Stuart Wayne Tompkins seeks to appeal the district court’s * March 17, 2008, 2008 WL 717719, order denying relief on some but not all of the claims raised in his 42 U.S.C. § 1983 (2000) complaint and the court’s June 4, 2008, 2008 WL 2311408, order denying several motions filed by *977 Tompkins. This court may exercise jurisdiction only over final orders, 28 U.S.C. § 1291 (2000), and certain interlocutory and collateral orders, 28 U.S.C. § 1292 (2000); Fed.R.Civ.P. 54(b); Cohen v. Beneficial Indus. Loan Corp., 387 U.S. 541, 69 S.Ct. 1221, 93 L.Ed. 1528 (1949). The orders Tompkins seeks to appeal are neither final orders nor appealable interlocutory or collateral orders. Accordingly, we dismiss the appeal for lack of jurisdiction. Tompkins’ motion for appointment of counsel is denied. We dispense -with oral argument because the facts and legal contentions are adequately presented in the materials before the court and argument would not aid the decisional process.

DISMISSED.
