For the first time in the year 1920, Iyyanki had started organising library Science training classes on behalf of APLA. In the year 1934 library wizards like Late Vavila GoplaKrishnaiah, Late Paturi Nagabhushanam and Late Sri Kalidindi Narasimha Raju got trained under the able guidance of Late Punyamurthula Rajasekharam and Late Kothari Rama Rao who were the true disciples of Late Sri Ranganathan. Later in the year 1941 Late Sri Paturi shouldered the responsibility of running the course by conducting training classes, for 4 week course of Granthalaya Pravesika and 2 week course of Granthalaya Visaradha all over the State. It was in the year 1966 that the AP State Government had recognised the certificate course in Library Science (CLISc) that was of 4 month Duration with class 10 as the minimum eligibility for admission into the course. There after it emerged into a 5 month course with Intermediate course as the minimum qualification for admission. Since 1989 APLA has been running courses with English and Telugu as media of Instruction, with two batches of intake, one in the month of June and the other in the month of December in a year. Certificates are issued to the qualified students by Department of Education, Government of AP. After the demise of Late Sri Paturi, the School is being run as Paturi Nagabhushan School of Library Science providing hands-on- experience and imparting technical skills to the needy.The School also organises  training programmes in MS Office, NewGenLib Library automation software etc.,
