Reference

I can't find any trace of reference [a1]. Can anyone help? Richard Pinch (talk) 22:23, 21 January 2017 (CET)

Here is something relevant: Francis Bonahon Preprints Available; the second item:

• New Geometric Splittings of Classical Knots, and the Classification and Symmetries of Arborescent Knots, with Larry Siebenmann. This is the revised version of a famous unpublished manuscript, about 300 pages in its current form. After 30+ years, it may be published as a book reasonably soon (stay tuned!). PDF file (6 MB)
