Your home page states:
All of the programs found here run on IBM AS/400, iSeries and System i. They are open-source and free for personal and commercial use.

but the license file of tifflib states that you reserve the copyright.

Under what terms may your port of TiffLib be distributed commerically?

Below is contents of TIFFLIB/LICENSE(LICENSE). Though I put "Acknowledgment:" at top of the document, I will not (should not) insist that I own the copyright of libtiff.

The libtiff Inherits original copyright and it also can be found at "Acknowledgments and Other Issues" page.

:!: Note that TIFF2PDF included in my distribution has different copyright (GPL). Newer libtiff has its own TIFF2PDF program but it is not the one I ported.

Hope this clarifies copyright issue.

I would like to include your port of LibTiff in commercial software. I have already included the LibTiff copyright in the documentation. May I include your port of LibTiff if I include with the LibTiff license your license file?

I'm not the specialist of copyright law.
IMHO, it is enough to mention that AS/400 port is done by me and distributed at my site (or can be obtained from CD-ROM which is bundled to my book).
