Sometimes... it makes you go "argh".

There is that article that I am writing (or, rather, re-writing according to the suggestions made by the reviewers). It's about, who would have thought it, the never-ending spinning experiment. And it is driving me nuts.

Why? Well, for one thing, I am trying really hard to get some proper plots out of the thing. Which, according to my instructions and due to the help of a lovely person who knows R should be no problem... but my modules keep crashing, not reacting, or not giving me the results I need.

And then there's the citations. I have read in gazillions of publications that "thick yarn is made with heavy spindles"... and of course I did not take that as a note. And now I need to add a few more references to this, and it seems I cannot find them anymore. This is probably due to the fact that many of these books or articles were quite basic, or not typical scientific reference literature - but it makes it not easier to re-find them. So I will be shamelessly blegging:
Do you know a book (preferably something like a beginner's guide) or an (archaeological) article about hand-spindles and hand-spinning where heavy spindles are linked to thick(er) yarns? Please tell me in the comments. That would be really helpful.
