Welcome to the TCI Library
TCI welcomes new members of all ages with an interest in telephony - Vintage Phones, Switching, History, etc.

The TCI Library 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 donation 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 (over 23,000), 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 of documents or cash (tax deductible in the US).

In addition to documents in the Library, TCI Members can access documents that were contributed to TCI with the restriction that they are made available to TCI Members only, and are not to be posted on any publicly available web site.
Most are large manufacturer catalogs, restricted distribution documents or files that have had extensive processing by TCI volunteers, such as page straightening, clean-up and OCR.

BSRS - Bell System Repair Specifications
Incredibly hard to find documents. Formerly D-series BSPs. Scope and plan: "These documents are primarily intended for use in Western Electric Company Service Centers in the repair of apparatus and equipment removed from Telephone Company plant." As documents are scanned and added to the Library, they will be filed here: BSRS Thanks for the scans to Astrid Smith - Connections Museum, Seattle (THG). OCR by TCI.
Each document uses a novel issue control process, updating each page individually. An index page has an issue number and date, with the current revision level of each page in the document!

ringers, C4A C4B C4C, 1, 1983-04-29.jpg
Where:
ringers, - card catalog section heading
C4A C4B C4C, - list of coded part numbers that apply (i left out color codes)
1, - card number, in the sequence for that part number
1983-04-29 - date of issue of the particular card
Where the part numbers field is blank, that's supposed to be the
front-matter for that section.

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!
Find it by searching for Complete Index BLR

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.)

Product Catalogs from 1886-1976, LME Review issues from 1924-2003, annual reports, and other publications can be downloaded directly from the Ericsson site:
