh92002816 (LCSH)” or “gf2014026266 (LCGFT)” and users can access the relevant page of the LC Linked Data Service. IDs of BSH will be shown only when the synonym in the “Variant Term(s)” (Item No.7) matches the authorized heading of the BSH. The BSH is not available on the Japan Library Association’s website; thus, the relevant links to the BSH are not shown.
33 Sources

In these case, the links to the VIAF are not available, though the links are shown.
When the LCCN is recorded in Authority data, it will be shown in the format such as “n78095332 (LCNAME)”, and links to the relevant page of the LC Linked Data Service.
Also, when the form of the authorized heading matches with that of the BSH, the ID of the BSH will be displayed. The BSH is not available on the Japan Library Association’s website, thus, links to the BSH are not shown.

For the authority data used as Author Heading, the value “機械抽出典拠” is assigned to data extracted automatically, while the value “遡及入力典拠” is assigned to authority data cataloged retrospectively. For the authority data for materials in Asian languages, the value “アジア言語資料典拠” is assigned. For the authority data used as Subject Heading, the value “和図書不使用” is assigned to authority data which is not used in the bibliographic records of Japanese books.

For the Authorities of Geographic Name, Uniform Title, Work, Topical Term, and Genre/Form Term, links to pages in Japanese Wikipedia are displayed only when the same character strings as the authorized headings are included in the article title of the Japanese Wikipedia. Matching of character strings and creating links are done automatically; thus, the NDL does not guarantee the credibility of the information contained in Wikipedia.
