Acquisition and Collection Development

Policy for Acquisition of Materials

A collection of materials forms the basis of all library services. The Library's collection policy which indicates how to develop those materials, closely relates to the library's mission and role.

The National Diet Library (NDL) has developed the Guideline for Acquisition of Materials and the Policy for Acquisition of Materials, and collects materials based on them.

The Guideline for Acquisition of Materials indicates the purpose and basic orientation of the NDL's collection.
The Policy for Acquisition of Materials describes requirements for acquiring materials specifically including the scope and priority of NDL's collection based on the Guideline for Acquisition of Materials.

How materials are acquired

The NDL acquires publications issued in Japan in accordance with the legal deposit system. Approximately 60 percent of books, magazines and newspapers the NDL accepts annually are based on this system.

In addition to the legal deposit system, the NDL collects materials by purchase, international exchange and donation. Open-shelf materials in each special materials room and foreign publications are acquired mainly through purchase. Foreign official publications are collected mainly through international exchange The NDL is designated as a deposit library by the United Nations and its specialized agencies, the European Union (EU) and the Organization for Economic Co-operation and Development (OECD) and accepts publications issued by each agency as deposited materials.

Separate Holdings of Materials

The acquired materials are held in three separate libraries, which are the Tokyo Main Library, the Kansai-kan and the International Library of Children's Literature (ILCL). The main holdings of each library are the following:

Tokyo Main Library

  • Deposited Japanese books, magazines, newspapers and electronic publications, etc.
  • Foreign books and newspapers
  • Some foreign magazines
    * Annual periodicals, some monograph series
  • Special collections

Kansai-kan of the NDL

  • Japanese books and some magazines
    * includes a second copy when more than one copy are deposited. The magazine collection mainly consists of indexed periodicals in the Japanese Periodicals Index.

Donation of Materials

The following guidance applies to donations from donors who are not publishers. For deposit of Domestic publications from publishers, please refer to "Request for Deposits" (in Japanese).

Acceptable Materials for donation

The NDL accepts materials which meet the following conditions as donations.

  1. Donated materials must meet the requirements of the NDL's Guideline for Acquisition of Materials and the Policy for Acquisition of Materials (in Japanese).
  2. In principle, donated materials must be materials that are not included in the NDL's collection. Since the NDL needs to develop an unbroken collection of each periodical title, it accepts donations of magazines and newspapers only to supply the NDL's missing issues except in the case of donations from publishers who come under the legal deposit system.
  3. Materials to be donated must be free of stains, tears, mold, and scrawls, and be in good condition to be used and preserved in the NDL.
  4. Japanese publications to be donated must be materials that are not expected to be deposited by a publisher due to the termination of its business.

The NDL may decide not to include donated materials into its holdings depending on their condition, etc. Please understand that in advance.
