At the end of the year the data would be cumulated into an annual volume, the sales of which would help to support the project. The high quality of indexing is the result of these contributions from workers based in the countries in which the periodicals are published. As would be expected, the means formerly employed to record the data, reproduce it and convey it to subscribers have undergone radical changes throughout the years. The original service, which involved sending out batches of 10.000 cards to each subscriber every year, was replaced by microfiches in 1983. 10 years later the microfiches were in turn replaced by a biannual CD-ROM service.
Every update replaces the previous one.
The annual volumes continue to be produced, now with the advantages of computer typesetting. To order the CD-Rom, print out this FORM . Published from 1979 till 1990, containing TV-related periodical indexing data. A publication of the FIAF Documentation Commission, this 220 pages volume describes documentation collections, held in 125 of the world's foremost film archives, libraries, and educational institutions in fifty-four countries. The Directory is organized by country, indexed by city and special collections.
