The creation of a taxonomy for organizing and classifying a diverse array of materials such those that constitute the digital archive of Portuguese Experimental Literature is a challenging task for the researchers. Our system for organizing a selected corpus combines several typologies of classification, organized in two main areas: Materialities and Transtextualities.


The medium of the items, i.e., their material nature.

Performative > Readings and other artistic practices which are performed live with the possibility of audience participation: Audio recordings, Photographs, Video recordings of live Performances, Readings and Plays, as well as their Preparatory texts.

Planographic > Bidimensional works presented on flat surfaces using various techniques of inscription: Calligraphies, Collages, Drawings, Paintings, Printing, Digital Printing, Electrographies, Engravings, Letraset, Letterpress, Serigraphies, Stencils, and Typescripts.

Digital > Works produced by computational processes (generative, permutational, intermedia, etc.), as well as their related documents: Codes, Emulations, Preparatory texts, Printed texts, Recreations, and Rereadings.

Three-dimensional > Permanent or ephemeral three-dimensional works presented or installed in art galleries, buildings, parks, and other private or public spaces: Artists’ Books, Assemblages, Installations (Photographs, Preparatory Texts), Object-poems, Sculptures.

Phonographic > Works that were originally conceived as sound recordings, as well as related documents: Typescripts, Phonograms, Scores, and Preparatory texts.

Videographic > Works that were originally conceived as videopoems or other kinds of videoworks, as well as related documents: Storyboards, Videograms (Preparatory texts, Photographs), Videograms.


System of “relations” which includes reflexive manifestations of the symbolic systems involved.

Autograph MetatextualitiesTexts about the works and artistic practices produced by the authors themselves: Afterwords, Articles in Magazines and Journals, Articles in Newspapers, Books and Monographs, Chapters in Books, Critical Essays, Documentaries, Interviews, Introductions, Manifestos, Prefaces, Reviews, Theses and Dissertations.

Alograph MetatextualitiesTexts about the works and artistic practices produced by agents other than the authors: Afterwords, Articles in Magazines and Journals, Articles in Newspapers, Books and Monographs, Chapters in Books, Critical Essays, Documentaries, Interviews, Introductions, Prefaces, Reviews, Theses and Dissertations.

ParatextualitiesTextual elements that help to frame works and artistic practices: Catalogues, Covers, and Posters.

HypertextualitiesTexts that are explicitly derived from other texts: Citations – textual fragments from different sources -, Parodies and pastiches, as well as all texts that rewrite or explicitly refer other texts.

Remote idealizations and achievements; pioneers; aesthetic and material antecedents of experimental poetry. Included in this category are the visual texts of the 17th and 18th centuries – Labyrinths, Acrostics, Anagrams; but also some texts of Futurism and Dadaism that tended towards visuality.

Artist Books

A form of artistic expression that transcends traditional concepts of the book, through the creation of unique or multiple pieces. This experimental and conceptual approach treats the book as a work of art, exploring its materiality, structure, and interactive capacity.

Electrography and Copy Art

Intersemiotic form based on the creative exploration of the photocopier, problematizing the processuality and performativity of the instruments, machine and materials thus promoting a synthesis between the literary and visual arts that extends to the field of technology in its reflection on medial inscription, appropriation and reproduction.

Experimental Fiction

Form of narrative, prose, or fictional structure based in a non-linear organization of the signifiers, promoting the fragmentation of traditional narrative diegesis, as well as the use of unexpected relationships between writing, sound, and image – as well as its relationship at the level of meaning.

Concrete Poetry

Form of poetry based on the spatial organization and constellation of signifiers, leading to the abandonment of lines and stanzas as major rhythmic-formal units which are replaced by homologies and iconic relations between writing, sound, image and meaning.

Digital Poetry

Form of poetry that uses the computer as a creative machine, thereby promoting a symbiosis between artist and machine based on the exploration of combinatorial, random, multimodal and interactive algorithms. (Also known as: Cybernetic poetry; Electronic poetry; Cyberliterature).

Performance Poetry

Form of poetry based on multidisciplinary live action, thereby extending the poetic field to the expressiveness of the body and to the social and spatial context of the performed action. (Also known as: Perfopoetry; Poetry-performance; Performance; Poetic action).

Spatial Poetry

Form of poetry based on intersemiotic processes in which various sign systems (visual, audible, verbal, kinetic, performative) and materialities (three dimensional, objectual, media) are invoked and used in an expressive way.

Sound Poetry

Form of poetry based on the expressiveness of the phonetic aspects of language, as well as the vocal processes involved in sound emission, thereby extending the concept of poem to that of musical composition, usually associated with performative manifestations and live actions, but also produced either by audio recordings or by the visual representation of the score. (Also known as: Phonetic poetry).


Form of poetry based on the grammatical and communicative possibilities of the language of video, where the sign is iconized in a spatio-temporal action, articulating expressive elements such as the autonomous movement of shapes and colors, the integration of sound, and the interrelation space/time.

Visual Poetry

Form of poetry based on the dissolution of the boundaries between visual and literary genres, in which the poem becomes a hybrid and intermedia entity, thereby overcoming the exclusive use of verbal and typographic elements, which are placed in dynamic interaction with visual elements.


EXperimental POetry – Term proposed by  E. M. de Melo e Castro to contextualize the activities of Portuguese authors connected to visual, sound and concrete poetry from the 1960s to the 1980s.
