              SUPER-MEMO WORLD'S DATABASE BANK

All users of SuperMemo software are kindly invited to send in their
SuperMemo databases. Upon no-cost evaluation, the qualified databases
will be added to the SuperMemo World's Database Bank and distributed
along other SuperMemo World's products.
All authors of qualified databases will receive their royalties on
terms agreed with SuperMemo World.
We can only evaluate databases created in English (except for bilingual
databases if one of the languages is English).
The preferrable domains are: English, bilingual databases to learn
English, sciences, medicine, economics, political and social sciences,
geography and history.
We will not accept databases that may have aggressive military
applications or can promote socially undesirable attitudes.
Small, self-contained databases (50-300 items) will receive preferrence,
although large databases can also be accepted if they satisfy the
requirements of:
   - knowledge structuring
   - universal applicability
   - language standards
   - systematic ordering of items within the database etc.

All users have their databases formatted for their own use only, i.e.
databases are not transferrable between persons of a different
registration number.
If a user wishes to pass his database to another person, and the
individual format is an obstacle, he may send his database to
the SuperMemo World Database Bank.
SuperMemo World will convert the database to the universal format that
is compatible with all SuperMemo programs of the given line.
Such a database will be added to the Database Bank and distributed
worldwide with 50% of the net profit returned to the author of the
database.
We can only convert databases created in English (except for bilingual
databases if one of the languages is English).
We will not convert databases that may have aggressive military
applications or can promote socially undesirable attitudes.
