The original scans are large single-page TIFFs (or JP2? not

noticed, they're not taken from the PDFs.
The master images aren't available online, but I believe this is more
for reasons of scale and size than from a desire to keep them
protected - I know they've been made available to on-site researchers
without any restrictions. You'd be best off contacting the BL team if
you want access to the originals.
Of course I can't know if there is an "original" scan
in even higher resolution, but the one found in the
PDF has been reduced too far, down to c. 150 dpi,
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?
I have written to the BL webmaster. But there is
also a chance that someone else has been able
to scrape the BL website?
The item viewer for this book opens at
where "lsidyv36f7e082" apparently is its ID. Good.
The opening title page is
where the trailing "007" is the sequential number
of the scanned page. Also good.
If I right-click and "view image", I get the whole title
page in minimum zoom, but its URL is 430 kilobytes
long, starting with "data:image/png;base64,iVBORw".
So this is apparently the image (430 kbytes). As I
zoom in and "view image", I get similar sized (1-2 MB)
tiles of the whole page, at a higher zoom level.
in one place says "jp2level1=5", which might be an
indicator of what's behind.
The images found on Flickr are in the 300 dpi
resolution that I want, but they only cover the
illustrations, not all text pages.
