It reports the development of an enhanced library OPAC prototype through integration of language analysis tool and book reader in the retrieval interface. Language analysis or text analytics is considered as one of the components of language documentation and when integrated with library OPAC can extend supports to analyse corpus of the retrieved document in terms of word/phrase frequency, term circus, term links, term context etc through visual representation in a single-window along with the other datasets generally expected in a typical library OPAC. The open source software based integration mechanism is tested with English and Bengali as mainstream languages and a Unicode-compliant Indian official tribal language Santali (Ol Chiki script) as minority language.
