Overview

All items submitted to cIRcle for archiving must be delivered to cIRcle in digital format. In line with the recommendations of the UBC Library Digital Preservation Subcommittee, cIRcle uses an open source digital preservation system called Archivematica, which has preferred file formats in order to ensure files are stored long term.

Only digital files may be submitted to cIRcle. DVDs and CDs that require digital transcoding (conversion to an acceptable format) will not be accepted. Printed documents will not be accepted.

Exclamation

Although cIRcle can technically accept all file formats, it is strongly recommended and important to submit files that are in one of the preferred file formats, in order to ensure long term accessibility and preservation of the content.

This list is not exhaustive; please contact the cIRcle Office at circle.repository@ubc.ca if you have any questions.

File Sizes

Please ensure each of your files are no larger than 2 GB in size. Please note that an item record can hold multiple files, with each file up to the size limit.
