The Defence Ministry, in a statement posted on its website, said the information, including on those already freed, is available at locations in the north of the country as well as in the capital Colombo and in the southern town of Galle.
The move comes amidst pressure by Tamil political parties in Sri Lanka as well as international groups and governments who had urged the Sri Lakan authorities to either charge or release the war detainees.
A visiting European Parliament Delegation had recently called for a fair trial for long-term detainees in Sri Lanka.
Chair of the European Parliament Delegation for Relations with countries in South Asia, Jean Lambert, had said that the EU Parliament’s position on long-term detainees in Sri Lanka is that they should be either charged or released.
Several hundreds of suspected Tamil Tiger rebels and other political prisoners are in Sri Lankan prisons, some of whom have not faced trial or a charge years or months after they were arrested.
Human rights groups have said that the government gradually released many, but not all, of the more than 11,000 suspected Tamil Tiger suspects detained at the end of the war.
