The index consists of paper titles and authors sorted by subject. Each paper has been assigned to one of ten categories. The entry for each paper is preceded by a hyphenated numerical code indicating its subject, Proceedings volume number, and page number therein, i.e. 03-02-084 represents subject category "3", Proceedings volume number "2" and page number "84". Each Proceedings was actually published in the year after that of the meeting.
The current index covers the PTTI Proceedings from the 2nd (1970) through the 37th (2005). The first PTTI (1969) is an 8-page typed report.
Listings of later papers have links to abstracts and to pdf image files of the papers' texts, if available. pdf files can be read with an Adobe Acrobat Reader program, which is available free from www.adobe.com/products/acrobat/readstep2.html.
