With this issue, "RiDE" begins a new occasional series of short informational pieces on archives in the field of drama and theatre education and applied theatre and performance. Each instalment will include summaries of several collections of significant material in the field. Over time this will build into a readily accessible annotated directory of archival resources, which will be updated as necessary and available via the "RiDE" website as an ongoing resource for researchers, teachers and practitioners. This first instalment includes descriptive summaries of, and access arrangements for, The Dorothy Heathcote Archives (at Manchester Metropolitan University), The Peter Slade Collection (at the University of Manchester) and the archives of the Belgrade Theatre in Education Company (Coventry). Future instalments will cover as wide a field as possible and will include, for example, the Children's Theatre Collection at Arizona State University; the SCYPT Playscript Collection at Leeds University; and the TIE/TYP collection from London Drama at the Central School of Speech and Drama. The aim is to include not only the established, fully catalogued and well known collections, but also the lesser-known, possibly quite small and "emergent" collections (e.g. those which exist in one location but have yet to be systematically catalogued); and significant collections contained within larger archives. The authors therefore invite contributions to this series from the "RiDE" readership. The next instalment (planned for 17:3) will be devoted wholly to the "Child Drama Collection at Arizona State University"--probably the largest repository in the world documenting the international history of theatre for children and young people back to the sixteenth century.
