It is worth noting, as Henry pointed out above, a lot of TSR material is available as PDF, and has been for a while. I used some for my 3.5 game this weekend (and in PDF you can cut and paste and manipulate it all the more easily).
When WotC bought TSR, a lot of outstanding legal issues remained with Gygax and Arneson. WotC resolved those, and the first pdfs of older material started to be scaned and sold, or give away, shortly thereafter.
Of course there a difference between having a back catalog available on pdf, and putting newly printed books of a "defunct" edition on sale side by side with the current edition.
