<p>Thanks Rob -</p>
<p><br>
</p>
<p>True - the equations are now usable, but slightly more blurred than my original PDF. Likewise, the figures are now OK but of slightly lower quality, which does NOT matter much for hand drawings. </p>
<p><br>
</p>
<p>I did note a lot of OCR misreads in the text. A careful proofing of the text took me 18 minutes and there are 25 errors, some not at all obscure, and about 13 of which I had to look at the original to see what they were supposed to be. (One was hard to
detect since it substituted an Rf for an Ri, a disaster). A full proofread/correction would take at least 30 minutes (188 eight-hour days for 6000 pages). And I wrote this! Almost certainly a volunteer would have more trouble and miss errors.</p>
<p><br>
</p>
<p>In the spirit of no good deed going unpunished, Rob, let me put you on the spot. Take your scan, find and fix the 25 errors. Let us know how easy/hard this was and the time it took, and show your results. </p>
<p><br>
</p>
<p>I will post the "solution" to the "find the errors" this evening if I get the chance.</p>
<p><br>
</p>
<p>Since there is no improvement in the figures/equations, and the text is a serious downgrade, tell me again (anyone) why an OCR/ebook is a good idea here. </p>
