The Psychē Vault is your repository for articles that relate to Laboratory Information Systems (LIS) from the past. Psychē has been in business since 1976. We went into our archives and found some written articles by past employees and published articles that are no longer available on line. We believe these are still valuable and technically accurate today. In some cases, we have edited/updated some of the information. As we scour our old files, we will update The Psychē Vault periodically with ‘new’ old material.
