+This page summarizes PDP-11 documentation that was useful in creating [PDPjs](/modules/pdp11/).  In most cases,
+these documents came from the PDF Document Archive at [bitsavers.org](http://bitsavers.org),  in the [/pdf/dec/pdp11/](http://bitsavers.informatik.uni-stuttgart.de/pdf/dec/pdp11/)
+directory.  If a PDF was not searchable, it was "OCR'ed" before being archived below.
