Collate was developed by Peter Robinson for the collation, analysis and publication of texts preserved in multiple witnesses. The current version of the software can handle up to 2000 versions of a different text. Collate has a regularization tool which can be used to produce a file containing word equivalences without altering the original transcription files. The software uses a light tagging system which can, at a later stage, be converted to XML. Collate can produce output files for paper-based editions or electronic publications. The following are examples of projects which are currently using Collate:
- Canterbury Tales Project, directed by Peter Robinson.
- Monarchia Project, directed by Prue James.
- Commedia Project, directed by Prue James.
- Cancioneros Project, directed by Dorothy Severin.
- Nestle-Aland 28 (the electronic version of the Nestle-Aland Greek New Testament), based at the Institut für neutestamentliche Textforschung INTF.
- Parzival Project, directed by Michael Stolz
