Extensive indexes

Those who prefer more specific queries, have at their disposal two elaborate indexes, facilitating quick and effective searches:

The subject index guides the user to material on specialised subjects not covered by the classification scheme [e.g. Al-Azhar, mawlids, railways], and also to items relevant to one subject but classified under another.

The name index lists not only authors, but also editors, translators, reviewers and personal subjects. So researchers interested in, for instance, Ibn Khaldun or Muhammad Iqb?l or the Ayatollah Khomeini can quickly find publications both by and about them.

The on-line and cd-rom editions enable advanced and efficient searches across the indexes.
