The money, from a donor who asked to remain anonymous, was donated through Philadelphia's Children First Fund, a nonprofit that supports the city's public schools. The donor "read the story in the paper" and reached out to the nonprofit about providing money to reopen the libraries, Gallard said.
"It's outstanding that we have individuals stepping up," he said, adding that the district was "extremely grateful" and surprised by the gift.
The contribution will cover the salary and benefits of the two librarians for the remainder of the school year, Gallard said Thursday.
Based on seniority, the two had been reassigned to other schools to do nonlibrary work. Gallard said he did not know if their library reinstatements would allow for the district to rehire any laid-off employees to fill their current positions.
He said the district would soon announce several projects intended to bolster library services.
"We are working as a district to actually find more sources of funding for libraries, especially in high-need schools," Gallard said.
As a result of this year's budget cuts, there were only 15 librarians left in the district. In 2011, the district had 65 librarians. In 1992, it had 176.
The loss of the librarian at Central was all the more painful since the school had opened a new $4.5 million library in 2005 funded by alumni.
Students visited Central's library 147,000 times last year.
