Matthew Yes, I'm happy for you to OCR the book, but can I ask that whatever you get be made accessible from my web site, so there's one place people can go to find everything that's available?

- The ability to cut and paste passages into e.g. e-mail. - Availability for text-only access - e.g. for the vision impaired, or people on low bandwidth connections. - Possibility of re-typesetting it with e.g. LaTeX, to make nice-looking reprints on a laserprinter in your neighborhood. Basically, making the text (and not just pictures of it) available empowers its users in a general way -- not unlike publishing the source code to e.g. GHC.

It's just more convenient to read OCRed books than raster ones. Zoom without interpolation, possibility to convert to whatever format you like without much effort, etc.

You haven't seen the book in DjVu format :) BTW, DjVu can contain text, but I haven't learned proper spell yet :) I use free tools, so it may be difficult or impossible. PS/PDF generated from LaTeX is even better than DjVu, but it is very difficult to produce -- lot of hand work. If we will gather large command it will be possible. -- Ivan Boldyrev "Assembly of Japanese bicycle require great peace of mind."

I think even if we don't gather command that is large enough we should create the best version possible. It will be slower and more time-consuming, but who cares, the book is already 18 years old :) -- WBR, Victor V. Snezhko e-mail: snezhko@indorsoft.ru

LaTeX is macropackage for TeX; then yes :) -- Ivan Boldyrev "Assembly of Japanese bicycle require great peace of mind."

DjVu can contain the scanned image, ps or whatnot and a selectable invisible (at least by default) OCR version that will be used when selecting text.

windjview is not so quite bad... At least I don't have to run IE in order to use it :) For linux I heard about djvulibre, haven't tested it yet...

I have downloaded many books there one year and a half ago :) Have they opened it again? Didn't know, I will look there again... AFAIR, about a year ago they restricted downloading of djvu's by ip address that submitted original images. (history of djvus was available, but for 24 hours only...) -- WBR, Victor V.

There is a script. First you would only have to turn that set of raster images into a ps(.gz) or pdf document. I believe the site will turn those to djvu. I have done that with a few odd manuals, so I thought that might be one way. It is not guaranteed that the OCR will work or work well. For some things it does and for some it doesn't. But that is a simple way to access the non-free encoders and do the (or a) conversion with relatively little pain. Something to start with maybe.

...

Naturally. But as already mentioned, that means much more manual writing work (and/or some other OCR).

Certainly. This is *your* book. I'm not going to put it somewhere else.

As other already suggested, we can re-typeset you book with LaTeX. And produce even more compact and good-looking PDF document with searching, copy-pasting, printing, and so on. And you can use sources for new improved edition of the book. :)

It's going to be large project, what about creating new list? :) Can people at haskell.org help? P.S. I will upload DjVu version on Monday to Marnie's site. P.P.S. Perhaps, I can perform OCR myself if I will find a way to automate it. I will use high-res scans, which are much better than JPEGs for OCRing. Give me some days for experiments. I need help for converting to LaTeX and proofreading. -- Ivan Boldyrev

An OCRed version might help with my publishing the book via cafepress. The basic problem is that in order to create a pdf from the tiffs, I end up embedding the raw bitmap data (at a very high resolution for decent printing) and end up with a pdf that is way to big for cafepress to handle (even with bitmap compression). I have had some luck with autotrace and other tools to turn bitmaps into outlines, but not any that produced readable output of a suitable size. if the text were OCRed, then I could use outline fonts and considerably improve the printed quality and keep the file size down. I am not sure how easy it will be to integrate the output of the OCR software into an appropriate pdf, but I can try. John -- John Meacham - ⑆repetae.net⑆john⑈
