Otfried,
You seem to presume C-H is depending only on its CD-ROM sales. In fact,
they have migrated to the Web - on a server which works faster than the
CDs - and there is a cost for continuing access. That yields a continuous
revenue stream without the need for more CD sales, and this permits
receaching institutions which might spring dollars for web access without
purchase of CDs.
Nor do I believe that enough scholars would spring $450 for a copy to
assure the firm the <i>desired<i> costs + profit. Too many academics tell
me
these days that they cannot afford books & depend increasingly on their
library.
