This one will be quick...
Wonder if anybody knows or remembers the title of the paper in which Karatsuba introduced his approach at Burgess's bound on character sums.
Thanks for your support.
EDIT. It might have been in "Sums of characters and primitive roots in finite fields". Since this appeared in Russian in Dokl. Akad. Nauk. SSSR, would any of you guys be so kind as to provide us with a review of the translation that, according to MathSciNet, appeared in Soviet Math. Dokl. 9 (1968), 755–757? Thanks again.
ADDED. I've been trying to get a copy of the corresponding issue of the Soviet Mathematics Doklady in the libraries to which I have access (real or virtual). It all has been to no avail. Does any of you know if there is a possibility to get a copy of it through the AMS? I recently took at look at ams.org to find out, but I didn't find info regarding the acquisition of back issues of the said journal.
