This is a lot of three Microsoft Windows 2.0 software development kit manuals. Specifically includes the programmers reference, the programmers learning guide, and a volume that includes programming tools, application style guide, and Microsoft Windows extensions.

These are in good condition overall, but there is discoloration of the pages and the inside covers shows some spots.  These are limited to the two inside cover pages in the front and the rear. Please see the pictures for details. This may be spots from nicotine or minor mildew.

These will be very usable but they are far from perfect.

These will ship by USPS media mail.
