Collections and Open Textbooks
The date beside each book title indicates the last time the textbook was updated in the B.C. Open Textbook Collection.
An update is usually a minor, backend adjustment that does not affect its content. When content is changed, this adjustment is noted on the Versioning History document listed on the textbook’s record page in the B.C. Open Textbook Collection. (We are in the process of posting Versioning History documents for each book in this collection.)
When a significant amount of content is modified, the new textbook files and web version are posted alongside the older files; a removal date (typically one month or more after the start of the next term) is noted by the older files.
