   SUMMARY ORDER

Appellant Paul Robert Germano, pro se, appeals from four district court orders: (1) the August 20, 2010, 2010 WL 3417869, order denying his motion for the appointment of counsel; (2) the March 28, 2011, 2011 WL 1214435, order partially granting the Appellees’ motion to dismiss; (3) the March 30, 2011, 2011 WL 1233254, order denying Germano’s June 2010 request for a preliminary injunction directing the Ap-pellees to return his confiscated books; and (4) the April 6, 2011 order granting the Appellees’ motion to depose Germano in prison. We assume the parties’ familiarity with the underlying facts, the procedural history of the case, and the issues on appeal For the reasons that follow, we have determined that we lack appellate jurisdiction over the appeal.

Although neither party addresses this Court’s jurisdiction, “we have an independent obligation to consider the presence or absence of subject matter jurisdiction sua sponte. Joseph v. Leavitt, 465 F.3d 87, 89 (2d Cir.2006). In general, a district court order is appealable only as a final order under 28 U.S.C. § 1291 or Rule 54(b) of the Federal Rules of Civil Procedure, as an order relating to an injunction or other matter encompassed by 28 U.S.C. § 1292(a), as an interlocutory order certified under 28 U.S.C. § 1292(b), or as an order falling within the collateral order doctrine. See Whiting v. Lacara, 187 F.3d 317, 319 (2d Cir.1999). A final order is an order by the district court that “ends the litigation on the merits and leaves nothing for the court to do but execute the judgment.” Coopers & Lybrand v. Livesay, 437 U.S. 463, 467, 98 S.Ct. 2454, 57 L.Ed.2d 351 (1978) (internal quotations omitted). The collateral order doctrine is limited in its application to “trial court orders affecting rights that will be irretrievably lost in the absence of an immediate appeal.” Richardson-Merrell, Inc. v. Roller, 472 U.S. 424, 430-31, 105 S.Ct. 2757, 86 L.Ed.2d 340 (1985).

Under Rule 54(b), a district court may direct entry of judgment as to some, but not all, of the claims or parties by “expressly determining] that there is no just reason for delay.” Fed.R.Civ.P. 54(b); see also Ruffolo v. Oppenheimer & Co., 949 F.2d 33, 35-36 (2d Cir.1991). Here, the district court’s March 28, 2011 order dismissed all of Germano’s claims against twelve defendants and some of his claims against the remaining defendants. That order, however, permitted some of Germa-no’s claims to proceed. In so doing, the district court did not direct the entry of judgment as to the dismissed defendants and made no express certification, as required by Rule 54(b), that there was no just reason for delay. Accordingly, we are without jurisdiction at this time to consider the merits of the district court’s partial dismissal. See Clark v. United States, 624 F.2d 3, 4 (2d Cir.1980).

Turning to the district court’s March 30, 2011 order denying Germano’s request to force the defendants to return his confiscated books, 28 U.S.C. § 1292(a)(1) provides that “the courts of appeals shall have jurisdiction of appeals from ... [i]nterlocu-tory orders of the district courts ... granting, continuing, modifying, refusing or dissolving injunctions, or refusing to dissolve or modify injunctions, except where a direct review may be had in the Supreme Court.” Injunctive orders are appealable under section 1292(a), however, only if they affect the substance of the plaintiffs basic claim. See Henrietta D. v. Giuliani, 246 F.3d 176, 182 (2d Cir.2001) (“To qualify as an ‘injunction’ under § 1292(a)(1), a district court order must grant at least part of the ultimate, coercive relief sought by the moving party.”) “Procedural rulings which are incidental to the resolution of the substantive issues are not within the scope of this provision.” Shakur v. Malcolm, 525 F.2d 1144, 1147 (2d Cir.1975). As we have explained:

An injunction may be defined as an order that is directed to a party, enforceable by contempt, and designed to accord or protect some or all of the substantive relief sought by a complaint in more than temporary fashion. It is to be contrasted with an order by a court that regulates the conduct of the litigation, which is not considered an injunction for the purposes of appellate jurisdiction, even though punishable by contempt.

Frutiger v. Hamilton Cent. Sch. Dist., 928 F.2d 68, 72 (2d Cir.1991) (quoting Gon v. First State Ins. Co., 871 F.2d 863, 865-66 (9th Cir.1989)).

The district court’s denial of Ger-mano’s request for an order directing the defendants to return his confiscated books was “an order ... that regulate[d] the conduct of the litigation” rather than one designed to protect the substantive relief sought in Germano’s complaint. Frutiger, 928 F.2d at 72. Germano’s request was “incidental to the resolution of the substantive issues” raised in his amended complaint. He asserted in both his original request in the district court and in his brief on appeal that his purpose for seeking the return of his confiscated books was to perfect his arguments about the treatment he received for his mental illness, an issue material to the development of his Eighth Amendment medical deliberate indifference claim. The district court’s denial of this relief, therefore, is also not appealable under section 1292(a). See Shakur, 525 F.2d at 1147 (order denying plaintiffs request to force a correctional facility to give attorney-type visiting privileges to three paraprofessionals assisting with the prosecution of plaintiffs civil case found not appealable).

Finally, neither orders denying the appointment of counsel nor orders compelling discovery are independently appeal-able in the absence of a final judgment. See Barrick Grp., Inc. v. Mosse, 849 F.2d 70, 72 (2d Cir.1988) (“Generally, orders denying or compelling discovery are non-appealable.... ”); Welch v. Smith, 810 F.2d 40, 42 (2d Cir.1987) (“[A]n order denying a plaintiff the appointment of counsel to represent him in pursuing the merits of a suit under § 1988 may not be challenged separately by a direct appeal.”).

Accordingly, because we lack jurisdiction to review any of the orders from which Germano appeals, this appeal must be, and therefore is, DISMISSED for lack of jurisdiction. 
      
      . We note as well that Germano’s April 15, 2011 notice of appeal is untimely as to the district court's August 20, 2010 order. See Fed. R.App. P. 4(a)(1); Brown v. Eli Lilly & Co., 654 F.3d 347, 354 (2d Cir.2011) (noting that a timely notice of appeal is a jurisdictional requirement).
