Changelog
List of changes to the bibliography collection in reverse
chronological order. This list is not exhaustive and lists only major
changes. Updates of bibliographies or new additions to the
bibliography collection are not reported here.
2003-08-18
The server moved to new hardware/software platform (so it is much
faster now).
An additional method for detection of duplicates was applied, so that
all records that share the same title and author last names are
grouped. When a list of search results is displayed, then only first
entry in such group is shown. All other entries are available through
the link visible on the right of the displayed citation. Beware, that
these duplicates may contain additional information about the
publication you are looking for (abstracts, URL's, other versions). Do
not miss it!
2002-09-06
Sorry, the master site for the bibliography collection was not
reachable for the last few days because
- the IP address of the server had changed
- we had a power-out on the weekend
- the central firewall was not properly configured
In that order.
Everything is fixed now and should be in working order.
2002-07-23
After nearly 10 years of creating and maintaining the bibliography
collection I will soon retire as the maintainer and will hand the job
over to somebody new who can devote his whole time and energy to the
task of expanding both the coverage and the functionality of the
bibliography collection.
2002-02-01
There is a new, still experimental and very
powerful search inferface available at the master site for this collection. Test it and let me know about any problems.
2000-03-13
Now there is a new mirror site for the bibliography collection that
features a search interface with the most important pages translated
to Spanish.
2000-01-13
After a power failure on the 26th of December, 1999, the bibliography
collection had been down until the 12th of January. I am sorry for the
inconvenience.
1999-12-01
The number of entries in the bibliography collection has now surpassed 1 Million!
1998-08-06
According to AltaVista there exist at least 6000 links to the Computer
Science Bibliography Collection!
1998-01-13
The simple
search interface for the bibliography collection now allows you to
search for more matches to your query by providing a pointer to the
next set of matches.
The total number of matches is still limited, though. This limit,
however, has been raised significantly, thus allowing users to scan
larger result sets.
1997-10-13
The Institute for Informatics for Engineering and
Science has dedicated one of their fastest machines solely for the
bibliography collection! Please give 'em a hand (or send them a postcard!).
The new machine speeds up searches by a factor of 3 to 7
and should help to avoid long response times that users have
experienced in the past.
1997-09-26
Adjusted the HTMl code in pages and search results to handle Netscape
4.* pecularities concerning table rendering.
1997-08-13
Just for your information I would like to show you some statistics
regarding the number of hypertext links in the bibliography collection:
| | Hyperlinks | Unique URLs |
|---|
| | number | % | number | % |
|---|
| Local | 9020 | 65.30 | 1977 | 47.54 |
|---|
| Remote | 4793 | 34.70 | 2182 | 52.46 |
|---|
| Totals | 13813 | 100.00 | 4159 | 30.11 |
|---|
As you can see in the table there are more than 2000 links in the
bibliography collection that point to other sites offering
bibliographical information and the whole weblet of the computer
science bibliography collection consists of almost 14.000 hyperlinks.
Note that the numbers above do not relate to the the bibliographical
data in the collection, but the metabibliographical data contained in
the many HTML files. For some statistics about the bibliographical
data see here.
1996-02-12
The appearance of the computer science bibliography collection has
been changed (improved, I hope).
Also, a new WWW server has been installed in order to speed up accesses.
1996-01-09
- Some mirror sites of the collection have ceased to mirror the collection, some new mirror sites have been added, better check out the list of mirror sites.
- The search interface have undergone some changes:
- advanced search interface:
- Stemming has been added for title keywords. Compression has been made an option.
- simple search interface:
- Compression has been turned into an option. A new format
for result entries has been created that resembles a citation in a
bibliography. This format has been made the default, as it is shorter
and easier to read.
- The search
interface release for mirror sites has now reached version 0.7 and
includes many improvements.
- And, of course, the collection has grown by nearly 100,000 entries since the last changelog entry.
