Sivatattvaratnakara is a Sanskrit (or Samskrit as the master prefers) poem written by Basavaraja in 1698-1715 period.
Keladinrpavijayam is written by a Brahmin court poyet Linganna. It details the political history of the Ikkeri kingdom, including incursion by the Bijapur kindom, and the final defeat against Hyder Ali in 1763.
Portuguese documents (Moncoes do reino, Instrucoes, Pazes-E-Tratados) are kept at Archivo Secretaria Geral do Governo, Panjim and Lisbon. Copies are available at Indian Historical Research Institute in St. Xaviers College, Bombay.
Note that when the book was initially published (1957), Goa was still a Portuguese colony. For this reason, I expect that the original documents would probably not be found now in Panaji.Dutch documents in Batavia Dagh Register deal with relations between the Dutch and the Ikkeri Nayakas.
English Factory Records and correspondance from Tellicherry, Karwar and Bombay relate to commercial relations between the English and the Nayakas.
Accounts of foreign travellers like Della Valle, Peter Mundy, Dr. Fryer, Pinkerton and Abbe Carei are also cited.
The Persian work Ferishta is a glorified account of the Bijapur kingdom's millitary campaigns.
Peshva Daftars provide details about Marathi incursions into the Carnatic.
A number of native manuscripts and chronicles are also cited, as being preserved in the Government Oriental Manuscripts Library in Madras:

The word 'KAIFIYAT' is an Arabic term and it simply means a narrative. This name was given by Colonel Collins Mackenzie to history, legends and myths of villages he visited and about which he collected historical documents. In India such local tracts were generally known under the name STHALA PURANAS.
