 There's lots of links here already to tutorials and encyclopedia entries about many of the notions we'll be dealing with.
 
+Many of these links are to Wikipedia. You can learn a lot from such articles,
+so long as you remember they may sometimes mislead or make mistakes. However, I
+hope at this point in your education you'll have learned to be a guarded reader
+even of authoritative treatises by eminent authors. So you shouldn't need any
+Wikipedia-specific warnings.
+
+For most readers, many bits of reading we point you to will be hairy in one way
+or another. It may be aimed at audiences with more programming experience; it
+may be aimed at audiences with specific logical background you don't yet have;
+it may be aimed at audiences familiar with technical areas in linguistics you're
+first encountering. Or perhaps several of these at once. We hope you will
+already have mastered the skill of leveraged reading: getting what you can out
+of an article you don't fully understand, so that you can discuss it with the rest of
+the group and hopefully get to a point where you can read it again and
+get more out of. (Rinse and repeat.)

+invited talk, *19'th Symposium on Principles of Programming Languages*, ACM Press, Albuquerque, January 1992.
+<!~-	This paper explores the use monads to structure functional programs. No prior knowledge of monads or category theory is required.
+	Monads increase the ease with which programs may be modified. They can mimic the effect of impure features such as exceptions, state, and continuations; and also provide effects not easily achieved with such features. The types of a program reflect which effects occur.
+	The first section is an extended example of the use of monads. A simple interpreter is modified to support various extra features: error messages, state, output, and non-deterministic choice. The second section describes the relation between monads and continuation-passing style. The third section sketches how monads are used in a compiler for Haskell that is written in Haskell.~->

Meijer, editors, *Advanced Functional Programming*, Springer Verlag, LNCS 925, 1995. Some errata fixed August 2001.
+<!~-	The use of monads to structure functional programs is described. Monads provide a convenient framework for simulating effects found in other languages, such as global state, exception handling, output, or non-determinism. Three case studies are looked at in detail: how monads ease the modification of a simple evaluator; how monads act as the basis of a datatype of arrays subject to in-place update; and how monads can be used to build parsers.~->
