Welcome to the TCI Library

FLASH: We have updated the library's software
and most of the site has been tested.
Let us know when something isn't working correctly.
The help texts will be updated in the near future.

The TCI Library was created by Paul Wills and 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 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, 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.

Hints for using the TCI Library

"Menu Bar" for site navigation.
Many menu choices are hidden until you mouse over the menu.  If you want help getting started, see the links under the word "Introduction" in the Menu Bar.
The user interface is oriented toward the user’s choice to either Browse or Search for information.  The Browse the Library menu entry offers many quick links to move around the Library quickly.  Try it!

Three search options.
The Library’s keyword-based searches, called Basic Search and Advanced Search, accept keywords as short as 2 characters (WE, AE, etc.) and search strings up to 255 characters.  If you get more than 1,000 items, refine your search or try the Google Search option.
Library INBOX.
The INBOX may hold some files that have been submitted but not fully processed into the Library.  These are often topics of current discussion on the TCI Listserv.
Finding BSPs.
Many BSPs are currently only identified by BSP number. If a text search doesn’t produce a BSP, try looking in one of the many BSP index documents to find a BSP number for the product you are researching just as you would do if referencing a paper library of the BSPs. Then enter the BSP number in the search box.



Telephone Collectors International was incorporated under the laws of the state of Kansas on May 13, 1986. The goal of the organization is "to educate the public, as well as the members of the Corporation, regarding the history of telephony, the value of old telephones and related items, their collectability and preservation; to research telephone history and publish and provide literature thereon; to promote the public exhibition of old telephones and related items; and to promote common courtesies and guidelines for use by the public." Telephone Collectors International is recognized by the Internal Revenue Service as a 501(c)(3) organization, to which U.S. tax deductible contributions can be made.
