Initially Carrega's poetry was inspired by Gabriele D'Annunzio, Dino Campana, Ceccardo Roccatagliata Ceccardi and Camillo Sbarbaro, but after discovering James Joyce, Ezra Pound, and E. E. Cummings he started experimenting with new linguistic forms based on the broadening of the semantic extension of the word.

[2][3][4][5] From literary positions, Carrega proposed the foundation of a new language integrating the alphabetic script with graphical elements of a different nature.

On the basis of the experience of Ana eccetera, in 1965 Carrega founded the magazine Tool with Rodolfo Vitone, Lino Matti, Vincenzo Accame, Rolando Mignani, and Liliana Landi.

[2][3][4][5] Like Ana eccetera, Tool aims to extend the area of writing through an analysis and restructuring of languages, but in a more practical way.

In April 1968, Carrega began publishing Bollettino Tool (Tool Bulletin), a new aperiodical magazine collecting news and examples of advanced poetry including works by Vincenzo Accame, Mirella Bentivoglio, Gianni Bertini, Henri Chopin, Ian Hamilton Finlay, Eugen Gomringer, Anselm Hollo, Emilio Isgrò, Marcello Landi, Ugo Locatelli, Arrigo Lora Totino, Stelio Maria Martini, Eugenio Miccini, Magdalo Mussio, Sarenco, Franco Vaccari, and Ben Vautier.

[2][6] The magazine continued the work of Tool, publishing documents of visual, concrete and total poetry including contributions by Vincenzo Accame, Luciano Caruso, Carlfriedrich Claus, Hans Clavin, Davanzo & Gunzberg, Antonio Dias, Jean Françoise Dillon, Jan Hamilton Finlay, Stelio Maria Martini, Rolando Mignani, Jean Claude Moineau, Ito Motoyuki, Hidetoshi Nagasawa, Joel Rabinowitz, Giose Rimanelli, Shohachiro Takahashi, and lastly Emilio Villa, who since the 1960s became a sort of "godfather" for Carrega.

In February of the same year Carrega founded the magazine Bollettino da dentro (Bulletin from Inside), in which he collected reports about his works.

In the same year he created with Ferrari and Claudio Salocchi the Centro di ricerca non finalizzata (Non-finalized Research Center).

[2] In 1982 Carrega supported the "Artescrittura" writing a short manifesto signed by Vincenzo Ferrari, Luca Patella, and Magdalo Mussio.

[5] In 1986 he collaborated with Sarenco, Eugenio Miccini, Lamberto Pignotti, and Stelio Maria Martini to re-found visual poetry.

In 1988 Paolo Della Grazia, collector of works of the verbo-visual movements since the 1960s, founded the Archivio di Nuova Scrittura (Archive of New Writing, ANS) with the help of Carrega.
