Kleine Schriften is a German phrase ("short writings" or "minor works"; Latin: Opuscula) often used as a title for a collection of articles and essays written by a single scholar over the course of a career.
These shorter works were usually published previously in various periodicals or in collections of papers (such as a Festschrift) written by multiple scholars.
Multi-volume collections may contain a scholar's minor or lesser-known book-length works as well.
The collection of a scholar who worked or taught internationally will often contain essays in more than one language; the multi-volume Kleine Schriften of Walter Burkert, for instance, includes work in German, English, and French.
This is particularly true of German philologists who emigrated in the 1930s, many of whom published much of their research in English or French; Friedrich Solmsen's three-volume Kleine Schriften,[2] in which English articles outnumber German, is an example.
