If I want to refer to all the different articles, theses, essays, books, etc. – published as well as unpublished/not yet published – that a scholar has produced, what word should I use? Can I use "academic works"? Or is there a better word here?
Scholarly Publications and Manuscripts.
Scholarly: involving or relating to serious academic study
Manuscript: an author's text that has not yet been published
It's perhaps better to distinguish between the published and non-published work. And you can't go wrong with "scholarly publications" and "manuscripts".
However, if you want to put them all in under one term, then go with —
Research Works or Scholarly Works.
Both "research works" and "scholarly works" are more common (and perhaps even better sounding) than "academic works". They are also broadly applied, meaning that they include work that hasn't been formally published yet.
Here is one definition of "scholarly work":
Scholarly work means all literary, dramatic, musical or artistic works, software, sound recordings, films or communication works produced by a Staff member and includes in relation to a Staff member’s research activities, any scholarly publications including books, text books, articles in scholarly journals research reports or conference proceedings.
While many of the other suggested alternatives in this thread are correct, it is perhaps best to go with a term that is commonly used for the intended purpose. This Google Ngram plot is quite informative:
There are a number of options
Academic works is suitably broad and academic output is perhaps even broader They should cover most of your suggestions and also patents and software.
Strictly speaking publications would include most of the completed work in the public arena including work posted on the web somewhere. They may interpret it more narrowly though.
As a piece of additional slightly off-topic advice if you are recruiting at a senior level you may want to ask for their best X outputs as otherwise you may get many pages.
The formal term for this is corpus, which means,
all the writings or works of a particular kind or on a particular subject; especially : the complete works of an author
This is the Latin word for "body", and you can use the English phrase body of work to mean the same thing.
Scholarly. I often see "scholarly writings" or "scholarly output" used for the corpus (see other answer) of someone's academic work.
In this guide we have divided the criteria for evaluating periodical literature into four categories:
News and General Interest
Sensational and Tabloid
My yearly evaluation form (as faculty at a US University) often uses the term "products" to refer to articles, letters, books, and the like. It may also include patents.
For instance, this US National Institutes of Health page describes how to include "research products" in your biographical sketch.
On the other hand, instructions for biographical sketches submitted to the US National Science Foundation as part of proposals uses the term "products" alone, without any further qualification.
Here's a page describing "Scholarly Products" of fellows at George Mason University.
