Foerster's critical editions and his Wörterbuch present a large number of variants.

In Luttrell and Gregory's edition of Cliges, the apparatus "contient principalement les variantes essentielles" (p. XXXVII); that of Busby's edition of Perceval offers variants "en principe complètes, à quelques exceptions près" (p. LXII).

The Projet Charrette sites present the images of seven of the eight Lancelot manuscripts.

For Yvain, readers will find a semi-diplomatic, continuous transcription of seven manuscripts by P. Kunstmann on the LFA site, which also contains a synoptic transcription (with modern segmentation but without punctuation) by K. Meyer of all the manuscripts and fragments.

We also note that the Nouveau Corpus d'Amsterdam presents partial transcriptions of some Yvain and Perceval manuscripts on line.
