I think Francis Pryors book, britain BC goes into the mesolithic and flint scatters, including microliths. Some good texts to look out for are by the Hampshire field club.
Because of the amount of archaeology round this way they are always finding flint tools and as such are always studied and recorded in minute detail. Often these books are available on ebay. Likewise other periodical archaeological journals are available from other digs from across the country, a very usefull resource for looking at microliths.
Its a shame that your not closer.
Where i live, Winchester, has sh1t loads of flint scatter.
You cant help but find flint tools or evidence of knapping, loads of debitage and if your lucky some real gems like barbed and tanged arrowheads. I have tubs full of bits and pieces that i've found over the years. I think many microliths are overlooked, not just because of size but because they dont look like your really well worked lithics.
Two other good books i have on flint in general are, Stone tools and society by Mark Edmonds and Prehistoric flintwork by Chris Butler. I find the American authors are kind of dry talking in their books.
Try emailing John Lord if there are any specific questions you have about flint or microliths.
In my opinion he is the best knapper in the world
A real nice bloke who im sure is a reincarnation of a prehistoric hunter.

I've waffled enough! Flint is a real passion of mine
