Vol 5: Issue 2 of 'The Origamian' for Summer 1965 included an article by Fred Rohm, 'On Bases', which argues that the concept of bases is unnecessary but also contains some interesting information about the way the concept of bases evolved. Only the latter is reproduced here:


Vol 5: Issue 4 of 'The Origamian' for Winter 1965 carried a follow-up article 'No Bases? For Shame?', also by Fred Rohm.
