juretriglav, speaking of problems to fix, I've found at least one the missing books that you're looking for, but unfortunately, it's not a freely downloadable or online version. I have also found a lot of useful information, but I'm still sifting and organizing it. To start off with, the "American Standards Association" otherwise known by the acronym "ASA" is the old name of the organization now known as "American National Standards Institute" ("ANSI"). They changed their name in 1966 (I think), but it's impossible to retroactively change every occurrence of the name, and some prefer one or the other, so let's just say standards are seldom standardized. The "American Society of Mechanical Engineers" ("ASME") is just one of many organizations that have worked with ANSI/ASA. It was ASME which originally worked on the standards you mentioned. The 1936 book you mentioned was tough to find since it does not have a standard number, and I think this indicates the time before ASA started creating and using standard numbers. Title: "Code of Preferred Practice for Graphic Presentation: Time Series Charts" http://books.google.com/books/about/Code_of_Preferred_Practice_for_Graphic_P.html?id=OZ3QHAAACAAJ http://books.google.com/books/about/Code_of_Preferred_Practi... Libraries http://www.worldcat.org/title/code-of-preferred-practice-for-graphic-presentation-time-series-charts/oclc/7164016 http://www.worldcat.org/title/code-of-preferred-practice-for... I'm fairly sure that's the 1936 book you wanted due to the notes here: http://searchworks.stanford.edu/view/1850233 http://searchworks.stanford.edu/view/1850233 ASA, Z15.2--1938 "This manual represents a rather comprehensive revision of the material issued in April, 1936, under the title, 'Code of preferred practice for graphic presentation--time-series charts'."--Foreword. The above is, the 1938 version you already have. I'll post the other info as soon as I get it sorted.
