This Website first went live in August 2001 - 33 years after the first ISDOS Working Paper. The first set of pages is basic. Much material is to be added and this will be a rolling program.

An early goal is to put the PSL Language into the public domain. This will be done from this website. Copyright is owned by Geoffrey Darnton. Free use of the language will be granted subject to an open public licence that will be published on this site.

Another goal is to provide an archive of historical material or abstracts of ISDOS and PSL/PSA related materials. The copyright in these may rest with others and further use will need to be arranged directly by the user.

Major revisions are documented in a revisions table.

As will be obvious to most visitors to this site, I know what I want to say, but I confess to having extremely poor web design skills! Any volunteers to help with producing a nice design will be very welcome indeed. Volunteers please to g d a r n t o n @ p s l p s a . c o m .

If you have previous links with PSL/PSA or related products, and would like either an email address via pslpsa.com, or links to any of your own material, please let me know, and I'll set it up.
