This month, JCO becomes the only orthodontic journal in the world (of those that have been in existence for more than a decade) to place its entire archive online. Every issue of JCO ever published--more than 400 monthly issues since our inception in September 1967--is now available on our website.
If you are familiar with the former CD-ROM version of JCO, the Online Archive articles published before 1999 are accessible in much the same way. When you select an article from the contents listing, the text appears on your screen immediately, without waiting for the images to load. Hyperlinks take you quickly to figures, references, footnotes, tables, and author biographies. You can also scroll through the figures, references, footnotes, or tables one by one if you prefer. You can print out text and graphics by clicking on an icon at the top.

Articles published from 1999 to the present are available in both this XML format and in a PDF version that duplicates the article as it appears in print. You can scroll through, search, or print out PDF versions using Adobe Acrobat Reader, which can be downloaded at no charge from www.adobe.com.
You can use the archive to browse through timeless material from the past or to compare today's techniques with those of 20 or 30 years ago. The Online Archive search engine will be a valuable resource, whether for research or for looking up that pearl you might have seen published in JCO three or four years ago. Without flipping through endless back issues and indices, you'll be able to pull up a matching list of articles using any string of characters--an author, part of the title, or merely part of the text. The search results display the title, authors, issue date, and page numbers of each article, along with the first few words of text.
Current issues are posted to the website as soon as they go into the mail, making this the most up-to-date information in orthodontics. As long as you maintain a subscription to the print version of JCO, you will have access to recent issues at no additional charge. All you have to do is select a user name and password when you first log in, after entering a key code that you will receive in the mail.
A complete set of JCO back issues at today's single-copy price would cost more than $6,000 (and some early editions are out of print), not to mention the shelf space required for storage. The defunct CD-ROM version sold for more than $700 and was updated only annually, rather than monthly. Now, unlimited access to the entire Online Archive, back to 1967, is available for a fee of only $120 per year, as long as you keep your print subscription in force. Note that this price is the same throughout the world, since no shipping and postage are involved.
To provide more options for students and researchers, we have also instituted inexpensive 24-hour and monthly access fees, which do not require concurrent subscriptions. In addition, the search engine works independently; you do not have to pay the access fee and log in if you simply want to look up a list of articles by keyword or author. Editor's Corners, Readers' Corners, Pearls, and other selected articles marked "Free Access" are available to any user at no charge.
Digitizing this entire archive in a format that is easy to use on the Internet has been a monumental task for our editors and programmers. We are continually reviewing every article in the archive to make sure the text is correct and that all the links function properly. If you discover any glitches while browsing through, however, we'd appreciate an e-mail so we can correct them immediately.
We invite you to see how the Online Archive works by visiting our website at www.jco-online.com and clicking on the navigation bar at the left of your screen. We think you'll be so impressed that you'll want to sign up and start using it right away.
