An officer with Stockholm county police told AFP: "We have this report and now we will make an investigation on this report."
The officer said investigators would examine the dossier in closer detail on Tuesday morning.
Valentin Bart, a writer and filmmaker, uncovered the images on a visit to the National Library of Sweden in Stockholm in November 2008.
He told AFP that accessing the images had been fairly straightforward with the library making no background checks.
"I had to show my ID card and become a member of the library. I then wrote to the library's legal counsel to tell him why I wanted to access the material. I'm doing research and want to expose this dark period of pornographic history."
On gaining access to the library's archives, Bart came across magazines with titles such as "Bambino" and "Fifteen".
"They showed children posing in many pornographic situations... It was disgusting," he said.
Bart, who worked in a pornographic bookshop in the 1970s, explained child porn was legal in Sweden between 1971 and 1980.
Sara Bengtzon, a spokeswoman for the National Library, said Swedish law obliged them to collect all printed material published for its archives.
"We collect all materials printed in Sweden because there is a law that says we have to do so," she said.
Bengtzon said the library felt Swedish law was unclear on whether to allow the public to view such material and only clamped down on access after Bart brought it to their attention.
"We have a lawyer looking into this right now and he is making a report. It will be ready by June 8."
She added: "This is a very delicate issue and we have now closed admission to this collection."
Anyone who produces, purchases or is in possession of pornographic images featuring children risks up to six years behind bars in Sweden.
Bart questioned why the library should not be prosecuted for possessing images of child pornography.
"Is it possible for a state institution to be above the laws here in Sweden?" he said.
