linking record to pdf or jpg

Is it possible to link a record to a pdf/jpg/tiff, etc.? I would like to be able to link scanned versions of old conference programs, etc., to a record. Would this be through the digital object section or can you only enter metadata here?

Re:linking record to pdf or jpg

Yes, see the Digital Object module. In the AT User Manual, see chapter 10 (p. 155-)

And further info (post AT 2.0)is at:
