CD to Web database migration

[Dennis Brantley]

Cross posted - apologies.

First of all, I will state that I am a vendor so please bear with me as
I try to ask some questions.  Respond directly to me if you like and I
will summarize for those interested.

I am curious about the migration of database access from CD to
web-access.  At the high water mark, how many CD databases did your
library have?  How many now?  How many were replaced with web access? 
Is future growth likely to be primarily web databases only?

For those databases migrated to web access, what were the compelling
reasons?
Cost?
User Interface (browser)?
More current?
Desktop application support associated with CD?
Easier to implement? How?
Less user education?
Publisher has indicated that CD will not be published in future?
Other?

Are there negative consequences, such as:
Speed of web vs LAN?
Less sophisticated search tools?
More difficult to validate authorized users, particularly offsite users?

Which web-enabled databases use proprietary search engines, and which
use a browser, or both?

Do any publishers that support a browser interface to their data provide
the ability to mount a local copy of the data, whether on CD or hard
disc?

Does Z39.50 compatibility figure into the equation?

Comments about what's missing?
