[[Michael Danos]] and [[Johann Rafelski]] edited the ''Pocketbook of Mathematical Functions'', published by [[Verlag Harri Deutsch]] in 1984.<ref name="Danos_1984"/><ref name="REV_182_18"/> The book is an abridged version of Abramowitz's and Stegun's Handbook, retaining most of the formulas (except for the first and the two last original chapters, which were dropped), but reducing the numerical tables to a minimum,<ref name="Danos_1984"/> which, by this time, could be easily calculated with [[scientific pocket calculator]]s.<ref name="REV_182_18"/> The references were removed as well.<ref name="REV_182_18"/> Most known errata were incorporated, the physical constants updated and the now-first chapter saw some slight enlargement compared to the former second chapter.<ref name="REV_182_18"/> The numbering of formulas was kept for easier cross-reference.<ref name="REV_182_18"/>

A digital successor to the Handbook, long under development at NIST, was released as the “[[Digital Library of Mathematical Functions]]” (DLMF) on 11 May 2010, along with a printed version, the ''[[NIST Handbook of Mathematical Functions]]'', published by [[Cambridge University Press]].<ref name="NIST_2010"/>
