In the early 20th century, there appears to have been an explosion in interest in Jiujitsu (originally spearheaded by Barton-Wright, of whom more here: http://en.wikipedia.org/wiki/Edward_William_Barton-Wright.
...and continued until the First World War temporarily reduced interest in hand-to-hand arts. For many of us accustomed to "mixed" fights in the modern context, it is interesting that there many matches between visiting Jiujitsuka and Western boxers and wrestlers. Since there were still quite a few styles of pre-Judo Jiujitsu making their way over, the offerings were fairly diverse in technique and approach...and several might still have a few tricks or concepts that would be useful today.
I've already managed to republish one of them, and I wondered if there are any particular manuals (or types of manuals) that you guys would like me to convert and republish.
