v
paramodulation for almost a year, but he didn’t hold it against me when I went back to text
handling. He also persuaded me that the number of items in a sequence must be conserved
under move operations. Paul Dourish came in relatively late as an advisor, and provided en-
couragement advice, and useful information. Mark Crovella and Steven Homer, the other
members of my committee have been more than usually indulgent of slipped schedules.
Various people have supported me financially during the writing of this dissertation, but
Paul Kahn and Dynamic Diagrams deserve special thanks for putting up with an employee
sometimes more virtual than real. They also let me use their facilities for my dissertation
work without complaint. Andries van Dam and the Tom Dean of the Brown University Com-
puter Science Department provided me with an office and access to their facilities for more
than a semester, at a time when I really needed one. Rosemary Simpson was a great office-
mate, and a great conversationalist on hypertext, life, computer interfaces and poetry. Long
before we were officemates, she also taught me what I know about the difficult craft of in-
dexing: little enough compared to her, but much more than most.
I’d also like to thank Joss Whedon, for indirect encouragement to fight on in the face of
certain doom, but not to get too serious about it; thanks also to B., G., W., X., C., and O. You
know who you are.
