Nein!

Dafür gibt es 2 gute Gründe.

1) Bedeitet a.m. "Vormittags"
2) müßte man 'mentioned above' oder 'see above' statt 'above mentioned' abkürzen.

Je nach Kontenxt würde man für diesen Zweck ibid. schreiben

Do you mean "idem" DW (the same as previously mentioned)? "Ibid." means "in the same place".

Ibid.
(abbreviation for the Latin, ibidem, or "in the same place") Ibid. is used in footnotes/endnotes to represent the repetition of a reference when two notes in a row refer to the same source.

Definitions of idem on the Web:

* (L 'the same') Often abbreviated to id., it denotes the same word or name or title already referred to.

* The same. Also a trade name for a paper producing copies without carbon paper.

* Ibid (Latin, short for "ibidem," "the same place") is the term used to provide an endnote or footnote citation or reference for a source that was cited in the last endnote or footnote. It is also abbreviated "Ib." in legal documents. It is similar in meaning to "idem," abbreviated "Id."

Well, I thought I meant ibid, but of course that could only mean "siehe oben" in certain cases. Perhaps you're right, but I have to admit that I wasn't familiar with "idem". From the last definition above it seems to be pretty much the same, though.

The source
(and yes, strangely enough, the definition of idem does finish off with a definition of ibid.)

Hmmm. Don't think you would use either in a text passage anyway. I can only remember it from, for example:

J. Bloggs, JOC 1979 (34) 4-8
idem, JAC 1980 (35) 18 (i.e Joe Bloggs as mentioned)
ibid, 50-52 (i.e. same reference but pages 50 to 52)

In text I think you're stuck with writing out "above-mentioned" or "the above ..." etc.
