For them, I allowed them to use my libraries at no charge (about 10% of the code) and I charged them less than I would have if I included source.

For me.... Job security.

>Do they want source code for safety against your accidents or ability to re-sell (would include copyrights) ?

They already have exclusive resale on the assemblies. They are merging with another firm who wants to be able to review it.

I can probably give them the source code and still retain copyright.

>Do you want/think any further business with them ?

Yes

>Any chance of reselling as is to other customers ?

No

>Was it difficult to build/is recreating hard ?

Not too difficult, especially for me.

>Not enough info to give recommodations

Hopefully the above helps

>Also think whethter there is something in the code you would like to re-use in other projects - when I work in source included scenarios (most of the time) I have a clause in the contract giving me re-use rights to any codes not tied directly to the customers business consider something similar <g>.

Good advice.
