In this issue Next issue: LaTeX Work Bench Thanks Editorial: Best of PracTeX In this issue This fourth issue of 2008 of  PracTeX includes a selection of some of the most interesting papers published in the journal, from its beginning in 2004 through 2008. Each editor selected a few articles thought to be the best from that period.. A note about the missing issues for 2009: The editors took the year 2009 off, and there will be no issues 2009-1 through 2009-4. We also decided to change from four issues per year to just two. Thank you and enjoy this issue! Paul Blaga Next issue Theme: LaTeX Work Bench Editor: Francisco Reinaldo The next issue of  PracTeX will bear the number 2010-1 and it will appear soon.
