Name: Paulo Ney de Souza Title: Mathem. Sciences Pub. / U. C. Berkeley E-mail: desouza@math.berkeley.edu Talk: Long-time preservation strategies for TeX-sourced content. The amount of published material in the world has grown exponentially since Gutenberg's invention, with a rate of doubling every 7 1/2 years right now. Electronic publishing will only increase this rate, posing new challenges for the long-time preservation of records and usability for the future. TeX has changed us into our own typists and even graphics designers sometimes, but at the same time has provided the best strategy for preservation of scientific content we have. This talk will examine some of these strategies and how MSP - a non-profit scientific publisher - has used it to improve usability of journals over time. Paulo Ney de Souza
