A workshop was held in Oxford, from August 24-26 1998, on the Hele-Shaw and problem and related issues. (Sponsorship from the London Mathematical Society and the European Journal of Applied Mathematics is gratefully acknowledged.) It took place 100 years after H.S. Hele-Shaw's paper in Nature, after which the problem is named, and 40 years after the celebrated paper by Taylor and Saffman ( Proc. Roy. Soc. 1958 ) which sparked off the fingering controversy.
As part of the preparation for the meeting, we prepared a bibliography of papers devoted to Hele-Shaw and Stokes flow problems. It is available for downloading from here.
