You're wrong. LSD: MY Problem Child (1979, Albert Hofmann) states that in the context of world distribution, Sandoz specifically chose to base the abbreviation of lysergic acid diethylamide on the German title. How are you going to state that LSD is based on lysergic... when you're also acknowledging that it's based on lysergsäurediethylamid. And how are you going to state the same thing when I pointed out that Sasha Shulgin, an ingenius chemist, indicated LAA as an abbreviation for lysergic acid amide? 
I don't know what you're getting at but I never said anything about the german root of the acronym.
I guess LSA is an easier convention than LAA because it gives you some indication as a casual user that it is related to LSD.
Sasha is right, but my comment was mearly on general guidelines that chemists use to make acronyms for compounds.
It may not have been explicitly accurate, but it is an observation that I've noticed after studying chemistry for the past three years.

Gotcha. I think I've observed that too. The world of abbreviations is kind of complicated because of their inherently limited nature. Whenever topics about lysergic acid hydroxyethylamide came up -- which is another chemical found in ergot; but it may get decomposed in the stomach* -- I would use the abbreviation, LAH, however when browsing PiHKAL recently I caught the title, LAH, and when I looked it up I realized that it referred to lithium aluminum hydroxide. So I should stop using LAH when I speak of lysergic acid hydroxyethylamide. Whenever professionals speak of this chemical, they simply write it out in full. I've never seen it abbreviated, although if it was ever found to be of significance I'm sure they would come up with something cute.
Another thing I'd like to point out is that Pickard abbreviated lysergic acid 2,4-dimethylazetidide as diazedine. I find it to be significant that he gave it such a name because it shows that he was conscious of the fact that LSD is actually a unique title and that LSZ would be unjustifiable. All the professionals seems to be aware of this, for example one Peter Webster actually gave a speech about ergot at the 2006 LSD Symposium and he used the title ergine for lysergic acid amide.
And thanks for the compliment in post #21272653.

Not a problem, quality responses deserve it. 
That's interesting that you mention the LAH thing.
The other day I was going over the Ziegler-Natta catalyst mechanism and I noticed that they abbreviate methylaluminoxane as MAO just like the mono-amine oxidase enzyme.
The logic behind acronym assignment is a big mess in the chemistry and molecular biology world, quite a bit of overlap.
That's why IUPAC nomenclature rocks, gets straight to the point. Starts to devolve once you begin naming enzyme complexes and proteins though.

"LSA" may well relate to the German title but you know that "LSA" has never been written in any professional academic publications.* It's amusing how the one publication I have where lysergsäureamid is used does not use "LSA" as an abbreviation, although the abbreviation the article does use is probably inaccurate.

Source: Solms, H. 1956. Chemische Struktur und Psychose bei Lysergsäure-Derivaten. Praxis, 45:746.
I will provide some background information on the abbreviation used in the article. This abbreviation is based on the Sandoz code name, LA-111; this code name was created based on lysergic acid and was applied to lysergic acid amide before lysergic acid amide was known to be a naturally-occurring chemical.

*With the exception of a few recent publications that picked up the "LSA" slang name.
I'm not arguing that abbreviations were most likely lost in translation and ambiguity. However, the fact remains that Hoffman was a swiss chemist who spoke german. Ergine (lysergic acid amide) is actually far different than lysergic acid, which is just a carboxylic acid.

That much is obvious.
All translations aside the commonly accepted abbreviation for Ergine in the scientific community is LAA,
the abbreviation LSA likely came from recreational users who wanted to signify it's similarities to LSD.

That, and the fact that at the beginning of the 20th century, german was the language of science. Basically all journals and research were published in german and translated afterwards. Säure = acid and I'm sure the ambiguity doesnt stop there. As far as Im concerned, LAA and LSA are the same thing. As english is now the dominating language of science, it doesnt surprise me that the currently accepted abbreviation is LAA.

You should have read through Da2ra's post more carefully, even in german publications Lysergsäureamid is abbreviated as LA.
Has nothing to do with german -> english translation, also the idea that german was the language of science is not true.
It may have been true for chemistry leading up to the 1950's, but if you wanted to get nit-picky latin and greek would technically be the language of science.

There might be obscure German publications where it's abbreviated as LSA (although there are very few publications about LAA), but the point is that unlike LSD, LAA wasn't distributed around the world as LSA. If it was, there would have been sanction to call it LSA. Solms 1956 abbreviated it as LA because its code name was LA-111. It wasn't until 1963 that LAA was discovered to be a natural product, when it was discovered in ergot-infected morning glory seeds. This was a sensational discovery, but the sensation about the natural relative of LSD died off quickly as the pure compound was never mass produced and there are various issues with using it in the form of morning glory seeds, at least not without doing a somewhat sophisticated extraction. It could have developed a good reputation, however:
Grof: Have you actually tried the ololiuhqui yourself? [oh-lowlee-uh-kee -ed.] Hofmann: Yes, I did. But, of course, it is about ten times less active; to get a good effect, you need one to two milligrams. Grof: And what was that experience like? Hofmann: The experience had some strong narcotic effect, but at the same time there was a very strange sense of voidness. In this Void, everything loses its meaning. It is a very mystical experience. -- When I discovered lysergic acid amides in ololiuhqui, I realized that LSD is really just a small chemical modification of a very old sacred drug of Mexico. Stanislav Grof Interviews Dr. Albert Hofmann (1984). MAPS Bulletin 9.2 (Fall 2001): 22–35. http://www.maps.org/news-letters/v11n2/11222gro.html
Ololiuqui corrected as ololiuhqui NOTE: Although the spelling ololiuqui has gained wide acceptance and is now the commonest orthography, linguistic evidence indicates that this Nahuatl word is correctly written ololiuhqui. Note by R.E. Schultes included in the following essay: R. Gordon Wasson. Notes on the Present Status of Ololiuhqui and the Other Hallucinogens of Mexico, Botanical Museum Leaflets, Harvard, vol. 20 (1963)
The effective dose of lysergic acid amide is 1 to 2 mg by oral application. Albert Hofmann. The Road to Eleusis: Unveiling the Secret of the Mysteries. 1978. R. G. Wasson, Albert Hofmann, and Carl A. P. Ruck. Page 10. DOWNLOAD
Also I just made two really good posts about ergot in this thread for anyone interested. Mainly about yielding purified extracts.

This is the era I'm referring to. Before WWII the majority of breakthroughs in modern physics and chemistry were centered around the german language. Max Planck, Albert Einstein, Hendrik Lorentz, Wolfgang Pauli, etc. Germany and surrounding areas were the hub of science. That being said, yes, much of the common nomenclature was founded on latin origins.
Saying that the abbreviation LSA has nothing to do with the german spelling just isnt true...whether or not it was published 
Im sure it had something to do with, not matter how small it is.

I'm pretty sure a rule of language is that you abbreviate things in your own language unless you're authorized to do otherwise. LSD was a universally accepted title and it originated from the large pharmaceutical corporation that invented it. LSA doesn't even appear in any academic publications prior to 2009.

On top of that, if theres not a standard abbreviation aside from the IUPAC you'll likely come across several variations. When i was researching sodium salts of substituted cyclopentadienyl anions there wasnt a whole lot of literature available. Nearly every publication I found used different abbreviations for the same compound.

Then wouldn't all abbreviations for chemical compounds be an arbitrary designation?
If they change according to what language you speak then it's function is just as a short reference to the much longer IUPAC name.
I'd be very interested in knowing if there is such a thing as a field of etymology focused solely on IUPAC nomenclature.
