where some fine print is no longer legible. What I want is one that has only been reduced down to 300 dpi or so. How can I get that?

With a little help from okfn-labs (Open Knowledge Foundation), here is a script that works for my book:

#!/bin/sh pag=1 while true do hex=`printf "%04X" $pag` dec=`printf "%04d" $pag` if [ ! -s $dec.jpg ] then echo -n . wget -q -O $dec.jpg "http://access.bl.uk/IIIFImageService/ark:/81055/vdc_000000011B9A.0x00$hex/0,..." || break sleep 2 else echo -n : fi pag=`expr $pag + 1` done

That is the URL for one tile, but the tile that I request starts at 0,0 and is 10000 pixels wide, so it contains the full page 1800x2400 pixels, in full (pct:100) = 300 dpi resolution. This was faster than waiting for BL's webmaster's response on Monday.

In my case, I want the JPEGs. But if you want to use a book in Wikisource, you might want to create a Djvu or PDF bundle of all the JPEGs for the entire book.
