II. Services for the National Diet
The NDL provides legislative research services and library services for the National Diet members and others connected with the Diet.
1. Legislative research service
The Research and Legislative Reference Bureau of the NDL conducts research on politics, economy, and social affairs inside and outside Japan using the NDL collections and databases. The total number of researches conducted by the Research and Legislative Reference Bureau in FY2006 was 44,199. Among them, researches conducted for Diet members and Diet-related people are shown in <Table 5>. Total number of research cases based on requests increased by 2.2 times in the last decade (see <Chart 2>).
In FY2006, we enhanced and strengthened the system in the Research and Legislative Reference Bureau to divide the tasks appropriately, based on the Guidelines for Services for the National Diet which we formulated in FY2005. For information provision, we released Index Database to Japanese Laws, Regulations and Bills (early Meiji period) (Japanese only).

2.Library services
The Detached Library in the Diet (DLID) is a small but front-line library
providing services to the National Diet. It is located on the fourth floor of
the Diet building inside the tower. OPAC of DLID (Japanese only) is also available
for the Diet members via the DLID website. In September of FY2006, we introduced
a service for Diet members which delivers materials and copies to the Diet Members’ Buildings
and collects loaned items from them.
<Table 6> shows the library services provided at the DLID, and <Table7> shows
the library services provided for the National Diet by the NDL (except by DLID
and the Research and Legislative Reference Bureau).
