The TCI Library was created by Remco Enthoven and is maintained by Telephone Collectors International, a non-profit organization, as a public service. It supports our goal of helping to preserve the history of telephony -- particularly fragile paper documents that may otherwise be lost to posterity. It is supported by members through dues and by the generous donations of funds and files from other sponsors and site visitors. All work is done by members, who unselfishly volunteer their time.
Don't expect to find every document you might want here. Even though we have a lot of documents, there are many, many more that we need to find and add.
The Library has grown quickly over the last few years. Many documents were added with few keywords. Searching for info is not always as simple as we might like. Note that we have three different search options on the Search menu. Each has its strengths and weaknesses. Try them all.
Our limited volunteer staff adds keywords largely based on specific user feedback. Let us know if you are having problems finding something, and we’ll see if we can help locate it in the Library.
Please help make the Library better.
- Send any suggestions on keywords to be added to specific entries,
- Contribute scans of documents in your collection and
- Volunteer time to help add keywords and improve document descriptions.
If the Library has helped in your research, we hope you'll support our effort as a TCI member, Library volunteer or by making a donation.
Telezonia and Teletrainers
Check out the newly added 1964 Teacher's Guide for Telezonia -- the Bell System's program to educate elementary school students in how to use the telephone. The program started in 1950 and used several generations of Teletrainer hardware. Paul Fassbender and John Novack have collected BSPs for many of them. Find them with a simple search for "teletrainer"
Bell Laboratories Record Cumulative Index
Chuck Hensley has compiled a complete index covering material in all BLR issues! (September 1925 - December 1978)
This monumental 422 page work was completed by scanning individual index documents, appending them into a single file and sorting them by keyword. It is fully searchable by keyword, making research a lot more effective. Thanks Chuck!

Bell Laboratories Record articles
There are a lot of scans from Chuck Hensley's collection of BLR magazines in the Library.
You can easily navigate to the BLR folder by starting at "Browse the Library" in the menu bar and selecting Document Repository / Catalogs, Manuals... / Western Electric / Bell Labs Record.
HINT: A neat way to see articles on a topic in chronological order is to go to Search / Basic Search and enter a BLR subject query using a keyword or keywords describing a topic of interest. This is great for researching the evolution of products or services. For example:
- BLR Dialer
- BLR Picturephone
- BLR PBX
- BLR Payphone
- BLR Speakerphone
Experiment with other subject keywords.
(If you enter these queries in the search box in the upper right corner of the window, the results will be sorted with Newest additions first. You can change ordering to alphabetical to sort the results in chronological order.)
We now have a comprehensive index with hotlinks to articles in the Bell System Technical Journals published from 1922-1983, provided by Sam Etler. Follow the BSTJ Archive link under "Browse the Library" in the black menu bar above.
Hints for using the TCI Library
