eBay's purchase history only covers the current year and either of the two most recently completed calendar years.
What information are you trying to find? Some info may be found on your feedback page -- including the item title and seller username if feedback was exchanged.
You can request a report of your older transactions here:

Reports take a week to generate, and then you must use the resulting link within another week before it expires. Transaction data is quite basic: item name and number, date, price, shipping, seller username. No pictures or descriptions.
