The specialist who study inscription are called epigraphist. Some of the problems that these epigraphists faced while gathering information and deciphering it are as follows:-

i) The letters on the inscriptions were faintly engraved thus reconstruction of the words became unsure.

ii) Some of the inscriptions were not in proper condition thus few words and pieces were missing thus leaving them uncertain about the meaning of the words used in the inscription and understand its timeframe.

iii) Several inscriptions have been discovered but not all of them were able to be deciphered, translated and published.

iv) Many of the inscriptions are not found in the proper shape and in a complete form thus providing us with only the faction of what is inscribed.

v) Not everything that this inscription has recorded is important enough that we consider politically and economically strong.
