TDL offers several training classes for DSpace and other software/services we offer. They are a good way to get in depth information on a particular topic; the sessions typically last for a day - in some cases half a day. You’ll be able to get all your questions answered about a particular topic.
This last Wednesday after getting back from vacation I co-taught the “DSpace Customization” class with Steve Williams from UT. I think the class was a great success, here are the slides we used for the class.
