- submit to online which automatically downscales to 500 pix


If you want the best results for online images then I suggest to not doing it that way. This is a step where you get Moiré effects and in the downsizing process the image will be blurred. You also loose the chance to sharpen the resulting image and optimize the jpg compression level.

Nevertheless your images are very good.

Good point. For my next contribution I'll downsize it locally, upload and then put the higher res version back in my local, to see if that yields better results. Thanks for bringing it to my attention.

- scan at 600 dpi with a slightly rotated cover on the scanner.

Why rotated? Just asking as someone who always fiddles to absolutely  align the cover parallel to the scanner's edge. Just slabbing it on rotated and do this in "post production" ... have to ponder it.
Has it any other positive side-effects?

It helps against shadows at the edges.
But perhaps meyerd know another reason for the rotating.

It's more a feeling/experience that I get less Moiré this way, and as VirusPil said - it sometimes helps against shadow and reflecting effects.

Also, I never get it absolutely parellel so trying to do that would cost me much more time than rotate it on purpose and correct it later.   And - Photoshop has a great tool to do the correction. The cover is perfectly aligned after the rotation.

BTW - if I scan at 1200 dpi I try to get it parallel too because my impression is that it has no effects on such a high resolution.

The german "ct" had once an article about side effects on rotating raster images specialy in combination with scaling and they are not all bad, but I don't have it anymore and don't remember any details.

I've been recommended to scan in at least 800 DPI and that's what I nowadays do. Also work with the files in BMP format. That is uncompressed files. While I edit them (I don't use photoshop because I'm against altering the scans as much as I'm against altering any other data in the DB).

My current scanner is my multi function printer Canon MX-850.

But I've been recommended the Canon CanoScan 9000F which isn't too expensive but most importantly has gotten good reviews for being fast, reliable and accurate.
