Where can I find books on text analysis?

Fairclough's line of study, also called textually oriented discourse analysis or TODA, to distinguish it from philosophical enquires not involving the use of linguistic methodology, is specially concerned with the mutual effects of formally linguistic textual properties, sociolinguistic speech genres, and formally sociological practices. The main thrust of his analysis is that, if —according to Foucaultian theory— practices are discursively shaped and enacted, the intrinsic properties of discourse, which are linguistically analysable, are to constitute a key element of their interpretation. He is thus interested in how social practices are discursively shaped, as well as the subsequent discursive effects of social practices.
