of research outside the library. Plaintiffs’ affidavits stated that excess property, including legal materials, was subject to confiscation. And, while prisoners were allowed to keep several books in their cells, the affidavits suggested that they tended to deteriorate rapidly after their hard covers were removed, as required by prison regulation. We cannot say the district court committed clear error in not giving greater weight to the research opportunities outside the library. Fed.R.Civ.P. 52(a).
Defendants claim that plaintiffs failed to establish actual prejudice to any inmate case resulting from defendants’ alleged breach. Defendants assert such prejudice is a necessary element in establishing a case under Bounds. See, e.g., Twyman v. Crisp, 584 F.2d 352, 357-58 (10th Cir.1978); Bach v. Coughlin, 508 F.2d 303, 308 (7th Cir.1974); Isaac v. Jones, 529 F.Supp. 175, 179 (N.D.Ill.1981). The district court, however, found prejudice in the instant case. Assuming without deciding that a showing of prejudice is required, we cannot say that the court’s finding in this regard was clearly erroneous. Fed.R.Civ.P. 52(a). While the finding was derived from prisoners’ affidavits, the affidavits were admitted without objection and we cannot say they provided an insufficient basis for this finding.
Defendants also complain that the court’s findings were inadequate as they failed to specify whether the prejudicial claims involved constitutional issues. It is too late, however, for defendants to raise this issue. They did not make it below in their post-trial memorandum, nor did they file a motion under Fed.R.Civ.P. 59 asking the district court to modify its findings. See Welch & Corr Construction Corp. v. Wheeler, 470 F.2d 140, 141 (1st Cir.1972) (the district court was entitled to be told of any afterthoughts regarding errors in its handling of the case so that it could correct them if appropriate).
Defendants claim that the court erred in concluding that they had failed to rebut plaintiffs’ prima facie case as reqúired by Rich v. Zitnay, 644 F.2d 41. They assert that they conclusively showed that plaintiffs in fact had adequate access to the court, pointing to 66 suits maintained by DSU prisoners at the time of trial, including seven belonging to the named plaintiff, Richard Cepulonis. The district court, however, could properly discount this evidence since defendants have not indicated how many of the cases were begun when the inmates were in the DSU. From the record it appears that only three of the 66 suits were initiated during a DSU incarceration and of these three, two were begun by Cepulonis who was trained as an inmate law clerk.
The district court properly evaluated the steps taken by defendants to meet their Bounds obligation “as a whole.” 430 U.S. at 832, 97 S.Ct. at 1500. We find no reversible error.
III.
We turn next to the validity of the court-ordered remedy. Defendants say the district court’s remedial order was an abuse of discretion in three respects: it ordered a satellite law library; it required specific volumes which defendants label as “needless and excessive resources”; and it required that defendants provide law student assistance. As administrators of the prison, defendants contend they were entitled to greater deference in selecting a remedy. See Procunier v. Martinez, 416 U.S. 396, 404-05, 94 S.Ct. 1800, 1807, 40 L.Ed.2d 224 (1974).
Except in one respect, we find no merit in these contentions. Concerning the satellite law library, the district court “scrupulously respected the limits of [its] role,” ordering the creation of this facility only after the defendants, like the petitioners in Bounds, suggested it. 430 U.S. at 832-33. While there is a variance between the number of hours of access to the satellite library suggested by defendants (“at least 40 hours per week”) and the number ultimately ordered (56 hours per week), defendants do not now complain of this increase, but report they have voluntarily
