A large number of linguists concluded that establishing databases for linguistic work is a must. Ramifications in linguistics, applied linguistics, educational linguistics, sociolinguistics and psycholinguistics necessitate, according to linguistic researchers, linguistic communities to be founded. These findings account for the results that support the idea of specialized bibliographies, subject indices, author indices, etc. Taken together, these results weigh strongly for writing this book (in its two parts) that attempts to simplify the mission of the researchers in the field of linguistics and save their time, money and effort to find the sources they are looking for fast.