1995-07-24
I thought I'd throw in some numbers about this bibliography collection:
The Computer Science Bibliography Collection
- currently contains 566344 references.
- is currently accessed about 200,000 times per month worldwide (including mirror sites).
- is managed with the aid of 150KB makefiles, 300KB Perl scripts and numerous other programs.
- consumes 2GB of disk space plus some 500MB of temporary space.
- needs about 6 hours for the updating of the bibliographies.
The search interfaces
- consume about 700 MBytes for the search indices.
- take about 13 CPU hours to build.
- detect 28.56% of the overall references to be duplicates and do not index them.
1995-05-21
You can now create
your own subject area by searching for whole bibliographies and
search only the bibliographies you select.
1995-05-10
The advanced
search interface now offers an easy way to search for all
publications of a certain author by turning author names into
hyperlinks in search results.
1995-05-01
The server
at the home site is now running on a faster machine and has more
disk space. That should speed up searches by a factor of 2 or 3.
The HTML pages for the bibliographies have been redesigned a tiny
bit. In particular, they now have better navigation links to higher
levels of the collection.
The reference count reached a whopping 500,000 entries! However,
note that 125,000 are duplicate entries.
1995-04-04
You can now also submit
individual references to the Computer Science Bibliography Collection
instead of whole bibliographies.
1995-03-14
The section on software engineering has
been extended to include a number of bibliographies on formal methods.
1995-02-10
The section for the bibliographies of
the Bibnet project have been moved to the miscellaneous section.
1995-01-26
I have added graphical information about the distribution of
publication dates to the pages of individual bibliographies. This is
to help users assess the scope and comprehensiveness of a
bibliography before retrieving or searching it. This is especially
helpful with the bibliographies for journals, since it becomes clear
which years are covered by the respective bibliography.
1995-01-12
The native
search interface now searches on a database with expanded
crossreferences. This improves search results for queries that include
years or conference names and also gets rid of the additional
indirection in the search results.
1995-01-09
In November 1995 I gave a talk at Konrad-Zuse-Zentrum für
Informationstechnik in Berlin on the Computer Science Bibliography
Collection. The slides I used in that talk are available as a gzipped
postscript file (sorry, German language only).
1995-10-18
I will continue to maintain the bibliography collection until the end
of 1995. After that date maintenance will be continued, but less intensely.
I am looking for sponsor(s) who would be willing to donate funds
towards the continued maintenance of the bibliography collection in
exchange for having their logos prominently displayed on the pages of
the bibliography collection. Potential sponsors can have a look at the
access statistics to find out about how
many clients use this service.
1995-09-26
A very powerful alternative search interface has been installed at the
home site of the bibliography collection. It is based on freeWAIS-sf
and allows field-based search with a full set of boolean operators. It
is still in beta testing, though.
I will be leaving the University of Karlsruhe and somebody else will
continue to maintain the bibliography collection. However, we have to
reduce the maintenance effort for the bibliography collection and
therefore some changes will take effect soon:
- The bibliography collection will not be updated in a proactive
manner any more, additions of new bibliographies and other changes
will now be done only upon requests of users like you.
- The updating frequency of the bibliography collection will be
changed from weekly to monthly. The bibliographies will now be updated
on the first Sunday of every month.
- Please direct mails concerning the bibliography collection to
liinwwwa@ira.uka.de
from now on.
- The LitServer mailserver search interface to the bibliography
collection is discontinued, it wasn't so popular anyway.
- The general structure of the bibliography collection and the
HTML pages will stay static. If you have any suggestions for
improvements then you should mail me soon.
- Contributions of new bibliographies are still welcome. However,
contributions must adhere strictly to the guidelines laid out in the
section on how to contribute. Earlier
I also tried to accommodate bibliographies that came in non-standard
formats, had changing file names or were wrapped up in archives. This
is not possible anymore.
1995-03-07
I stopped recording additions to the bibliography collection. Log
records have shown that this page was read by only very few users and I did
not really keep this log up-to-date lately anyway.
