Scientific and technical developments have further aided research on the collection. It is now possible to conduct word-searches through a millennium and a half of Greek literature and through most of the published Greek documentary papyri via CD-ROMs issued by the Thesaurus Linguae Graecae of the University of California and by the Packard Humanities Institute. Difficult script on a papyrus can be enhanced by more and more sophisticated video imaging, including infra-red and ultra-violet examination, to complement the binocular microscopes the project has had for over thirty years. Facilities and experience are exchanged with the recently-established Centre for the Study of Ancient Documents in Oxford, and now there is an Oxyrhynchus Home Page on www.csad.ox.ac.uk/POxy/.
