The Stata Technical Bulletin (STB) has changed to the Stata Journal; see http://www.stata-journal.com for more information.
For ten years, the Stata Technical Bulletin served as a means of distributing new commands and Stata updates, both user-written and "official". Although the last issue of the STB was published in June 2001, many STB articles continue to be of interest to users. The following FAQ was preserved to inform new Stata users about the STB.
The Stata Technical Bulletin (STB, ISN 1097-8879) was a printed journal containing articles related to Stata and software additions to Stata to which users paid to subscribe. An electronic version of the journal was also available.
In addition, accompanying each issue is software that can be installed into Stata. The software is available free over the Internet to both subscribers and nonsubscribers.
The STB promotes communication among Stata users of all disciplines and all levels of sophistication. The STB contains articles written by Stata users, StataCorp employees, and others.
The STB has in the past been the vehicle by which new features were first added to Stata and distributed.
The Editor of the STB is
H. Joseph Newton
Department of Statistics, Texas A&M University
College Station, Texas 77843
979-845-3132
979-845-3144 FAX

The Associate Editors of the STB are
Christopher Baum, Boston College
Nicholas J. Cox, University of Durham
Joanne M. Garrett, University of North Carolina
Marcello Pagano, Harvard School of Public Health
J. Patrick Royston, UK Medical Research Council
Jeroen Weesie, Utrecht University
The STB is published by Stata Press, a division of StataCorp LP.
Articles in the STB are called inserts, and each insert in the STB is assigned a letter-number code such as xyz42, xyz43, or xyz43.1.
In this code, a number like xyz42 indicates that this article is number 42 in the xyz category. A number like xyz43.1 indicates that this article is an update of the original xyz43 article with the same or different authors.
The following category codes are used:
| General categories: | |||
|
an cc dm dt gr in |
announcements communications and letters data management datasets graphics instruction |
ip os qs tt zz |
instruction on programming operating system, hardware, and interprogram communication questions and suggestions teaching not elsewhere classified |

The appropriate citation for an STB insert is
Author Name. Year. insert_number: Title. Stata Technical Bulletin issue_number: page_range.
For example,
Wright, E. and P. Royston. 1997. sbe15: Age-specific reference intervals for normally distributed data. Stata Technical Bulletin 38: 4-9.
If you found the same article in the STB Reprints, an appropriate citation would be
Wright, E. and P. Royston. 1998. sbe15: Age-specific reference intervals for normally distributed data. In The Stata Technical Bulletin Reprints, vol. 7, ed. H. J. Newton, 93-100. College Station, TX: StataCorp.
Issues were published in January, March, May, July, September, and November of each year. Issues are numbered sequentially and are referred to as STB-1, STB-2, and so on. STB-49, for instance, refers to the May 1999 issue.
The STB began publication in May 1991 (STB-1) and ended in publication May 2001 (STB-61).
Every year, a bound book was printed containing the previous year's issues, May through March. These books are referred to as the STB Reprints.
Note that Volume 10 contains seven issues of the STB, since it is the last Reprints volume.
Subscriptions to the STB are no longer available; instead, we suggest that you subscribe to The Stata Journal.

The list you see when you type search meta analysis will be up to date if you have installed the latest official updates; to obtain the latest stata updates, point your browser to http://www.stata.com/support/updates.
If a listed entry begins with the letters STB, it was published in the STB. For instance, the last listed item -- sbe16 -- can be found in STB-38 and also in STB Reprints volume 7.
If a listed entry says “help filename if installed”, there is software associated with that entry. All of the above listed entries have software associated with them, but that is not always the case:

Neither of the last two STB inserts above has software associated with it.
In any case, in our previous request, search suggested STB insert sbe16 of STB-38 and said "help meta if installed". In all probability, meta is not installed:
. help meta help for meta not found try help contents or search meta
To install insert sbe16 of STB-38 from inside Stata, you could use the net command:
. net from http://www.stata.com . net cd stb . net cd stb38 . net describe sbe16 . net install sbe16
or you could follow these steps:

The STB software is also available from other Internet sources in a downloadable format. If your Stata is not connected to the Internet but you have access to the Internet through a browser on that or another computer.
Do not seek other Internet sources simply in hopes of finding a faster connection. The easiest way to install the STB software is to obtain the software from www.stata.com using StataStata'srsquo;s built-in Internet capabilities; see above.
The following sites maintain the STB software in alternative formats:
http://www.hsph.harvard.edu/statalist/stb, Harvard University, USA
http://lib.stat.cmu.edu/stata/, Carnegie Mellon University, USA
Each of these sites provides one ZIP file per STB, but installing from the zip files is complicated because the zip files contain different things. To install from an alternate site

Appropriate submissions include articles about new Stata commands (ado-files), programming tutorials, illustrations of data-analysis techniques, reports on other programs, announcements, questions, and suggestions.
Very active Stata programmers, especially those who exchange ado-files with others, worry about choosing unique names for their commands.
Say you write a new command called reghpb, and somebody else on the other side of the world also writes a new command of that name. Usually, when that occurs it does not matter because the two new commands never meet on the same computer. If both programmers make their commands available to others, however, someone could want both. If both commands have the same name, that will not be possible.
Thus, the naming rules for user-submitted ado-files are that
We think that really nice names should be reserved for really nice commands that are used by a large fraction of the Stata community. So any command that fits the above definition is or will become part of Stata as it is distributed by StataCorp.
Programmers outside StataCorp can write really nice commands, but their commands get really nice names only after being published in the STB. They may be distributed under not-so-nice names and then renamed when they are adopted for inclusion into Stata. At that point, such programmers will also get a really nice reference in the manual.
You may not submit programs to with names shorter than 4 characters to the STB. Such names are reserved for private use and, on rare occasions, for use for common commands (think of d for describe).
You may send your submission as a group of files on media or by email.
