Notes
Price is questionable. The Internet Archive copy says "72499" in the barcode block on the back cover but in the top right corner is a price, slightly cut off, that looks like $24.95. However, a copy on eBay, https://www.ebay.co.uk/itm/325500166953, which claims to be a first edition says "51999" in the barcode block and has no price in the top right corner but does have a $24.95 price sticker covering some text in the top left corner. The eBay copy also has no 0-9 number line on the copyright page like the archived copy does and the ISBN on the back cover is written differently, 0-9672029-5-7 vs. 096720295-7.
