Go to the "Main ECO Codes" cut and paste the entire list into a WP such as Open Office or MS Office (NOT Notepad or WordPad) and shrink it down as much as possible, unless someone actually finds a better answer. I think this is doable if you're familiar with using WPs although the double sided printing to save pages may get tricky if your output is on only a portion of the regular 8.5' x 11" sheet.
I'm sure I could do this if i was interested (which I'm not) although I dunno how many pp, even double-sided, would be required.

Would like the A-E Opening book codes but many take 50 pages to run off. Do you know of any that are in a like a pocket or real small size, or very interesting print format?
