We have now uploaded on Academia the early English and German versions of the "Humphrey Visual Field Primer". These little books are really well written and beautifully illustrated - real gems. In contrast to some of the later editions of the "Primer", the early ones are strong on basic principles and fundamentals. Thanks to Leander Böhme for digitising these.
Für den deutschsprachigen Raum brauchen wir gute Literatur. Thieme, Springer, where art thou? Der Schlaf der Vernunft bringt die Ungeheuer hervor...(und umgekehrt, wenn es nur nicht so lustig wäre).
