The number of stone inscriptions which have been found in Sri Lanka to date is over 4000. But these inscriptions are of different types. Considering their locations and their appearances, for the ease of studying, they are classified as follows:
Polonnaruwa galpotha inscription, the Mihintale slab inscription and the Thonigala inscription are examples for the slab inscriptions.
Badulla inscription and the Katugahagalge inscription are classified under pillar inscriptions. Cave inscriptions are found to be the oldest type of inscriptions. They are inscribed below the drip ledge of caves. These are seen almost in every cave belonging to the early period. At the beginning the inscriptions had two or three short lines containing the information about donations made to bhikkus. But after the 2nd century A.C according to the Mihintale inscription, Jethavanaramaya sanskrit inscription and Badulla pillar inscription the inscriptions have got lengthy descriptions. The inscription on Abhayagiri terrace has 16 long lines. The inscription on the terrace of Dakunu Vihara is spread out on 17 slabs. Some inscriptions were produced in multiple copies. Thirteen copies of the Vevalkatiya inscription of Udaya IV were placed in various part of the Rajarata. After the 10th century A.C these have become more descriptive because they contained appreciations made for some kings.

After the 10th century A.C these have become more descriptive because they contained appreciations made for some kings. When considering the letters and the symbols used in the inscriptions, inscriptions written in different languages have been found. It is clear that people have used brahmi letters, Pali and Sanskrit to write these inscriptions. Here from these inscriptions information can be gathered in order to get a knowledge about the evolution of the sinhala letters and the development of the language, grammar rules, and structure.
Donations
"දෙවනපිය මහ රක්ඛභ බරියය බකි උපසික වරුණයණ"-The cave of Waruna Datta Upasika the sister of the queen of King Devanampiyatissa
"බඩගරික පරුමක කිස පුත පරුමක අශඩ ශුතඟ ලෙණෙ"-The cave of Ashanda gutta These caves say the names of the people who made and donated the caves to the bhikkhus for their use. Because of these people could know the donar and his/her title, genealogy, profession, and status. When studying these inscriptions, it is clear that donation was not limited to kings and royalty, but also people of different classes. These form of inscriptions written in pre- and post-brahmi letters have been found in places such as Rajagirikanda and Aanaikkuttikanda.
Economy
A single inscription can yield information on many different subjects. These inscriptions provide information about the economy of ancient Sri Lanka. Information like the old trade methods, the occupations and the economic stability of people, ownership of lands, types of taxes which cannot be extracted from the literary resources can be found from them. For example, Godawaya pillar inscription says about the taxes levied in the Godapawatha Harbour, Badulla Pillar Inscription says about the administration of an old market and Perimiyankulam inscription provides information about old trade grades and industries.
Society
Stone inscriptions give facts about the spread of Buddhism, spread of the civilization and spread of the stone inscriptions. Moreover they help us to understand how far the kings had power over the country. Inscriptions reveal information that is not written in literary sources. For example, Kaduruwewa inscription says about five generations of ministers. When taking about the religious background, inscriptions provide information about bhikkhus, various religious beliefs and customs, administration of the temples, the lands owned by the temples and privileges. Mihintale pillar inscription, Abayagiriya sanskrit inscription and Kaludiya pokuna inscription tell about the administration of the temples and Sithulpawwa inscription says how the income gained by the judiciary was given to the temples. One of the most important uses of these inscriptions is that the information contained in these are contemporary to a particular incident. Therefore the information written in the literary sources can be proven by the inscriptions.
