- The almost mandatory book by Hartshorne,
- lecture notes by Daniel Huybrechts,
- Positivity in Algebraic Geometry pt 1 by Robert Lazarsfeld,
- Compact Complex Surfaces by Barth, Hulek, Peters and van de Ven,
- Complex Algebraic Surfaces by Arnaud Beauville,
- Baragar's paper discussed by Erik in lecture 12,
- Shimada's paper on the algorithm discussed by Dino in lectures 13 to 15,
- (a less serious one) here is what 'regular' people in Belgium and the Netherlands think of when you mention 'K3'. For an example of their quite annoying music, consider opening this YouTube movie.
- probably more to come.
