Index of Documents

Several papers have been written for the group at the U3A in Bath, and this is an index of all the most important ones. Note that the dates are when they were presented, or written, and this area of technology moves quickly, so details may well be out of date. However, the historical notes are of course still valid up to the date of creation.

Documents are in PDF format unless otherwise stated.
