The National Library of Wales in Aberystwyth is reopening on Saturdays, it has been announced.
It closed at the weekend nearly a year ago because it had to save £250,000, but having made savings it now intends to open its doors again from 8 May.
Library president Dafydd Wigley said there had been support from the public to provide a service on Saturdays.
But it will be limited. Collections will be available, but material will have to be ordered in advance.
The library's shop, café and meeting rooms will also be available to the public.
Mr Wigley said: "There was a lot of support from the public to re-consider and reopen the library on Saturday and calls on the assembly to give priority to maintaining funding for the library.
"Re-opening has been a priority of ours, and in conjunction with the assembly government, we have managed to make savings and re-structured so that we are now in a position to offer a service to readers, tourists and locals."
Plans to shut at the weekend were announced in November 2008.
The library blamed a "steady decrease in its budgets over recent years", but its funder the Welsh Assembly Government disputed this.
