Articles from 1991,
1992, 1993 no. 1, and 1994 no. 3 are scanned images of the
original printed copies, while articles from 1995 and
1996 are PDF copies identical to the printed
versions. The remaining PDF copies appearing here were reproduced
from the final LaTeX source prior to printing; although the content in
these should be identical to that in the original paper copies of the
journal, there are small differences in line breaks and
pagination. This is due to changes between LaTeX 2.09 and
LaTeX2e, such as a change in the hyphenation algorithm. Full-text
searchability (or accuracy thereof) varies according to whether an
article was scanned or otherwise reproduced.
