82 (9th Cir.1977). To the extent the inmates have preserved this issue, we conclude that the decision by the district court should not be reversed.
The existence of an adequate law library does not provide for meaningful access to the courts if the inmates are not allowed a reasonable amount of time to use the library. See, e.g., Ramos v. Lamm, 639 F.2d 559, 583-85 (10th Cir.1980), cert. denied, 450 U.S. 1041, 101 S.Ct. 1759, 68 L.Ed.2d 239 (1981); Williams v. Leeke, 584 F.2d 1336, 1340 (4th Cir.1978), cert. denied, 442 U.S. 911, 99 S.Ct. 2825, 61 L.Ed.2d 276 (1979); Twyman v. Crisp, 584 F.2d 352, 358 (10th Cir.1978) (per curiam) (Twyman). However, the Constitution does not guarantee a prisoner unlimited access to a law library. Prison officials of necessity must regulate the time, manner, and place in which library facilities are used. Twyman, 584 F.2d at 358. The fact that an inmate must wait for a turn to use the library does not necessarily mean that he has been denied meaningful access to the courts. See Nadeau v. Helgemoe, 561 F.2d 411, 418 (1st Cir.1977).
Prison officials constantly revise schedules to meet the needs of a changing prison population. Our review, however, is of the schedule of access at the time the compliance order was filed. Our review of the record indicates that the Prison’s library was open for a minimum of 11 hours each day. We consider that to be an adequate amount of total library access time. The Prison cannot be expected to keep the library open 24 hours a day, even if doing so would improve the inmates’ ability to conduct legal research. The schedule of access allocated blocks of time during each day to the different classes of inmates and permitted inmates at various custodial levels to use the library at specified times upon request.
Furthermore, we take judicial notice of the fact that the new library facility can accommodate up to 40 inmates at one time, which undoubtedly will provide for a significant increase in library access. In Xdoe, the district court specifically found that a “very workable and well planned schedule for use of the library is presently being used.” To the extent this question is not moot and was properly preserved, we conclude that the Prison’s schedule of access was being complied with and that it provided inmates with reasonable access to the library.

The inmates also contend that the district court erred in finding that adequate paper and supplies and a sufficient number of functional typewriters were available at the Prison. The existence or condition of the library’s typewriters is irrelevant, as the Constitution does not require that they be made available to inmates. See, e.g., Twyman, 584 F.2d at 358; Wolfish v. Levi, 573 F.2d 118, 132 (2d Cir.1978), rev’d on other grounds, 441 U.S. 520, 99 S.Ct. 1861, 60 L.Ed.2d 447 (1979); Tarlton v. Henderson, 467 F.2d 200, 200-01 (5th Cir.1972) (per curiam). In any event, the record indicates that functional typewriters and adequate paper and supplies were provided.

As their final argument, the inmates contend that the district court abused its discretion in not issuing a permanent injunction against the Prison. The decision to grant or deny an injunction will not be disturbed on appeal unless there is a clear abuse of discretion. SEC v. Arthur Young & Co., 590 F.2d 785, 787 (9th Cir. 1979). We will not find an abuse of discretion unless the inmates demonstrate that there was no reasonable basis for the district court not to issue the injunction. Id.
The inmates maintain that the district court should have issued an injunction because of the serious threat that the Prison will return to former unconstitutional practices after this litigation is over. The record, however, does not support the inmates’ argument. At the compliance hearing, the district court specifically found that the Prison had complied with the plan that was approved by the court. Addition
